A Look at Scuba Wet Suits

Scuba wet suits were not taken seriously until World War II and the advent of Navy Frogmen (SEALs) who became one of America’s most effective weapons of the war. On any kind of measurable basis, costs of operations versus costs of effectiveness, man-to-man, or overall kill ratios, the SEALs exceeded expectations on any level. Once recognized, the military put a much time and money into improving the effectiveness of its frogmen. That meant improving the design, effectiveness and durability of wet suits.

There is a controversy that developed at the time over whether or not wet suits had to remain dry. Sounds like a set up for a joke but it’s not. All underwater, rubberized protective outfits are called wetsuits. The controversy was over whether heat loss from the diver’s body could be controlled better if the wetsuit kept his skin dry or not. It was Hugh Bradner who is credited with the first wet suit in 1952. Mr. Bradner was actually working as a physicist at UC Berkeley’s radiation laboratory where he was testing the reflections of shock waves on unicellular material and was invited to attend a Swimmer’s Symposium. His concept was that the diver’s skin does not have to stay dry to prevent heat loss if the thermal insulation used in the wet suit was obtained by air entrapped in the material of the suit.

With the French invention of the Aqua-Lung, Self Contained Underwater Breathing Apparatus (SCUBA) was used in the war and afterwards spawned investigative teams exploring the ocean’s many mysteries. As soon as this began, the pressing need for wetsuits was made painfully obvious by the divers suffering from hypothermia after only a few dives. The divers tried everything from greased long johns to leftover Air Force survival suits, and the Bradner wet suit. Bradner was the first to use a unicellular material similar to the type he was working with in the radiation laboratory in his wet suit. The material came from a company called Rubatex and was called Neoprene and the original model for today’s high-tech, three-level wet suit was born.

A Look At Roulette Gambling

For the novice gambler, roulette gambling seems like a very difficult task to learn. It is true that learning the strategies used by pros can take years of experience to master, but you can find many sources online that outline the basics of roulette gambling. Just keep in mind that it takes a while to become a master gambler and to pace yourself.

Basically, you use chips to place your bets on a variety of number and colors on the roulette table. The Croupier (dealer) spins the wheel and a number and color is chosen. As the wheel spins, a small ball rolls around the wheel and lands on a destination. This is just an example of the basics of roulette gambling.

Roulette gambling can be as simple as placing a bet and watching the wheel spin. Winning in roulette gambling is a combination of strategy, odds and luck. You will not win every round; knowing the odds of the game can greatly influence your success in roulette gambling. Practice does not necessarily make perfect in roulette, although the more you play and the more experienced you become, the better you will be at gauging the odds.

You can always try roulette gambling at an online venue to begin with. Many websites offer free roulette gambling and this might be a great way to learn the game and test your abilities. As you feel more comfortable with the game, you may decide to play at a casino or at an online venue that is pay-to-play. Roulette can be a fun and exciting game with the potential for great payouts.

A Look at Roman Seraphim Angels

Roman, Inc. is a giftware and decorative accessories distribution company most famous for its Seraphim Classics Collection of angels, as well as for its Fontanini Heirloom Nativities line of religious figurines. Begun in 1963 with $500 and a station wagon full of giftware, Roman now stands as one of the largest privately owned companies in the giftware and decorative accessories industry. Roman seraphim angels have garnered sixteen of the most coveted collectibles awards by Collectors Edition, the National Association of Limited Edition Dealers, and a host of other trade organizations. Even though Roman’s Seraphim Classics Collection is a relative newcomer to the world of porcelain figurines, it is today seen as the standard in excellence.

Seraphim Classics

The Seraphim Classics Collection is the most popular line in the history of angel figurines. They are considered the best and most beautiful representations of angels. They were first introduced in 1994, and in 1995 the first limited editions appeared. Since then, the Seraphim Classics Collection has garnered all of the most coveted awards in the collectibles industry for their unparalleled craftsmanship.

Master Sculptor Gaylord Ho designs all Seraphim Classics angels, sculpts them in clay, and creates the first molds, from which all of the figurines for that model will be reproduced. A handpicked army of highly trained artisans work together to reproduce the angel from the mold. Gaylord Ho oversees the entire reproduction process. Gaylord Ho, ensuring nearly perfect consistency, personally inspects each and every Seraphim Classics angel that comes off the line.

In addition to the joy of owning a figurine of high intrinsic and monetary value, collectors like knowing that their purchase is going towards a worthy cause. Each year, Roman donates tens of thousands of dollars to such charitable organizations as The Sunshine Foundation, the American Cancer Society, and the American Diabetes Association.

A Look at Marble Chess Sets

Marble is considered to be one of the great building materials in existence. For many centuries it has been used in the construction of buildings ranging from monuments, to temples, to palaces. Marble is sturdy as well as beautiful and can be carved into nearly any shape. The artist’s imagination provides the only limitation when using marble as a medium for a chess set.

