Perhaps a great reason for the popularity of stamp collecting is the stories about valuable stamps. A lot of people have heard that some of these little things could sometimes cost thousands of dollars. Finding a rare and valuable stamp is often a philatelist’s dream. Unfortunately, this induces some people with bad intentions to create forged stamps. As such, many stamp collectors find their craft to be risky. Luckily, such anomalies can be avoided by making use of expert stamp collector certificates.

Like anything valuable, such as jewelry, money, signature clothing, rare stamps are subject to forgery. The regrettable proliferation of fraudulent stamps has led avid collectors to look for ways to protect themselves. The most popular way doing so is availing the services of expert stamp collectors and organizations to certify the authenticity of stamps being purchased.

One of the most sought after authorities in stamp collecting is the American Philatelic Society (APS), which offers such certification service which they refer to as expertizing service. A collector simply sends a stamp in question to the American Philatelic Expertizing Service (APEX), the certifying division of APS, to their headquarters at Pennsylvania. The service has been around since 1903. The stamp is then assigned a number and then photographed. The stamp is then examined by up to five expert collectors among 170 philatelic specialists. The identity of the collectors who availed of the service would not be disclosed to the experts, and conversely, the experts’ identities would not be disclosed as well.

The service could take 90 days to be completed. A unanimous decision must be made by the experts and if the panel fails to do so, APEX declines to give an opinion refunds all fees, less administrative charges. Once a formal opinion is agreed upon, it is written on a certificate and returned to the owner with the item. The comments made by the panel would be kept in the permanent records of APEX for future reference. Opinions are limited only of stamps’ genuineness and the APEX never accepts requests for market value appraisal. If the owner disagrees with APEX’s opinion, there is an option for reexamination within a year from the issuance of the certificate.

The APEX provides a guarantee on their certified items. If a collector buys a stamp with an APEX certification attesting the item’s authenticity but it is subsequently shown to be fraudulent, misidentified, or modified, APEX would pay up to 5,000USD provided that the guarantee is still valid and there are no other warrantees given for the item. Items that were subject to change (thinning, disturbance of the gum, torn, etc.) after the issuance of certificate would not be included in the guarantee. Should APEX’s certification be proven wrong, the service will purchase the item from the owner. The value of the item will be determined by APEX based on the selling price, receipts submitted by the owner, placed value of the item during the time of certification, and the judgment of a panel of experts.

Should APEX disagree with the contention to its certification, the owner may appeal to a disputes panel comprised of three members of the American Philatelic Society. And the decision of the panel would be based on Pennsylvania state laws, which would be binding for both parties.

The fees for the service begin at 25USD for an item valued at 1,000USD or less according to the Scott catalog. Items of higher value would be charged 2% of the appraised value according to the catalog. Items not listed in the catalog would be initially charged 25USD. Should an item of a high value be considered counterfeit, its fee would be adjusted to the minimum fee of $25 USD; the difference with the original rate paid would be refunded.

There are other expert stamp collector certificate issuance services. Some of them are listed online. Many avid followers of philately find such services very valuable, saving time, effort and money, and decreasing the incidents of forgery. With expert stamp collector certificates, the world becomes a better place for serious philatelists.

Scuba diving has attracted the attention of many enthusiasts all over the globe. It seems to be a very fulfilling and enjoyable activity. Some people have made careers out of their passion for scuba diving. The world has sensationalized scuba diving in such a way that it has helped preserve the environment and greatly contributed to the awareness regarding the environmental issues that are associated with our aquatic resources.

One of the major and popular issues that is continuously being discussed in the scuba diving arena is the conservation of air under water. An emerging scuba apparatus design is called a re-breather, which can help people address the concern about rapid air consumption. The apparatus functions in such a way that the exhaled air by the diver is stripped of carbon dioxide and is re-circulated to the air chamber. This way, one can enjoy the deep seas much longer. However, in most cases, divers don’t have such an apparatus.

Having insufficient air under water poses grave risks for the diver. One of the major causes of brain damage from scuba diving activities is the prolonged lack of oxygen that flows into the brain. Our brains rely on oxygen to deliver the necessary nutrients for it to function and if a diver doesn’t know how to properly manage his air, he is exposing himself to the risk of running out of breathable air.

