Diving wetsuits – how do they keep you warm

Thursday, April 9th, 2009
by Clement C.

Is a wetsuits just a wetsuit and are all wetsuits made the same? Can you use a wetsuit that is meant for diving when you go swimming, surfing, windsurfing etc…? To some point you can, wetsuit is designed to keep you warm no matter for what sport it was originally meant. But on the other and wearing a wrong wetsuit can be limiting.

Two the most important things when it comes to wetsuits are warmth and fit. Warmth is decided by the thickness of the neoprene and it must be chosen by the location where the wetsuit will be used. Are you going swimming, snorkeling and diving in the tropics or are you going somewhere where the water is really cold? The other thing is the fit. If your wetsuit is to big it will not be warm no matter what, so the right fit is essential.

To take an informed decision, you need to understand how a wet suit works. Wet suits are basically made from neoprene, which is a highly porous material that contains millions of tiny little bubbles. Neoprene uses the nitrogen bubbles to create a barrier of air between the water around you and your body. A thin layer of water enters this barrier and gets heated up to your body temperature. As you reach greater depths, the suit starts getting looser as the Neoprene compresses against it self. When this happens, any water that may have entered, leaks out. At the end of the day, the wet suit must protect you and keep you warm.

Water temperatures keep changing. The change with the seasons, the change with the location… So you have to know when and where are you going to use your wetsuit to choose the right one. Wetsuits are also a bit different if you are a man or a woman.

Women should always get a little warmer wetsuit than a man for the same water temperature. Why? Because womens body has comparatively more surface area then mens body. This is why women get cold faster. Also – a general rule is that a warmer wetsuit is more practical since if you feel warm you can always let some cold water in to cool you down but if you feel cold there is not much that you can do.

The other thing to keep in mind is that a two-piece wet suit is likely to keep you warmer than a one-piece wet suit. The two-piece wet suit has the benefit of double insulation around the groin and chest areas. However, double the insulation also leads to greater restriction in movement and greater buoyancy, which would require you to carry more lead, than you would have to in a one-piece suit of similar thickness.

Now that we have covered the thickness of your wetsuit in relation to the water temperature you need to focus on the fit. Wetsuit needs to fit you, if it is to big, it will fill with water and loose much of its insulation capabilities. Only the right thickness and the right fit will keep you warm and let you dive without the fear of cold.

A Basic Guide To Scuba Diving Gear

Friday, March 13th, 2009
by George Carlmon

When it comes to Scuba Diving the most important thing is the training that you have, the next most important thing to that is the gear that you will need to have. Everything that I will cover here will be essential if you plan on making some deep dives.

Let me start off with the scuba mask, they come in many different styles but they all serve the same purpose. Do not sell yourself short when purchasing a scuba mask, especially if you plan on doing some deep dives, your eyes wont take kind to the water pressure if the mask happens to crack or break.

Bouyancy compensators air in letting the diver going up, down, or just staying neutral in the water during a dive. They also provide the tank attachment, along with diving gauges and oxygen regulators. For divers they are referred to as a BC, and they are absolutely essential when it comes to diving.

Scuba Diving wetsuits will keep the body warm when you are going down on the deep dives, and also provide minimal protection from sharp objects. Most of them are made from neoprene, and the further you dive down the looser the wetsuit will get.

Scuba tanks are the life of your dive, and they come in two different main types, which are aluminum and steel. Most tanks are rented from scuba shops, as you will need a diving license to get them filled with oxygen, and also to rent them.

Swim fins, also known as flippers will also be needed for any diver. One cannot expect good thrust in the water with their feet alone, this is why the long runner swim fins are needed to aid the diver to move through the water efficiently.

Diving computers will let you know a large range of data that you need to know when on a dive. Some of the things that dive computers will tell you are water temperature, depth, how much air is in the tank, a decompression meter, how fast you can safely ascent, along with many other things. Dive computers can be worn as a watch or attached to your BC.

Dive flags, reels and ropes, gloves, knives, weight belts, gauges, belts and bags are also necessities that the scuba diver will need. Along with all of these tools the diver will also need to be efficiently trained through either a diving school or accredited diving courses.

