BDC

(BCD) Buoyancy Control Device comes in many shapes and sizes for both men and women, but its main purpose is to help you control your buoyancy underwater and to provide a safe resting float at the surface.

Buoyancy is controlled with an single air bladder which is either positioned in the rear of the BCD or distributed (jacket-style). Rear lift BCDs allow A little more freedom of movement While diving but are harder to balance at the surface. The tank is secured to the BCD’s backpack with a strap and buckle. Backpacks can differ in their rigidity, but the main difference between backpacks is in their padding.

Cold water diving calls for the use of thick wetsuits, both of which require ample lead to offset their buoyancy, and a BC with enough lift capacity to compensate for the loss of that buoyancy at depth. In contrast, warm water diving requires that a BC have little more than a place to strap the tank, hang your hoses and enough lift to float the diver and minimal weight.

Additional features:

Material weights from 400 to 1000 Denier Nylon. The higher the number means the more abrasion resistant.
BCs offer a variety of shoulder and waist adjustments to help you custom fit the BC to your body.

Single and Dual Tank band configurations.

Quick releases on the shoulders make for easy removal on the deck or in an emergency.

Weight integrated – conveniently and comfortably allows you to carry some of your lead in your BCD. One should still wear a standard weight belt as well with the integrated BC to lower the weight in the unit and to add better balance. This also reduces staff fatigue lifting and retrieving after dives.
A thoughtful diver will remove the weight pockets and hand them up to the boat rather than expecting staff to lift a heavy unit.

Clips & pockets – positioned to provide convenient access to lights, knives, writing tablets, etc

Gauges

Scuba diving gauges and instruments are an essential part of any divers equipment, ensure your gauges are accurate by purchasing only major brand named products like those shown here. An accurate and reliable gauge can greatly enhance the safety and comfort of any dive. Analogue gauges featured here include: pressure gauges and depth gauges and compasses that all meet stringent safety and reliability standards. Diver Emporium offers only quality gauges that are easy to read even under adverse murky conditions.

Cameras

What do you want in an Underwater Camera? Being able to capture those fantastic images you see under water is most divers dream. If you have never taken underwater photos, buying a camera and learning how to use it can be scary. The following are the standards we use in selecting a camera for underwater use and it’s not as scary as it seems. Once you get the hang of it, it’s great fun.

Easy to use

Comfortable handling and easy one-button operation make your dive peaceful and enjoyable. So you can take impressive pictures with ease.

Easy to expand

Although most Cameras have a built-in flash, the ability to add an External Flash adds new dimensions to your pictures and is a must. Additional lenses so you can take close up with ease also is a must. Ability to expand to professional levels.

Ingenious Design

Cameras that perform equally well on land or in the sea, on boats or beaches. The inner Camera must remove easily so you can slip it conveniently into your shirt pocket.

Digital Cameras

A digital camera gives you the ability to see your pictures immediately , keep the pictures you like, delete those you don’t, and with photos in digital form you can edit them with a computer program, e-mail them to your friends and family, and burn them to photo CD’s. A digital camera is more expensive but you will never have to pay for film or processing.

Computers

Computers offer the diver a much more convenient way of monitoring decompression limits. Computers have invaded nearly every aspect of life and sport diving is no exception. Dive computers calculate nitrogen loading according to the diver’s depth and time, allowing a profile that is much more flexible than the square profiles provided by dive tables. Today’s computers display current depth, maximum depth, dive time, Water Temperature, Safe ascent and decent rates with visual and audible warnings, Surface Intervals, Dive planning, When its safe to fly in an airplane, Corrections for altitude, Air integrated units calculate you air consumption, and all record the dive information for recall later in a log book mode. Some computers require that the user pushes a button to activate while others activate automatically when you enter the water. Some are PC downloadable while others just store the log in memory. Some models have a Compass mounted. Computers go into a sleep mode or turn off if not used within a certain period of time. Most of today’s models allows for the diver to change his own batteries. computers also help you to maximize your bottom time by taking advantage of multilevel dive calculations. Perhaps most importantly, dive computers can decrease the risk of decompression sickness because they account for difficult (and sometimes impossible) manual calculations which result from yo-yo dives, multiple dives, quick ascents, varied physical effort and water temperatures. Computers can be mounted in a console, on the wrist in a wrist boot, or on the hose in a hose boot. How a computer is mounted is dependent on the divers preference and the computer’s configuration. Some models have a pressure gauge integrated into the unit.. These computers are able to display the amount of remaining air and calculate how long your air will last based on current breathing rate.

