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. Your gauge must be calibrated at all times, especially when diving at high altitudes.
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 are worn on the wrist or can be integrated into the dive computer. While the analog gauges are more reliable than digital ones, they may not be as accurate. An analog gauge has one advantage: you won't run out of batteries.
The gauge's front is simple to read. It offers numerical increments in depth of 10'-40', 20'-40', and 20'-150'. The gauge also includes a pressure 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 want to dive long and deep. A digital gauge will not help them achieve this. The difference in pressure between the gauge and the ambient water can be affected by temperature changes. Fortunately, a mechanical gauge is much safer than an electronic gadget. A mechanical gauge is safer than an electronic gadget. It can track your dive time and depth as well as calculate your Nitrogen retention. This will help to prevent decompression illnesses.
There are two types of digital gauge dive computers. The hose technique is the simplest. It uses a hose for connecting the dive computer to a high-pressure port on stage 1. Wireless mode, however, connects the first stage with an electronic transmitter. You can also find this type of diving computer in console or wrist-mounted models.
Pneumofathometers
Pneumofathometers measure the depth of the air supply to a diver. These devices measure air pressure at the surface and then indicate 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.
For gauge diving, divers should buy a gauge that is between 130-160 percent of the maximum operating temperature of their diving system. For systems that operate at 3,000psi or higher, a gauge with this range will suffice.
Submersible pressure gauges
A submersible pressure gauge (SPG) is a device that allows scuba divers to keep track of their air pressure. It also displays the current depth and the direction the diver is moving. The SPG connects to the regulator using a high pressure line. This arrangement reduces confusion and prevents the regulator 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 manufactures an oil-filled, analog depth gauge. The Bourdon tube design measures down to 200 feet. You can attach the C1 compasses to your console boot for additional versatility. This gauge is great for beginners as it is simple to use.
Compass
The best compass for gauge diving is the one that is easy to read. It should have adequate markings to suit your needs and be large enough to be readable underwater. Look for a compasse with a bezel that includes indicator marks and compass headings.
A side view window is an important feature of a compass that allows gauge diving. It lets the diver see the direction in which the compass point. This allows the diver even in complete darkness to follow the course of the compass.