How To Ensure Safe Scuba Diving

Friday, March 13th, 2009
by Andy Krolov

Learning how to scuba dive is absolutely essential if you want to go into the deepest of oceans to experience underwater sights. During the process of doing so, it will entail having the necessary scuba equipment to facilitate this purpose and to stay underwater longer than what a human is capable of himself.

As a sport, Scuba Diving is one of the best forms available for anyone who wants to get fit, strong and healthy. This is because you involve the whole body when diving, which is more efficient than many other sports. The cream on top comes from being able to witness the wondrous underwater sights that come along with doing it.

However, Scuba Diving has its associated dangers along with it. There are some risks that one will have to understand and learn to avoid when participating in the activity. It also makes things easier when you realize that most accidents suffered on the sport are often mistakes made by the victims themselves.

The first thing to keep in mind on any diving trip is to observe all safety precautions and aspects of the sport. It might be so obvious to many that they simply ignore the danger they might put themselves in. Many take it for granted and do not even live to regret it in the end.

Many scuba divers attempt to do so without having received sufficient training. This is despite the legal requirement for one to have undergone many hours of training and certification before being allowed to go on trips. If you have considered doing the same, it would be advisable to think otherwise. Enroll yourself in a reputable Scuba Diving school and learn how to do so properly before setting off into the deeper waters.

For any sport with considerable risks, one must ensure that the equipment to be used is without faults. There is a need to maintain and check your own equipment prior to use each time. If you rent the equipment on trips, it would be prudent to check that they are workable before deciding on the final rental.

One of the most dangerous situations that you can get yourself into with faulty scuba gear is that of experiencing the bends. This is a condition whereby nitrogen in your bloodstream accumulates and quickly forms air bubbles which might cause death. If your scuba tank is not working properly, it could lead to such a condition even if you were to ascend to the surface slowly.

Ensuring your own safety is always of utmost importance in any activity. It prolongs your lifespan and allows you to continue enjoying your favorite activity rather than curtailing it through injury or even death. Therefore it is only for your own good to go through the necessary safety precautions of which a few have been outlined above.

When in Australia, Do What Australians Do, Scuba Dive

Saturday, March 7th, 2009

Scuba Diving is a fabulous hobby. It is fun, relaxing and very educational.  Scuba Diving offers people the opportunity to see what life is like below the water in lakes, and oceans. Scuba is an acronym that stands for self contained underwater breathing apparatus .

Not only is Scuba Diving used for recreation, it serves many purpose such as military, scientific inquiry, and even search and rescue. During summer, Scuba Diving is not to be missed in warm countries like Thailand, Egypt, and Australia. The reason is pretty clear: Scuba Diving is becoming more and more popular because people are realising just how fun and easy it really is.

Scuba Diving can also offer many different new experiences according to the place in which you practice it. But, not all places offer the best under water sight than the waters of Australia; it’s really a must see for beginners. Scuba Diving is one of the best sports and past times you can do, so learn more and join us in a whole new under water world. Scuba Diving can also be a very relaxing sport and in many places it’s very beginner friendly. Many dive sites are accessible (under the care of an instructor) after a short briefing and training dive. If you are considering Scuba Diving in Australia, my advise to you as a Scuba Diving Instructor is to try Scuba Diving in Sydney. For sure the Australian capital is one of the best hidden secrets  of the Scuba Diving community from down under.

When you consider diving in this amazing location of the word, divers have the opportunity to swim with amberjack, tuna, blue gropppers,  as tropical including butterfly fish, queen angelfish and a variety of damsels, chromis and blennies.  So if you are considering to travel around the world and want to have some serious and great diving, checking Sydney must be in your top list of things to do.

Scuba Diving Destination of the year: Fiji

Friday, March 6th, 2009
by Gordon Shuber

For a long time now you have wanted to discover the beauty and the mystery of the deep. Maybe that is the main reason why you signed up into Scuba Diving, joined a club and earned money relentlessly just so you can have enough to spend for diving trips. And if you are into underwater photography, maybe you want to capture such magnificent views, like the ones that you have seen in photographs from books and nature shows shown on television.

