Carrying proper diving gauges on every dive is common sense, and a range of devices we offer make monitoring dive parameters and air pressure simple. Gauges help divers stay within the no-decompression limit and ultimately avoid running out of air. Common types of gauges are Pressure Gauges, Depth Gauges, and Bottom Timers. Pressure gauges are attached to the regulator first stage by a high pressure rubber hose, and allow divers to read the air pressure in the scuba tank. Many divers use analog depth gauges that are arranged in a console. There is also the option for the pressure gauge to be combined with a depth gauge all in the same console. A bottom timer is a wrist or console-mounted device which digitally displays the diver's depth and dive time. Bottom timers make monitoring dive parameters easier, as all the information apart from the tank pressure, is found on one, easy-to-read display.
