Are Dive Computers Worth It?

Wiki Article

Years ago, dive tables were the standard. Today, the majority of divers use a dive computer and for good reason.

A dive computer calculates your depth, bottom time, ascent rate, and NDL in the moment. Dive tables are a fixed calculation. If you change depth mid-dive, it updates. Tables don't.

Wrist computers are what most people buy now. They're compact, easy to read, and you can wear them as a watch between dives. Console computers are an option but not as many buyers pick them now.

Entry-level computers run about $250-400 and do everything the average diver requires. Features include depth, bottom time, no-deco limits, dive logging, and usually a basic freedive function. Mid-range adds wireless air monitoring, nicer screens, and additional nitrox compatibility.

What buyers don't think about is conservatism look here settings. Certain algorithms are more cautious than others. A tighter algorithm gives you shorter bottom time. More aggressive settings extend time but at reduced buffer. It's not right or wrong. It comes down to your style and your diving background.

Worth talking to someone at a local dive store who dives with multiple brands before buying. Good dive stores will have a straight answer on what works versus what's just marketing. Decent dive shops publish buying guides and comparisons on their websites as well