Well, to help you get what you are looking for, it is best to start by choosing first a Scuba Diving destination”a place thats guaranteed to give you front row seats to natures grand display of marine art. One of the top destinations travel agencies and other divers can recommend”wherever they are in the world”is the Fiji Islands.

Found somewhere between the Australian continent and the Tahiti Islands, the Fiji Islands is considered to be a haven for sightseeing and nature loving fanatics. The islands are scattered throughout the South Pacific Ocean, and is also known to be a place of friendship, due to the warm hospitality offered by its locals.

Though Fiji islands is made up of 322 islands, roughly a hundred of them are inhabited. The islands developed out of the vast coral reefs that inhabit this part of the world. Because of that, Scuba Diving enthusiasts refers to the islands as the Soft Coral Capital of the World.

It is a known fact that fishes and other marine animals flock to the coral reefs for shelter and food. And since the islands is literally an island made out of coral reefs, scuba divers and snorkelers alike can expect a wide variety of marine life”each with its own set of colors and other wonderful eye candies.

The turquoise-colored waters are also known for its clear vision it provides. The islands being situated near the equator helps bring about the possibility of seeing what is found beneath the waters even from just the surface. And if you are the type that loves warmth and sunshine, then the Fiji Islands will have to top your list of vacation destinations.

If you love photography, then the high visibility which allows you to see what is found beneath for many meters can be captured by your own camera even without diving underwater, thus you dont have to secure your own underwater camera. But the best way to capture such wonderful sights indeed is to suit up for Scuba Diving, bring along your underwater camera and shoot away. Going under the surface helps you to be near the various species that lurks within the reefs, like the colorful clown and butterfly fish, sharks, and sea anemones. Being near them not only gives you the best shots, but also allows you to study them in their natural habitat up close.

Even though the sights you get to see in this place sounds expensive, the Fiji Islands is also known for its reasonable prices. In fact, many agree that Fiji is the best place to learn Scuba Diving because most of the dive shops there offer certification courses at relatively cheaper prices. Now thats great deal for a Scuba Diving destination!

The Importance of Wet Suits

Thursday, March 5th, 2009
by Ed J Price

The accessory that most symbolizes today’s scuba diver, apart from the fins, mask and tank, is the wetsuit. Wetsuits are usually made of a combination of neoprene rubber and synthetic fabrics. They have come a long way since the early days of suit pioneers such as the O’Neill Brothers Santa Cruz surf suits. The make-up of today’s wetsuits has evolved into a wide variety of fabric weaves, designs, colors and types of material densities. With the many brands that each offers their unique take on each part of the divers dress, consumers are spoiled for choice.

History

Wetsuits were first made from rubber skins and were worn to keep in heat and for skin protection. More advanced suits made of neoprene, whose cellular construction traps air and water to be heated better than simple rubber. These more advanced suits were made possible by early designs of the rubber suits. However, although neoprene is more flexible, the earlier versions of wetsuits made from it were easy to rip and very hard to put on, putting it on often required applying talcum powder to the inside of the suit. As several generations passed, new breakthrough lines such as the Sharkskin and Turtleskin brands added a whole new layer of nylon sheeting to the inner suit and a textured surface which increases strength and durability.

Modern wetsuits use combinations of Lycra or other synthetic materials to replace nylon sheeting. Some brands, such as the Pinnacle Aquatics lines, feature combinations of titanium weaves and natural Merino wool to increased durability, warmth and to reduce odors. These modern suits also use layers of thicker materials to protect sensitive spine and neck areas, and have reinforced knee and elbow pads to protect the diver against chafing against rocks and coral heads.

How They Work

There is one basic principle of the wetsuit; water flows into small pores of the neoprene foam of the suit where it is trapped, it is then warmed up by the body heat and energy of the diver. This layer of warm water then acts as a thermal suit by keeping the cold water from getting to the skin. Wetsuits are actually designed to let water come into contact with the skin, unlike the dry suits which are sealed to keep water out. When temperatures range from 40 to 60 degrees, the average dive temperature, wetsuits are preferably used because there are hardly any intense temperatures for the body to be protected from. Dry suits are used for low exceedingly low temperatures to protect the body from potential freezing.

