There are various types of gauges available on the market. There are various types of gauges on the market, including digital, analog and pneumofathometer versions. It is important to choose a gauge that suits your needs in order to ensure 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. You can use them to indicate the depth by turning a needle around a graduated scale. These gauges can either be worn on the wrist or integrated in the dive computer. They are less accurate than digital gauges but more reliable than analog. An advantage of an analog gauge over digital is the fact that you never run out.
The gauge's front is simple to read. The gauge has numerical increments that range from 10' to 40’ and 20' up to 150'. The gauge also includes a pressure gauge. It displays pressure from 0 to 5000 psi. A red screen indicates reserve air, while the green screen shows main air.
Digital models
Many divers desire to dive deep and stay there, but a digital gauge can't be used. Temperature changes can affect the pressure difference between the gauge's water and the ambient. A mechanical gauge can be safer than an electronics gadget. Not only will it keep track of your dive times and depth but also calculate Nitrogen retention, which can help prevent 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, on the contrary, attaches an electronic transmitter to the first stage to communicate to 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 surface air pressure and indicate depth in meters or feet. These devices were originally mounted on a hand-cranked pump that supplied breathing oxygen to the standard diving suit. The air supply was free flowing, 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 is sufficient for systems operating at 3,000 psi and more.
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 attached to regulators via a high-pressure pipe. This arrangement helps the diver avoid confusion and keeps the gauge from getting lost. An SPG displays the air pressure remaining in pounds per square inch. This is useful for monitoring air supply when diving.
Scubapro makes an oil-filled analog depth gauge that measures up to 200 feet. It has a Bourdon tube design and is oil-filled. The console boot can also be attached to it with the C1 compass. This gauge is perfect for beginners since it is simple to operate.
Compass
A compass that is easy-to-read is the best compass to use for gauge diving. The compass should be large enough to be read underwater and be marked with the appropriate markings. You will want a compass that has a bezel with indicator marks at every five degrees and compass headings in increments of 30 degrees.
Side view windows should be included in a compass used for gauge diving. This allows the diver to see which direction the compass is pointed. This allows the diver, even in total darkness, to follow the compass's course.
