There are many gauges on offer. There are various types of gauges on the market, including digital, analog and pneumofathometer versions. A gauge that is right for you is key to a safe dive. Also, calibrating your gauge is crucial for decompression safety, especially at high altitudes.
Analog gauges
An analog gauge for gauge diving is a tool that allows divers to determine the depth in the water. You can use them to indicate the depth by turning a needle around a graduated scale. These gauges are worn on the wrist or can be integrated into the dive computer. While they are more reliable and accurate than digital, the analog ones can be worn on the wrist or integrated into the dive computer. An analog gauge offers the advantage that you won't run low on batteries.
The gauge's face is easy to read. It comes with numerical increments of depth that range from 10' - 40' and 20'- 150'. It also has a pressure gauge. It displays pressure from 0 to 5000 psi. The screen displays reserve air and the green screen main air.
Digital models
Divers desire to be able dive deeper and for longer periods of time, but a digital gauge doesn't allow them to do that. The difference in pressure between the gauge and the ambient water can be affected by temperature changes. A mechanical gauge is more reliable than an electronic device. The gauge can keep track of your dive time, depth and will also calculate your Nitrogen retention to prevent you from getting decompression sickness.
There are two basic types digital gauge diving computers. The hose connection is a basic method that uses a hose. This hose connects the dive computer with the high-pressure port of the first stage. Wireless mode uses an electronic transmitter to communicate with the computer. This type is also available in console and wrist-mounted models.
Pneumofathometers
Pneumofathometers can be used to measure the depth of air that is supplied to divers. These devices measure the air pressure near the surface and then display the depth in feet (or metres). These devices were once mounted on a hand crank air pump, which supplied breathing air to the standard dive suit. The air supply was free-flow, with no back-pressure.
If you are interested in gauge diving, you should get a gauge with a range from 130 to 160 percent of your diving system's maximum operating pressure. This range should be adequate for systems that operate at 3,000psi.
Submersible pressure gauges
A submersible pressure gage (SPG), which allows scuba divers keep track of their pressure, is a device used by divers. It also displays the current depth and the direction the diver is moving. The SPG is usually attached to the regulator via a high-pressure hose. This arrangement allows the diver to minimize confusion about where the gauge is located and keeps it from getting lost. The SPG indicates the remaining air pressure, in pounds per sq inch. It can be used for air supply monitoring while diving.
Scubapro produces an oil-filled analog depth gauge with a Bourdon tube design that measures to a depth of 200 feet. It also comes with a C1 compass, which attaches to the console boot for more versatility. This gauge is ideal to beginners, as it is simple and straightforward to use.
Compass
Easy to read compass is the best for gauge diving. The compass should be large enough to be read underwater and be marked with the appropriate markings. Look for a compass bezel with compass headings that are grouped in 30-degree increments. Indicator marks appear every five degrees.
Side view windows are important for gauge diving. They allow the diver to see where the compass points. This allows the diver even in complete darkness to follow the course of the compass.