So, what are some of the ways by which a scuba diver can conserve air while diving? One of the most controversial suggestions regarding the issue is to hold one’s breath during dives to be able to conserve air. In real life, one shouldn’t make breathe holding a diving habit. A simple analogy for holding one’s breath is it is like killing the chicken to be able to get the eggs. It’s really a matter of priority. Do you want to conserve air from your tank while risking yourself to the negative effects of carbon dioxide saturation? The build up of carbon in the brain is dangerous because it pollutes the blood stream and deprives all the parts of the body from the much-needed gas that is oxygen.

However, holding one’s breath has some useful applications. It can be used to control buoyancy under water. Professionals to ascend a maximum of one foot, but nothing more than that usually use it. One should also remember that it is a “no-no” to hold one’s breath while ascending rapidly.

A more accepted way of conserving one’s air under water is to practice slow breathing. When you inhale and exhale, you should do it in a way that you fully go through the process. Breathing completely and slowly is the way to go if you really want to conserve water under water. It makes the whole process of respiration more efficient and effective as compared to taking short inhales and making short exhales.

Another tip (which is related to the one given above) is that it is more advisable to make big kicks as compared to making tiny ones. The concept behind this is that it is a more efficient way to move under water, therefore, you conserve your energy and your body needs less oxygen.

Sometimes, divers usually do all the things that are mentioned above and they still find themselves consuming too much air. For all the air hogs out there, the problem might not be under water. Being physically fit is very important in scuba diving. A diver who smokes would most definitely consume much more air more rapidly than a diver who is in good physical condition. Looking at the issue of air conservation under water from a more holistic point of view is perhaps the best tip that one can imbibe.

The following are basic tips and advice to know what is fake and what is not:

Gum or re-gummed, that is the question

First things first, what does it mean when a stamp is said to have been re-gummed?

A re-gummed stamp basically means that the stamp no longer contains gum in its one hundred percent original content.

A gum is said to have been original when the gum is produced from the United States postal authority or any other official postal authority such as Newfoundland or Canada. The instance a particular individual has applied his own gum blend to the stamp’s back is the instance wherein the stamp is considered as officially re-gummed.

Why is re-gumming done?

Re-gumming is made to stamps to make it appear better and enhanced, therefore further increasing the stamp’s value. Fraud occurs when a particular collector buys a stamp and was informed that the stamp has an original gum, but is really a re-gummed one.

How to know which is which?

The most easy and convenient way to detect which gum is original and which is counterfeit is by simply comparing an original gum from a re-gummed one.

Try to take note of the following. A re-gummed stamp has a textured and dull appearance with little inconsistencies in the thickness of the gum or when it is reflected in the light. Also, there are stamps that have been re-gummed and appear to have a surface that is glossy. The same appearance holds with stamps that are imperforated.

A stamp that contains a watermark can be easily seen on a stamp that has been re-gummed.
Meanwhile, a stamp that was originally gummed has a watermark that could only be seen when the stamp is dipped in a tray of watermark using fluid for watermark. In the absence of such a fluid, the watermark in an original gum could also be seen when the stamp is put up to a light that is very strong.

Observe, try to notice if the watermark seems to have been impressed in the gum. If so, start to be suspicious.

Another tip is that a stamp that has been re-gummed will most likely curl if it is placed down with its face on the hand’s palm. A stamp that has been originally gummed will not do that.
One sure sign that a stamp has been re-gummed is to check on the stamps tips. If the perforation feels sharp, it surely has been re-gummed. Usually, an originally gummed stamp will feel soft.

Fortunately or unfortunately, a good re-gummer still has a way to fake it. What he usually does is that he will try to file patiently down the tips of the perforations in order to make them soft.

The only way to effectively differentiate this is via looking through them under a strong magnifying glass.

Another clue to know a re-gum from an original is to check and see if the gum extends well into the holes of the perforation. This situation never occurs in an original because the perforation is done after applying the gum.

However, a re-gummer still has a way to fake it via filing out the perforated holes in order to eliminate any excess gum. But most likely, they will almost always miss a spot.

Stamps that are re-perforated

Believe it or not, these types of stamps are prevalent than most collectors think. This basically means that a perforation has been done privately by an individual and not officially by the United States Postal Service. Why do individuals do it then? This is done in order to increase the stamp’s value.