Marble chess sets are also among the most beautiful. They are expertly crafted because the pieces are carved individually and often with extremely fine detail. Marble chess sets can come in a variety of colors but the most common combination is black and white. Black and tan, green and white, and red and white are just three of the unique color combinations also available. The marble itself looks stunning with its rich color, fine grain, and beautiful natural swirls. Marble chess sets often look like miniature monuments.

Many people purchase marble chess sets as decoration. They buy the set in colors that compliment the rest of the room and leave the set displayed on a table or pedestal. This is a good option for people looking for a unique way to show their appreciation for chess while adding character and class to a room.

However, marble chess sets are not just for decoration. The pieces are sturdy and heavy enough that they will not break except under extreme conditions. Marble chess sets are weighted to insure that the pieces are well balanced and will not fall over. The marble chessboards are also heavy enough so they can be used outside.

Marble chess sets are beautiful as well as functional. They look like miniature sculptures and are designed for play as well as for their appearance. A fine marble chess set is perfect for both decoration and regular use.

A Look at Ivory Chess Sets

Ivory chess sets have a long and distinguished history, going back nearly to the advent of the game itself. Ivory has been used for many centuries in the construction of chess sets. Some of the earliest chess pieces still in existence are made of ivory.

The British Museum displays a few ivory chess pieces from the 7th and

8th centuries found in modern day Uzbekistan. These ancient chess pieces are in a different form than modern day chess pieces because they come from a time when chess was primarily an Islamic game. The pieces had a much different appearance because they reflected a different society. In the 19th century, Nathaniel Cook and John Jaques created the first set of Staunton chess pieces out of ivory. The Staunton style of chess pieces became the standard that is still in use today.

Ivory is not nearly as common today as it was hundreds of years ago when historical ivory chess sets were made. Now, ivory chess sets are usually only for collectors. Vintage ivory chess sets can sell for many thousands of dollars, while new ivory chess sets rarely sell for under $900. New Ivory chess sets are extremely rare because ivory is much harder to come by. Though ivory was once commonly used in the construction of many objects, it is now rarely used due to animal rights issues and the advent of plastic.

One main reason why ivory is rare now is because many people object to animals such as elephants and mammoths being killed in order to cultivate the ivory from their teeth and tusks. Imitation ivory is a good modern alternative because it is much less expensive and does not use any animal parts.

A Guide to Discount RV Rentals

RVs are a unique way to travel with no hotels or crowded airports. It’s just you, America’s highways, and anything you want to see. Owning an RV, however, can cost hundreds of thousands of dollars. A cheaper alternative is to rent an RV. This is even a cost-effective way to sample different RVs before purchasing one of your own.

But renting an RV can still be expensive. Many companies charge a flat day rate on top of fees for additional miles. Plus there’s insurance, supplies, and a security deposit that is often not refunded in full, if at all.

Fortunately, there are ways to reduce the cost of renting an RV. One of the simplest ways is to rent an RV during the off-season. The weather may not be as warm, but you will probably save hundreds of dollars. Rental agencies offer discounts up to 70-percent during the off-season. Plus, you will travel without a swarm of other tourists.

Many Web sites also provide discount RV rental coupons. Search around to find a deal.

The most popularly rented RV is the class-C motor home. It can sleep six to nine people and has a modern kitchen. If you can go for a smaller motor home, maybe even one that’s a little more rustic, you will be sure to save money. Don’t go for the TV and DVD player. Also, comparison-price with rental agencies outside major cities. You may get a cheaper price.

One simple way to get a discount RV rental is to buy your time in bulk. You get a cheaper rate when you travel for more days. Many RV rental agencies also charge less the sooner you book your RV. So plan ahead!

If you plan on renting an RV frequently or stopping at lots of campgrounds, it may be cost-effective to join a discount camping club like the Happy Camper RV Club that gives up to a 50-percent discount at many camping sites.

A Guide to Underwater Cameras

There are two types of underwater camera systems: an “amphibious” camera, which is a self-contained waterproof system, and an SLR land camera with waterproof housing. Amphibious systems are small, compact, and easy to travel with, while SLRs offer more advanced features, such as auto-focus, advanced exposure control, and through-the-lens viewing.

The “amphibious” cameras are probably best for those of you who want a simple, easy-to-use point-and-shoot camera. Amphibious systems usually have a built-in lens and they will take pictures on land as well as underwater. They also have an automatic film load and advance and are generally compact, lightweight, and rugged.

If you are a more serious photographer and want the advantages of a single-lens reflex camera you will probably be happier with a land camera in waterproof underwater housing.

As a new underwater photographer you need to know the difference between taking pictures on land and underwater. The difference is what you are shooting through to take the picture. Air is transparent, whereas water is not. Light does not travel in a straight path underwater like it does in air. Water is denser and it includes particles of sand, plankton, and other debris which scatter, reflect, and absorb light.

