Dive computers for beginners: what they show and which settings to use
A dive computer tracks your depth and time and calculates how long you can stay without decompression stops. It should clearly show current and maximum depth, dive time and no-stop and no-fly time. Algorithms differ in how conservative they are, so PADI advises newer divers to choose a more conservative computer — and DAN reminds divers that staying inside the limits lowers risk but doesn't remove it.

What should a dive computer show?
PADI lists maximum depth, current depth, dive time and no-fly/no-stop time — plus a backlight, which you'll want if something goes wrong.
Why do computers give different limits?
Each uses an algorithm with its own bias — more or fewer, longer or shorter stops. DAN notes divers using different computers can get different limits on the same dive.
Which settings should a beginner use?
A conservative one. PADI says the less experienced you are, the more conservative you want your computer — and divers more prone to decompression sickness should also favour conservative settings. DAN adds that risk rises the closer you dive to the limits.
Frequently asked questions
Do I need my own computer?
It's the most useful first purchase for many divers; rental computers are available too — ask us.
Can I follow my buddy's computer?
Every diver should have their own; profiles differ even between buddies.
