What Is The Best Dive Computer For Me?

Displaying dive times, depth and no decompression limits, a dive computer is one of the most important and often most advanced pieces of kit that any diver will own. Choosing the right one will not only help you to get more from your upcoming dives but also ensure that you can dive safely and stay underwater. Safe to say - finding the best dive computer is an important process for divers of all abilities.

However, with a huge range of styles and types of dive computers available, discovering which is the best for you can take time and effort. That’s why we’ve put together this handy guide to choosing the best dive computer, covering the factors you should consider when shopping around as well as our top picks of the best dive computers available right now. Read on and you’ll know the answer to the question ‘what dive computer should I buy’ in no time.

Factors To Consider When Choosing A New Dive Computer

Before looking at specific dive computer makes and models, it’s a good idea to take a step back and think about what you want to get from this important bit of kit. Contemplating your answers to the following factors should give you a clearer idea of exactly what kind of dive computer might be the best option for you.

Your Skill Level

The features a beginner diver needs from their dive computer will be quite different from those needed by an advanced or technical diver, so it’s important to understand your ability as a diver as you find the right dive computer for you. Perhaps you’re just about to start your PADI Open Water Training and are investing in your first dive computer, in which case you’ll want to look for a beginner-level bit of kit that prioritises usability with both air and nitrox functions. 

More advanced divers will want to look towards more advanced dive computers to match. Sometimes these will have bigger and/or brighter displays to make it easier to dissect information quickly and will typically offer air integration with wireless transmitters so that you can manage your gas seamlessly.

Compass Or No Compass?

All divers should be aware that a dive compass is another important piece of diving safety equipment, helping you to navigate effectively in the water. Many modern dive computers also include compass features, so it’s worth considering whether you prefer having a standalone compass or whether the best dive computer might be one that also doubles up with navigational functionality.
