Are Dive Computers Worth Buying?

Wiki Article

Years ago, dive tables were how everyone dived. These days, nearly all divers dive with a wrist-mount computer and they should.

Your computer monitors your depth, bottom time, speed of ascent, and no-decompression limits in the moment. Tables can't do that. If you move between depths mid-dive, the computer recalculates. A table can't.

Wrist-mount computers are the most common buy at this point. They're small enough, readable underwater, and you'll use them as a daily watch too. Hose-mounted models are an option but less people pick them recommended site anymore.

Budget computers go for around a few hundred dollars and handle everything the average diver would need. Features include depth, dive time, no-deco limits, dive logging, and often a basic freedive function. The $500-800 range gets you wireless air monitoring, nicer readability, and more mix modes.

Something people forget is how the computer handles. Some models are more cautious than others. A conservative computer results in less no-deco time. Liberal settings give more time but at a thinner safety margin. It's not right or wrong. It's personal preference and your diving background.

Check with the staff at a local dive store who's used a few different models before buying. Good dive stores will have real-world feedback on what's good and what's hype. Decent dive shops put out buying guides and honest reviews on their websites as well