Nitrox computers offer all the same features as the air computers, but also allow the use of Oxygen Enriched Air. Once a diver’s Nitrox is programmed in the computer, decompression limits are adjusted accordingly. Warnings communicate to the diver nitrogen loading and oxygen limits for the present Nitrox at any given point of time during the dive.

It is wise to realize that today’s computers although very good are all based on mathematical models and are therefore not a perfect solution . Decompression Theory is not a defined science and is influenced by many variables. The future of computers is expanding rapidly and our future models will be able to program in a divers age, weight, sex, etc. all values which today’s models cannot do. Already we have computers that are visible in a heads up system that displays information in the divers mask. These units are very reliable. It is prudent to keep track and to even consider a redundant system so that if your computer fails or the batteries go down you can still collect the information you need and to calculate standard tables as well, as you use the convience of your computer.

Analog and Digital Gauges of today are very accurate and provide the necessary information needed to monitor air supply bottom times depths and navigation with compass. They come in single units to multiple configurations. Many are made in plastic cases and the better ones are still made in brass cases. They vary in the amount of depth units and psi units. Digital units require batteries. Some gauges are user adjustable.

Fins

Selection of the proper fin for the proper application is as important as choosing a good regulator. If you choose a fin that is not adequate to support the activity you are planning on doing you can increase the effort necessary to complete the task. If you choose a too forceful fin for your fitness level you can experience fatigue and cramping.

Masks

The Underwater environment provides a unique environment for our senses, especially the sense of sight. The function of the mask is to provide a window to Planet Ocean, by creating an air space between the diver’s eyes and the water.

Diver Emporium offers only the best masks available so you can focus on the specific features that meet your diving needs. When making your selection, consider the grade of skirt material (usually silicone), number of windows and special features like a purge valve. If you wear glasses or contacts we can have your exact prescription and or Bi-focal installed in any mask you select. Ask one of our Experts which features match your needs.

Due to the large selection of masks available, we have selected those that will fit 99% of faces. We have also listed them into separate pages by brand. We also have mask accessories and defog as well.

Regulators

Your scuba regulator is your most important piece of SCUBA equipment. This is your life support piece of equipment. Safety, Simplicity, Reliability & A Name You Can Trust. Click on the below links to view the quality equipment we offer you.

The job of the scuba regulator is to supply air to the diver at ambient pressure. The first stage of a scuba regulator attaches to the tank and reduces the pressure of the air in the tank to ambient pressure plus a preset intermediate pressure. The air is then sent down the hose to the second stage.

Features to consider when selecting a scuba regulator: Balanced vs. Unbalanced – a balanced regulator breathes the same at all depths while an unbalanced regulator is increasingly difficult to draw air from as you go deeper. All balanced regulators compensate for depth by equalizing the pressure on both sides of the air valve to the pressure of the surrounding water. The balanced regulator air valve essentially “floats” in an pressure chamber.

Most new scuba regulators provide two high pressure ports for pressure gauges and four low pressure ports for second stages, LP inflator hoses or dry suit hoses. Second stages offer external adjustments that can be made by the diver while diving to vary the performance of the regulator. The venturri assist is a two position adjustment that creates a venturri effect to optimize breathing performance and help prevent free flows at the surface. Another type of adjustment is the adjustable air flow knob or dial. This adjustment alters the flow rate to compensate for depth changes.

Diaphragm vs. Piston – refers to the mechanism that opens and closes the air valve in your first stage. Each represents a different design style. While neither style is necessarily better than the other, some prefer diaphragm-style regulators for their minimal moving parts.

Metal: Today’s scuba regulators come in a variety of metal configurations. The classic first stage construction is solid brass with a chrome covering. Now we have the entrance of the all new titanium models that offer less weight and 100% corrosion resistance. Second stages also come in a variety of metals and plastics. Brass and chrome second stages, Tri-metal, Titanium, Plastic, and Plastic-with Metal inserts for re-hydration of the air.

