Gauges

Gauges are what divers rely on for a safe dive, relying on them to monitor depth, time and air consumption. The depth and time are important to keep track of nitrogen and air management, in order to know how much air is remaining, and when they should begin a safe ascent. Other than with a gauge, time can also be tracked using a diving watch.
A scuba tank pressure gauge may be the only console on a wrist computer. For a full console a standard gauge is the choice to be made, with the single console there is one piece of equipment that attaches to the tank and shows the depth and tank pressure. Some are encased in rubber, such as a scuba pro gauge boot.

While this is the basic model, gauges can be more complex and will have more than two dials and include a compass, timer, temperature gauge and other instruments may be necessary or desired. For complete manageability most consoles can be disassembled and put back together in a different way to help the particular diver, as not every piece of equipment is perfect for every diver – there are often issue that may be unique to one but not the other.

Gauges are essential as it is vital to stop diving while there is air still in the tank – this is an obvious choice and most needed piece of information, despite having a gauge having a person to monitor the dive is also important.

To accommodate all divers, scuba gauges come in both metric and imperial units. Most American made gauges use imperial units, no matter the style preferred it has no effect on the quality of the device.
Scuba gauge size can be beneficial when a smaller unit is needed or with compact space. With a mini pressure gauge the low profile pressure gauge with low drags and is light weight with a bright dial in a rubber boot.

A submersible pressure gauge is a diving instrument and is available on mechanical or digital form showing the air pressure remaining in the air tank.

A wireless pressure gauge is often integrated into the diving regulator. These are several types of SPGs, such as the standard type – consisting of an analogue gauge that is hand held and displays the pressure range with a pointer over the dial. In addition, some standard types can include a compass, dive computer and depth gauge all in a rubber or plastic console.