Stamps that were perforated officially have holes that are shaped in oval form and are cut less cleanly than perforations done privately. When seen closely, perforations that are originally done have little paper tufts that extend to the holes.

All in all, stamp collecting – contrary to popular belief – is a challenging and an adventurous hobby. It requires diligence, patience, perseverance and a lot of passion. That is if you know what to look for and how.

Carl Pelander

He was a man from New York City who lived from the years 1893 to 1966. His expertise was Scandinavian stamps as he has collected such items when he was still young. It was in the year 1937 when he began to deal and auction stamps. Since then he has held 130 auctions from the year 1940 up to the year 1963. The stamps he usually dealt with were from Scandinavia, of which the collection from Agathon Faberge’ was included as well as from Caroline Cromwell.

Believe it or not, he was also the one responsible for selling the famous US collection of Ferrars H Tows.

Thanks to his expertise, a book was published entitled The Postal Issues of Finland. He was also able to produce a check list of stamps that included those that come from Denmark, Iceland, Greenland, Norway, Finland, and West Indies, Sweden.

Pelander was also able to form the Stamp Club of those who are Finnish and American during 1935. The club is now known as the Scandinavian Collectors Club.

Pelander edited the journal the club produced, The Posthorn from 1943 to 1949 and even financially helped the club out during trying times.

Philip Ward Jr

He was a man from Philadelphia who was most known to buy and sell great and rare stamps. A lot of auctions were conducted by him wherein amazing materials were available from a series of valuable collections.

His most famous collections were stamps from US that were unused, letters from presidents, autographs from presidents, the history of Philadelphia post, etc.

Another of his most famous collection was the US Revenues wherein it contained a set of complete centers that are inverted. Unbelievably, he also had a collection of stamps called Match and Medicine.

William W Hicks

Hicks was from Pennsylvania, and specialized in three-cent US stamps issued in the years 1851 up to 1857. He founded the three cent unit. William Hicks built the largest as well as complete collection of railroad cancels from the US during his time.

George Ward Linn

He was a man from Ohio who was most famous for his weekly stamp news issued on November 5 1928. Since when he was young, he was able to edit and publish journals on philately including monographs until his retirement in the year 1965.

Linn was the son of a publisher and a printer. During his active stamp collecting life, he also auctioned off some stamps. He was also interested in the literature of philately that in 1902 he also came out with the Philatelic Literature.

George Linn supported a lot of stamp clubs and societies beginning with the Club of the Columbus Philatelic. He was also the one responsible for making Ohio the one location where the American Philatelic Association holds its convention.

Harry Weiss

He was a man from Illinois and was considered the most read columnist in philately during his time.

He regularly wrote a column which provided tips, stories on the hobby of stamp collecting.
During 1946, he organized the Laboratory of the Midwest Philately wherein it offered a lot of services to stamp collectors as well as estates on stamp appraisals, mounting, and other expert information.

Louise Boyd Dale

She is considered by America as its most distinguished stamp collector. Her love for philately began early on in her life thanks to the influence of her father, whom she also considered as her mentor.

There were many collections that she built, specifically those from Asia and British Africa. Most of her collections were put under the foundation of her daughter, Anne Boyd Lichtenstein. Now, these are available to stamp collectors and students to further support research on philately.

It was in 1956 wherein she was the first ever woman appointed to be a judge in the exhibition of international philately, also called as FIPEX.

In the same year, she also became the first woman from America to provide her signature in the list of distinguished philatelists. Four years later, she was included and appointed to the International Stamp Exhibition in London.

All in all, stamp collecting requires no special skill or talent just a passionate love if not a healthy obsession for stamps.

If you’re adventurous and unconventional, a career in scuba diving may be right for you. Usually, those who pursue scuba diving careers were scuba diving enthusiasts who wish to take their hobby to a different level. Scuba diving is impossible to compare to other career choices.

Instead of causing stress, it is a rejuvenating activity and doing something you like that pays you is a real serendipity. You get to use your knowledge of the sport with other people who share your interest. In scuba diving, there’s no unappreciative boss and annoying colleagues.

Starting a scuba diving career is a bit like other careers, though. You need to have an extreme interest in diving, then develop your abilities. Though it seems so easy since scuba diving sounds like it’s all about fun, there’s more to learn to become a scuba diving instructor. You have to master not only the craft of teaching but also develop an expertise in diving.

