There are many types of gauges on the market. 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. It is important to calibrate your gauge at all altitudes for safety decompression.
Analog gauges
Divers can use analog gauges to gauge dive. They are able to measure the depth of the water. To indicate the depth, they use a needle that pivots around a graduated gauge. These gauges can be worn around the wrist or integrated into a dive computer. They are less accurate than digital gauges but more reliable than analog. An analog gauge has one advantage: you won't run out of batteries.
The gauge's display is easy to read. It has numerical increments of depth ranging from 10'-40' and 20’ to 150'. A pressure gauge is also available on the gauge. The gauge displays pressures from 0 to 5500 psi. The red screen is reserved air while the green screen is 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. Temperature fluctuations can alter the pressure difference between your gauge and the surrounding water. Fortunately, a mechanical gauge is much safer than an electronic gadget. 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 types of digital gauge dive computers. The hose approach is simple and uses a pipe to connect the diver's computer to the high pressure port at the top of the first stage. The wireless mode connects to the dive computer using an electronic transmitter attached at the first stage. This type can be used with console and wrist-mounted models.
Pneumofathometers
Pneumofathometers are devices used to gauge the depth of air supplied to a diver. These devices measure surface air pressure and indicate depth in meters or feet. These devices were used to be mounted on an air pump that provided breathing air for standard diving suits. The air supply was completely free-flowing, and there was 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 submersiblepressure gauge (SPG), allows divers to keep track and monitor their air pressure. It can also display the current depth and direction of the diver's movement. An SPG is typically attached to the regulator by a high-pressure line. This arrangement makes it easy for the diver to locate the gauge easily and prevents it from becoming lost. A SPG shows the remaining air pressure in pounds per square inch and is useful for monitoring your air supply while diving.
Scubapro's oil-filled analog depth meter features a Bourdon Tube design. It measures to a depth 200 feet. You can attach the C1 compasses to your console boot for additional versatility. This gauge is ideal to beginners, as it is simple and straightforward to use.
Compass
A compass that is easy-to-read is the best compass to use for gauge diving. It should be large enough for you to read underwater and with the correct markings. Look for a compasse with a bezel that includes indicator marks and compass headings.
Side view windows are important for gauge diving. They allow the diver to see where the compass points. This allows the diver to follow the compass' course even in complete darkness.