Snorkels

Totally Dry Snorkel

With state-of-the-art comfort, technology and design, plus unparalleled durability, our newly designed Dry snorkel clearly improves on our innovative past. H2Odssey- who introduced some of the diving’s first snorkel innovations – now offers new mouth-pieces designed to anatomically conform to the shape of your mouth. This gives you more comfort and more dive time. Plus, our patented “Flapper” valve keeps water out and makes clearing easier than ever.

Tanks

Using the correct cylinder is just as important to a divers success and safety as how they configure their gear. A diver may go to an enormous effort to insure every hose, reel and accessory is exactly right only to “drop the ball” by making the wrong cylinder choice. We bring you scuba cylinders from the leading tank manufacturers in the world – Luxfer and Faber – so you can not only get it done, but can get it done right. No tank is perfect for every diver or every diving situation, .We are a Authorized Seller for Luxfer & Faber scuba Cylinders offering the most complete selection of cylinders in the industry allowing you to choose what is best for your unique needs. Further we only sell new tanks in current hydro. You won’t ever receive a new tank from us with a hydro 2 years old. So watch out for some of those cheaper buys as your getting a less than new un-used tank.

Basic characteristics

Aluminum – a lightweight and inexpensive material that may produce a dramatic buoyancy shift from full to empty. This buoyancy shift, however, can be advantageous for divers wearing wetsuits. Because divers rarely carry a redundant buoyancy control device, a wetsuit clad diver could find them self unable to swim to the surface if wearing heavy steel tanks and their BCD failed. In contrast, a diver using an aluminum tank would be equipped with enough detachable weight to make an escape to the surface. Aluminum cylinders are the most commonly used tanks in recreational diving and are the choice of technical and cave divers for use as stage and decompression bottles. The average working pressure of aluminum cylinders is 3000 psi.

LP Steel – heavier than aluminum tanks they require lower working pressures while providing a larger gas capacity. When diving with these tanks less weight is needed, making them perfect for divers that use dry suits. The most popular tank for Nitrox and cave diving, they have a strong following among technical divers everywhere. The average working pressure is 2400 psi.

HP Steel – heavier than aluminum these cylinders use higher working pressures to provide a large capacity in a small size. Like their low pressure steel cousins less weight is needed with these tanks. A favorite with wreck divers along the East coast of the United States, the average working pressure is 3500 psi. Not recommended for Nitrox.

The Tank Specification link below lists all of the cylinders available from Diver Discount Catalog, thirty-two in all! This is the largest selection available from a single source. Specifications have been provided by the manufacturers to aid you in the selection of the prefect tanks for your needs.

All cylinders are provided with a single outlet valve and are prepared for Nitrox service, visually inspected and shipped with a current hydrostatic date. Cylinders are also available without valves upon request.

FABER is the leading manufacturer of steel scuba tanks in the world and is the market leader in Europe where diving with steel cylinders is the norm. Faber’s cylinders are manufactured from deep drawn Chromium Molybdenum steel plates to DOT and TC specifications. This process results in a light tank with the right buoyancy allowing the diver to reduce the amount of weight from their weight-belt. The interior of the cylinders are shot-blasted followed by their exclusive phosphatized coating which creates a perfectly cleaned internal surface, highly resistant to rust. The exterior of the cylinder is triple protected with zinc spraying, epoxy primer coat and polyurethane finish coat for durability. Abysmal Diving carries the most extensive selection of sizes starting with a 45 cubic foot all the way up to a 120 cubic foot cylinder. Faber cylinders are available in both 8 inch diameter LP 2400 psi rated cylinders as well as their compact 7.25 inch 3120 psi rated cylinder.

The difference between Pressure & Volume -One should note that the pressure of a tank is not a measure of the volume of a tank. For example, most aluminum tanks, from the smallest 13 Cu Ft. pony bottle to an 80 cu ft tank, have a fill pressure of 3000 psi. For a 13 cu ft bottle, this means at 3000 psi the tank contains 13 cu ft of air. For an 80 cu ft bottle this means at 3000 psi the tank contains 80 cu ft of air. Tanks come in different combinations of volumes and fill pressures but the cubic foot (cu ft) volume is the measure of how much air a tank holds at a specific pressure.

SPARE AIR

Spare Air is the preferred choice of both professional and sport divers for a very good reason: It saves lives.