Like other professionals, scuba diving instructors also used to be students. They began with easier courses on scuba diving and then slowly moved on to more advanced courses. Of course, through the process, they were able to see more to scuba diving than just having fun while diving. They were able to see a different side of scuba diving that encourages them to share the sport with others.

If you ask any scuba diver instructor, he’ll probably tell you much about what scuba diving has to offer. For the love of the sport and the desire to let others experience the beauty of scuba diving, they ended up becoming a scuba diver instructor.

Although you might think that scuba diver instructors know everything there is to learn, the truth is there is still so much to learn about scuba diving. Scuba diving is an evolving activity. The military and scientists use it as well. Nobody can possibly learn everything about scuba diving.

It offers a whole new world and constantly opens more doors to exploring the mysteries of the underwater life. If you are up to this challenge, then you should seriously consider a career in scuba diving.

To be a scuba diving instructor, you first need to be a dive master. There are numerous scuba diving schools or agencies where you can earn a dive master certification.

By the end of an instructor development course, you are expected to learn more than just the basics of diving. You’ll be taught about diving standards, safety and regulations and the scuba diving system as it relates to the law. Of course, you’ll learn techniques that you can employ to effectively teach your future students.

This extensive course definitely prepares you to wear the certification of a master of scuba diving. You learn everything you need to know to kick-start your career in scuba diving. Of course, the rest of the learning process will follow once you have started your craft. Like many other careers, you only get about 20% of the knowledge from training, and you derive the rest in the real world.

As a scuba diving instructor, students expect a lot from you. You need to be able to teach scuba divers how to dive safely and have fun at the same time. That is quite a responsibility. Your students have placed their lives in your hands, but that doesn’t mean it’ll be easy to teach them how to stay safe and remain alive while underwater.

There are other factors to consider when pursuing a career as a scuba diver instructor. Like other careers, there’s marketing involved. You may have to learn a little how to prepare sales literature as well as product marketing. You don’t have to buy everything they advertise but you need to understand the scuba diving business industry. The market in scuba diving largely affects your job and your students as well.

However, before you excitedly jump in bear in mind that scuba diving poses some hazards. We have briefly covered these but let’s dig in and explore them further.

The most common of these are pressure related injuries, such as decompression sickness or air embolism. To avoid these injuries, you must be able to calculate how long you can safely stay underwater. You also need to know the proper descent and ascent rates, or else you might find yourself fatally inflicted with these pressure related illnesses.

Most aquatic animals don’t pose any risks to divers. In fact, a diver may be a threat to them. For example, coral could be killed by just one touch.

However, there are also a few marine life forms that may injure a diver. The most common include jellyfishes, stinging corals, fire corals, and sea urchins. Sharks and poisonous sea animals can also injure divers, but very rarely. Generally, animals attack humans only when they are provoked.

Although, there have been recorded unprovoked shark attacks, the number is still few. Statistics show that your odds of being attacked by one of these dangerous aquatic animals are 1 in 12 million. You’re more likely to be attacked by a dog or a snake when you’re above water.

Scuba diving, being a visual underwater experience, doesn’t include altering the underwater habitat. Divers shouldn’t touch anything, be it a plant, animal or an object underwater.

Usually, the best scuba diving location is where there is plentiful marine life. Of course, it is an added advantage for divers if the water is clear and the temperature warm. That reveals the aquatic beauty clearly and is a better adjustment to the underwater temperature.

We will look at specific diving locations in an upcoming chapter, but briefly the most popular diving destination is the Caribbean. The Caribbean coral reefs are incredibly colorful and abound with marine life. Different types of fish find shelter among these coral reefs. Most parts of the Caribbean region have been designated to be marine sanctuaries thus fishing and other human activities that could damage the marine life are prohibited.

Shipwreck sites are usually considered off limits as well. Aside from providing valuable treasure and clues to our rich history, these sunken ships also provide aquatic animals an ideal nesting or breeding area. These ships not only add beauty to the ocean floors, they also have some utilitarian purposes for aquatic animals that live in deep places where resources are very scarce.

It’s been said that there are about 75,000 sunken ships in the North America area alone. These locations also attract thousands of divers from around the world. Some hoped to find buried treasures while others seek fame for having discovered some important historical links. Still, several dive for recreation purposes just to enjoy what the underwater environment has to offer.