You should know that all your underwater equipment needs and requires special care. Salt, sun, dirt and improper storage can damage a camera. Even though all your new stuff is made from rugged materials built for underwater use, it still needs to be rinsed in fresh water after every use. Saltwater should never be allowed to dry on the joints of the controls and metal fittings. Salt is your system’s number one enemy. Do not rinse with a hose. The high pressure may actually force salt crystals and sand into crevices. Use only soft lens tissues or photographic lens cloths on the lenses.

The most important thing you need to know about your underwater camera care is how to clean and lubricate the O-ring after every use. The O-Ring creates a watertight seal to protect your equipment from water, and so it is very important. The seal must be flawless— with no scratches, cuts, sand, hair – nothing on its surface. If it is not, the underwater photo equipment will be ruined. Water must be kept out! When in doubt about the sealing capability of an O-ring, always throw it out and replace with a new one.

Both your camera and your flash will need a watertight housing. You can use a flash fill-in to brighten underwater subjects at close range. Even with large flash units, though, light does not extend beyond 12 feet. The maximum effective distance of most flashes is four to five feet. Subjects farther away will not appear very colorful. Don’t forget you need to wait for your flash to recycle.

Assess conditions underwater before you dive and set aperture and shutter speed before entering the water.

The best time to take pictures without using a flashgun is between 11 a.m. and 2 p.m., when the sun is overhead. To capture sunrays with the subject in silhouette, face the sun. Close-up shots of fish are best taken at night–the fish are sleepy and not as active

Shallow water near steep rocky shorelines, coral reefs and atolls, and areas near tidal streams are great places to photograph sea-life.

A Guide to Triathlon Wet Suits

Triathlon wet suits are designed with state-of-the-art materials to help athletes get in and out of the water quickly, efficiently and of course, to keep the wearer warm. Triathlon wet suits are much more than the normal wet suit employed by divers simply to slow heat loss underwater and keep warm. Designed specifically for athletic competition, their first priority is to keep a competitive swimmer on top of the water, reducing drag and stalling muscle fatigue, enabling the swimmer to race faster and for longer periods of time.

Furthermore, the rubber used on the outside of the wet suit is of the slickest and most slippery materials possible to emulate the scales of a fish as closely as possible. The manufacturing technology employed in creating these wet suits has been a bone of contention between athletes and committee members because they reduce the difference between weaker swimmers and stronger swimmers, not only in speed, but also in all-around efficiency.

Because the triathlon wet suit enables a competitor to spend less energy on the first leg of the competition, he or she is able to reserve energy for the other two legs of the process. This can be a huge edge over the rest of the field, assuming of course, that you are not all wearing the same suits.

To begin with, the rubber used in most of these wet suits, regardless of the brand name featured, comes from one supplier – the world-famous, Japanese rubber manufacturer, Yamamoto. There is an important difference in the thickness of the rubber used in each and every different brand name of wet suit produced. Some manufacturers opt for the 2mm thickness, going towards producing a suit that weighs less and subsequently feels lighter to the user and is more flexible.

Other manufacturers go with the thicker rubber, up to 5mm thick, following the rule of thumb that shows that the thicker the rubber used, the more buoyant the suit will be and ultimately, even though it weighs more, will save the user more energy. In the end, it’s the swimmer himself who must decide which option best suits his style.

A Guide to Surfing Wet Suits

Surfing wetsuits are a breed unto themselves. To begin with, there are cool, surfer-dude designations used to describe the different styles of surfing wet suits.

The first is the spring suit which has short legs and short arms and is used to keep the upper body warm and has a thickness of materials of about 2mm. Short Johns are like spring suits but without the sleeves and are also usually 2mm thick. Long Johns have full-length legs and are mostly about 2mm thick. Full Suits are self-explanatory, the most commonly used — especially in colder waters — whose thickness is determined by the temperature of the water the surfer usually finds himself in.

Another difference in surfing wet suits is that many have two layers of material and the area under the arms is thinner than the rest allowing for easier arm movements critical to performing well while surfing. Furthermore, it is common for surfers to add an additional spandex suit underneath their wetsuits if they venture into cooler waters.

Surfing wet suits need to be more flexible in the upper torso and shoulder areas than diving wet suits to make the balancing and control contortions of the surfer easier. Especially sensitive are the knee areas as the surfer is constantly shifting his weight to maintain his balance.

Unless the knee areas move easily and don’t stretch during this movement they will inhibit the surfer and cause the suit to crack with wear at the knees over time. Because of the extreme physicality involved with the sport of surfing, the entire suit has to be manufactured with ease of movement and durability at its core.

Unlike other wetsuits, surfing wet suits don’t really care about thermal heat loss as much as diving suits. And because of the movement capability in the suit, gender specific manufacture is mandatory.
