Product FAQ

1. What Is a Dive Computer?

A dive computer is a tool, worn by a diver, to measure time and depth of dives. These are also called personal decompression computers or decompression meters.

2. What Are Dive Computers Used for?

Dive computers are primarily for avoiding decompression sickness. The best dive computers will integrate other features as well such as dive logs, dive planning, different gas capacities, and wireless or bluetooth capacities.

3. What Is the Best Dive Computer for Beginners?

If you are a beginner, choosing the best dive computer can be confusing. Try to focus on a dive computer that is safe, stable and reliable, yet not too expensive.

4. What Are the Best Dive Computers for Advanced Divers?

That is a complicated question to answer. Once you have been diving for a while, you will learn what features are important to you personally. We recommend waiting to invest in a more complex dive computer until you know what you need. Too many features can lead to confusion, which can be dangerous.

5. What Are the Best Dive Computers for Technical Needs?

Technical divers need dive computers that are durable, easy to read and reliable. Using a dive computer for technical diving is more about reliability and function and less about flashy features and fancy gadgets.