Other protected areas that are also famous dive destinations are the South Pacific, Indian Ocean and the Red Sea. The government and environment organizations try to conserve the beauty of the habitat of these aquatic animals and plants. Although these destinations are open for viewing and recreational diving, enough marine police are assigned to ensure that the divers abide by the conservation rules and regulations.

It is appropriate to raise these marine conservation issues, especially now with our advanced technology. Technology advancements mean a lesser concern for the environment. Just take a look at what’s above sea level. There are high-rise buildings and large factories that contribute to pollution.

Currently, mankind is slowly able to invade the depths of the ocean, as well. In fact, submersibles now allow humans to go into the deepest parts of the oceans. Marine biologists, geologists, archaeologists and scientists are using such technology to enable them to stay in the ocean for long periods of time so they can learn more in their fields of study.

Who knows what the near future has in store for deep water exploration?

In order to stay safe while underwater and make scuba diving a wonderful experience, you should ensure that you are able to get proper training before you dive in. Scuba diving isn’t a sport that you can learn on your own. You have to consult the expertise of scuba diving instructors and undergo specialized training to learn the ins and outs of scuba diving.

If you’re planning to scuba dive over the weekend, the first thing you should check is if you’re physically fit for the challenge. Aside from being a decent swimmer, you have to pass a certain fitness level. Scuba diving could be fatal to those who aren’t physically strong enough. If you’re not sure about your level of fitness, you can try talking about your scuba diving plans with your doctor.

Even if you’re just planning to make scuba diving a one-time experience during your vacation in the tropics, you have to go through a basic scuba diving course. Most resorts have dive shops and scuba diving courses. You may want to check on these. Knowing the basics of scuba diving will enable you to go scuba diving, but you will need proper supervision from scuba diving professionals to ensure that your scuba diving experience will be as safe as possible.

When you’re about a hundred feet below the surface, pressure builds up and your body starts reacting to too much nitrogen in your bloodstream. When this unexpected difficulty happens, you might not be able to think clearly. In fact, you could panic, which isn’t advisable when you’re underwater. That’s why, it is important to have proper training.

With proper training, you’ll be able to plan your dive. So when you’re feeling a bit nervous while underwater, you don’t have to think about what you need to do, you just have to follow your dive plan.

To help you achieve your dive plan, you will need scuba diving equipment, such as a dive computer. A dive computer calculates and displays your dive depth, ascent rate, time, etc. These details are very helpful to prevent any decompression or pressure related injuries. These injuries such as Nitrogen Narcosis, could be fatal to divers.

Once you’ve tried scuba diving and you’ve enjoyed it so much that you want to make it your lifetime sport, you will have to go a little further with your scuba diving training. There are many recognized scuba diving training agencies where you can get your certification.

A Basic Certification in scuba diving involves both theoretical and practical aspects of the course. You can work in a swimming pool or diving school and pass written exams on diving to become certified. Once of the toughest challenges a diving student may face during his certification process is learning to use a dive table. Usually, a student will undergo a dive operation using a giant dive table that will hopefully, aid him or her in mastering the subject.

An Open Water Certification on the other hand, will require you to go somewhere, maybe in the tropical areas, where scuba diving is in season. Children who are 14 years old or younger won’t be able to get fully certified, but if they plan to obtain a full certification soon, they can enroll themselves in some scuba diving classes to prepare for them.

A good diving course will also teach you how to properly select, care and use scuba diving gear. Of course, you will learn how to scuba dive safely, even without any supervision. By taking up a scuba diving course, you can improve on your breathing techniques and other scuba diving skills to make your diving experience more enjoyable.

So if you’re up to the exciting scuba diving challenges, then get started, breathe deeply, and dive just right in. Scuba diving could be your ticket to an extreme underwater adventure.

Believe it or not, investing in rare stamps is a normal occurrence. Usually, the collection and gathering of rare stamps is a hobby that is better appreciated by the advanced collectors.
Unbelievably, rare stamps are investments that are of the tangible kind. Compared to art they are also a worthwhile and enjoyable investment especially for enthusiasts.

First things first, the fact is that rare stamps are really, definitely very rare. But what is it that makes a stamp rare?

The following are some of the reasons as well as circumstances that make a stamp that rare, expensive stamp that everyone would want to own.

