Whether you are deep-water diving off the coast of Thailand or diving in the blue waters of the Gulf of Mexico, diving is a sport marked by adventure, beauty and just a little risk. It makes sense, too. Part of the thrill is seeing foreign, alien worlds that exist just under the surface of the water. These places have hardly been explored by people outside of the diving community, so every glimpse of this underwater world is like a snapshot of a faraway kingdom. Of course, seeing this beauty can be a risky endeavor, but the whole point of buying diving gear is to make your diving adventures more exciting and safer. Having one tool in particular at your disposal can change the diving game more than any other: your dive computer.

Choosing a dive computer can be difficult, however. Dive computers are complex, nuanced and detailed pieces of machinery to the point that even the most experienced divers need assistance when choosing and often perform massive amounts of research. Lucky for you, we’ve done most of that work for you. Here’s a brief cheat sheet detailing what to look for in a potential dive computer as well as the some of the top brands available.

Product FAQs

What Is a Dive Computer?

This isn’t the kind of computer you use at work, although it may be just as complicated. Dive computers are devices that scuba divers take on their dives either in the form of a small waterproof computer or more frequently in the form of a dive watch. These computers keep track of your dive to ensure you know where you are and stay safe at all times.

What Does a Dive Computer Do?

The submarine world is unlike the above-ground one. It’s fairly easy to become completely disoriented. Diving computers change all this by keeping track of your dive, logging your depth, direction, speed and other features. Additionally, dive computers are the easiest and most important way to prevent you from rising too quickly and getting decompression sickness.

Where Can You Buy Dive Computers?

Dive computers are available at nearly any scuba diving store, as well as hundreds of potential online options. Buying online may be the most convenient as you get a host of reviews and writeups to read for research but never have to leave your house to order your new dive computer.

How We Reviewed Diving Computers

To determine the top diving computers, we did a ton of research. We scoured the internet, reading customer reviews, consumer reports and information on various diving technologies in order to figure out in vivid detail the best diving computers for different divers. Plus, we also perused different diving computer websites and brand histories. That way we could calculate other metrics that may not be associated with the diving aspect of the computers such as shipping prices, availability or price ranges.

Overall Dive Computer Price Range

Dive computers can run the gamut in terms of prices. The lowest and most common prices tend to be in the $300-$450 range. At the more expensive end of the spectrum, dive computers can get as high as $1,000-$1,500. These more expensive ones often have more advanced statistics and complex abilities, giving you more advanced diving experience. At the same time these advanced abilities may be too complex and nuanced for a beginning diver. If you’re just getting into diving, a cheaper option might be more ideal.
