You can track your dives using dive tables, a depth gauge and dive watch, but most scuba divers use a dive computer – it’s easier. A dive computer provides the real-time dive information you need to dive well.A dive computer takes depth and time information and applies it to a decompression model to track the dissolved nitrogen in your body during a dive. Your computer continuously tells you how much dive time you safely have remaining. Your computer combines a depth gauge, timer and sometimes a submersible pressure gauge (SPG) into a single, useful instrument. The majority of divers have a computer because it makes sense. Visit your PADI Dive Center or Resort to get more advice about dive computers.
There are many dive computer choices and you can find the right one with a little help from a dive professional at your local PADI Dive Center or Resort.