The mother of all rare stamps

Believe it or not, there exists the stamp that would be considered as the mother of all rare stamps and quite possibly the stamp that – if given the chance – would be the one to rule them all.

The stamp that costs one cent is the British Guiana. This stamp is currently considered as the rarest stamp in the whole world because only one of such kind was made. This stamp was reportedly discovered by a school boy back in the year 1873.

Another valuable rare stamp is called the Penny Black where it is also considered as a very rare and valuable item for collectors.

The father of all rare stamp collectors

A man with the name Philipp von Ferrary who lived during the years 1850 until 1917 was considered to be the collector of all collectors when he was able to amass stamps from all places in the world.

Ferrary, as he was fondly called by his clients and almost everyone, began the hobby of collecting stamps when he was young. Since he inherited a great fortune, he made it his life long quest to buy stamps that are rare.

On the fifteenth of January, 1915, he relegated to the Berlin Post museum his collections. But since he was an Austrian – who at that time was residing in France during the First World War – he left his albums to the embassy of Austria & left for Switzerland where he soon died.

Post world war one brought on the government of France to confiscate his collection. Since then, most rare stamps have a stamp of “ex-Ferrary” on them, because almost always, the stamps may have previously belonged to him.

Rare stamps found in a dresser

You know you have in your possession a rare stamp when people are suing you to have it back.

It was one hundred and fifty thousand dollars worth of stamps that a judge granted the stamp’s original owners when it was found that it was included in the dresser a Robert Ganter bought in a used store that sells furniture.

The original owners discovered Ganter’s find when the latter issued an ad in a stamp catalog for collectors and offering it up to be sold.

Buying rare stamps is a cinch

So just how is one supposed to buy rare stamps when they see one? The best method is by simply buying the best stamp that you could possibly afford.

New rare stamps recently unveiled in Asia
Beginning in April of this year (2006), stamps that highlight Vietnam’s birds, specifically the partridges as well as pheasants of the country was launched in Vietnam’s Ministry of Post and Telecommunication.

These rare stamps provide the people who live in Vietnam with a magnificent documentation of how the country’s birds thrive. The birds that were included in the stamp include a partridge whose neck is orange in color; its scientific name is arborophila davidi. Other birds in the stamps include lophura hatinhensis or the more popularly known Vietnamese pheasant.

Why are these birds featured in such a stamp series? For one, putting their pictures on a stamp is one way to immortalize their existence as they are currently considered as endangered. Their populations have been slowly dwindling due to the loss of their natural habitat as well as hunting.

What do the stamps represent then? The series also aims to showcase the varied and special life that Vietnam’s birds live.

All in all, collecting rare stamps is a fun, enjoyable and interesting activity to do especially if rare stamps are your cup of tea.

Bouyancy Compensator

Who wouldn’t want to explore the world under the sea? Mankind has always been fascinated with life underwater. Because of this great fascination, extensive research and amazing inventions have given us the chance to breathe underwater so we can observe or simply have fun in dealing with aquatic animals.

However, breathing underwater isn’t just simply bringing a tank full of air with you when you dive. There are many things that you need to consider. Staying underwater is totally different from living on land.

For one, humans don’t have the gills that can extract oxygen from the water. Air pressure is also significantly different from water pressure. The human body isn’t adapted to high-pressure changes. Controlling your buoyancy and avoiding losing body heat when underwater are also major considerations.

Fortunately, probably everything that a scuba diver needs to safely explore the depths of the ocean is available. There’s the mask, snorkel, fins, regulators and diving suits to name just a few. These equipments allow the diver to breathe, control their position and stay warm underwater.

To breathe underwater, a scuba diver wears a metal tank full of compressed air. A regulator is attached to this tank, which adjusts the air pressure to match that of the surroundings so the diver can breathe comfortably. The regulator delivers air through a mouthpiece, which the diver uses to inhale and exhale. Breathing through your mouth comes naturally, so you don’t need to add that to your worries.

Another hose is attached to a regulator to control the diver’s buoyancy. It is attached to an air bladder that is adjustable. Since the diver wears this as a vest, adding air into it would make him more buoyant, and thus, he rises. When he releases the air, the opposite happens.

These buoyancy compensators also help a scuba diver achieve neutral buoyancy. When you are in neutral buoyancy, you can stay at a constant depth without much effort. This minimizes gas consumption due to swimming.

