Do You Need to Buy Your Own Dive Computer?

Years ago, dive tables were how everyone dived. Now, nearly all scuba divers dive with a dive computer and it makes sense.

A dive computer calculates your depth, time, speed of ascent, and no-decompression limits in the article moment. Tables give you a static plan. When you go shallower during a dive, it updates. Tables are set before you get in.

Wrist computers are the most common use now. These are compact, easy to read, and you can wear them as a watch between dives. Hose-mounted models are still around but fewer buyers choose them now.

Basic computers go for around $250-400 and cover everything the average diver requires. You get depth tracking, time, NDL, dive logging, and sometimes a basic apnea mode. Mid-range gets you transmitter compatibility, nicer screens, and additional gas compatibility.

Something new divers overlook is how the computer handles. Certain computers are more conservative than others. A cautious computer means reduced no-deco time. Looser ones give more time but at reduced safety margin. Both work. It's what you're comfortable with and your diving background.

Talk to the staff at a local dive store who's used multiple brands before buying. Good dive stores will offer real-world feedback on what works and what's marketing. Most good dive stores put out product guides and rundowns on their sites too