Different Types of Wet Suits

There are many different types of wetsuits besides the well-known full suit. “Shorty” suits have full torsos, but do not cover the entire leg and arm areas. These suits are good for warm water conditions, where the main issue is maintaining body heat at greater depths. The “Farmer John” style (now less popular than in the late 80s when it was invented) has a thickened “pants” layer that goes up around the shoulders, but doesn’t cover the arms; this type is good for surfing applications where knee protection is important. In addition, there are now specialized “thin suits” for competition swimming and light dive applications; these suits offer streamlining and abrasion protection more than they do temperature control.

The Hoods

The hood is the next important accessory to a full wetsuit. Its important because over 25% of body heat is lost through the head. They are often made of similar materials to a wetsuit but are thicker to prevent loss of heat around such a sensitive area. Most of the hoods have long bibs that tuck within the neck of the wetsuit to protect against a gush of cold water down the neck.

The Booties

While some wetsuits have integrated “feet”, most use separate “booties” that are drawn up over the legs of the wetsuit. Booties are usually corrugated and reinforced to allow divers to stand or push off against the bottom or rough surfaces.

Wetsuit Gloves

The last important accessory. Gloves must not only protect against cold water, but also must stop sharp coral and rocks from damaging the skin. Gloves often have textured fingertips to help in handling gear or other objects during a dive.

Summing Up

Ever since its early primitive rubber casing days in the early 1950s, the wetsuit has come a long way. Wetsuits will continue advance and offer divers many new options for their diving experience with new materials and special computer-aided designs.

Diving Regulators

Thursday, February 12th, 2009
by Ed J Price

Whether you’re new to Scuba Diving or a diving nut, you want to be sure the scuba regulator you have is top notch. There are differences in any scuba regulator and tons to consider such as warm water regulators, cold-water models, and ones that will work for any dive. Let’s look at what’s new, what are musts for diving regulators, and what’s a surprising alternative.

What’s New in Regulators?

In 2008, we saw the technologically advanced carbon fiber regulator that was lightweight and claimed to be most wanted for years. Compact yet high in performance the carbon fiber regulator’s second stage case came in sixty-five percent lighter than it’s metal cousins-take a look at these, if for nothing else-your curiosity.

A regulator that became a star in the alternate inflator category is the Sherwood Gemini model. It has scored points with its ease for its breathing features and well designed and placed controls.Apart from its light weight and nitrox ready features, for moderate breathing rates at 132 feet and 165 feet, its rated as excellent.

What’s a Must in Regulators?

One of the most important things that divers look for in regulators is durability. Regulators like the Sherwood Oasis, a good warm water regulator, need to be tested for durability, service hours, annual servicing, corrosion issues and peak performance.Since the year 2005, there has been a fast increase in the advancement of diving regulators. However, like any good piece of equipment, you should follow the manufacturers recommended care procedures to ensure your model lasts.

The Blizzard, another Sherwood regulator model, is right for cold water dives. Its ability to keep moisture and icing out is only a small part of its many features. It also has a bubble deflector exhaust tee which is exclusive to only this model. It reduces the bubble size which is great for line of vision.

Another regulator by Sherwood is the SR1. It boasts a 360-degree swivel that works with both a yoke and DIN attachment. Its best for all-weather diving. This scuba regulator is one of the top picks for 2008 because it had it all.

Alternative Dive Regulators

The inflation regulator is extremely functional and is integrated into the power inflator. This replaces the traditional octopus hose. The small housings are geared to keep the regulators ergonomically correct. Because of this, it was tough to build. However, with today’s technology, they have built some pretty good ones. In the near future, you can expect to see more advancements in dive regulators.

The Bottom Line

We looked at lots of models of dive regulators and we connected most with the Sherwood products, perhaps because they’ve been at it a while. In any event, a regulator is key to your aqua-lung when diving, so be sure to take the time to talk and ask a lot of questions before you commit to buy. Prices can range from a low $200 to highs at $600 or more. Depending on how serious you are in your Scuba Diving, your sports store should be able to tell you which ones will perform well for you.