Divers also wear lead weights as a belt to allow them to descend and stay underwater. The weights are evenly spaced to achieve proper balance. During emergency situations, a diver can quickly release these belts to rise to the surface.

A diver’s suit is really incredible. It is made of a compressible substance, thus when you descend, it reduces the volume, and when you ascend, it expands. They are very helpful in conveniently controlling one’s buoyancy.

A suit can also provide thermal insulation. A wetsuit, for example, is usually made of neoprene that has poor thermal conductivity, which minimizes body heat loss to the surrounding water.

Another way that a driver’s suit can reduce loss of body heat is by trapping a layer of water between the suit and human skin. The wetsuit is very well sealed at the neck, wrist and legs thus water flow rate is reduced. This technique in reducing heat loss is known as convection, which is the same principle used in the concept of semi-dry.

A dry suit on the other hand keeps the diver dry, as opposed to a wetsuit. Frigid water can’t penetrate a dry suit. Preferably, dry suit undergarments are also worn for better insulation. A dry suit keeps a thin air layer inside that helps keep a diver warm.

Of course, to be able to familiarize yourself better with scuba diving gear, it is best if you get yourself a certification by passing a scuba diving course. In the course, you’ll not only learn about the equipment, you’ll also be taught how to adapt to diving.

During the course, student divers learn how to achieve neutral buoyancy. Through various swimming exercises, they learn how to control their breathing rate. A diver should know how to breathe in a slow but continuous manner.

At the end of the course, you are expected to know some safety procedures in diving, such as how to clear your mask in case water leaks in, how to avoid any mishaps while underwater, and of course, how to help a fellow diver in need.
Conventional hand signals are used underwater to communicate.

As a certified diver, you can refill your own air tanks, buy scuba diving gear and scuba dive anywhere in the world. Scuba diving businesses require this certification as proof that you can well manage yourself underwater.

Multiple country collecting

Collecting stamps from one country compared to collecting stamps from various nations is better as there is a lot more time and effort to have access to more stamps locally than internationally.

For instance, it is a bit difficult to complete an Austrian stamp collection because of its rarity and only a few stamps are ever available.

The easiest and probably the most famous stamp to collect are those that come from one’s own country.

However it all depends on your own preference. For instance, stamps from Austria began to be collected through a specific motif that a particular stamp or group of stamps have. An example would be the collection of stamps as according to the pictures they have, such as flowers, dogs, trains, paintings, ships, buildings, weapons or women.

However, a beginning stamp collector or those that intend to collect on an average basis may do well to start gathering stamps from their own country.

Stamps that are issued fresh hot of the post are very affordable. Believe it or not, stamps that have just been released may be bought with no additional charge from any postal office right on the day of its issuance.

Beautiful US stamps about beautiful US

If you are willing to collect stamps about the beautiful country that is the US of A, there are a set of stamps out there which showcase such.
The Smoky Mountains of North Carolina, for instance are shown in the stamp issued by the United States Postal Service. The stamp that costs a mere seventy-five cents shows the Great Smokey Mountain during sunset as photographed by David Muench from California, specifically in Santa Barbara.

The breathtaking picture view also has portions of Tennessee and North Carolina. This national park is best known for its diverse plant life as well as animal life as one will definitely see when he hikes along its eight hundred mile trail.

Another beautiful US landmark that has been immortalized in a stamp is the Yosemite National Park. The stamp costs eight-four US cents and it features a picture of the valley gates of the Yosemite as photographed by Galen Rowell of California, specifically Emervville.

If you are a nature lover, or even if you are not, collecting the stamp will most probably make you one.

Yosemite Park was established as such on the first of October in the year 1890. The park boasts of a variety of natural features and geographical wonders such as meadows that stretch as far as the eye can see lakes, waterfalls, sequoias and monoliths that are made out of granite. These granites are called half Dome and El Capitan.

Believe it or not, Yosemite has been designated as ninety five percent authentic wilderness.
Another US treasure found on a sixty three cent stamp is Utah’s Bryce Canyon. These stamps are all part of the Scenic Landscapes in America released by the US Postal Service.

The canyon is beautifully photographed by Tom Till from the city of Moab, Utah. Thanks to erosion, the Utah landscape developed spires now called as whimsical-looking hoodoos. Bryce Canyon was recognized nationally as a monument in 1923.
