No matter where you are in your freediving journey, having a reliable freediving computer (watch) is one of the best things you can do to become a better diver. An accurate freediving computer will tell you how deep and how long you dived, as well as provide safety features like suggested surface interval times and set off alarms once you’ve hit certain depths or a specific time underwater.

In this guide, we’ll cover the 11 best freediving computers on the market, why you should own a freediving computer, the key features to look for, and our in-depth reviews of each freedivine computer.

Why You Need a Freediving Computer

Freediving computers make you a safer diver.

As you become a better diver, you’ll be diving deeper and longer. Our brains are not great judges of time, so even though it might feel like you’ve taken a proper surface interval break – your timing is likely to be off. Since freediving computers display when you should break and when it’s okay to dive, you can focus on your breathe-up and relax knowing that your computer is keeping track of your time.

Freediving computers also have audible alarms that set at certain depths or once a specific amount of time has elapsed. Freedivers often become too relaxed in the water, and can overshoot their target depth and time that they should be spending on their dive. Sometimes, depending on visibility, 30 meters can feel like 10 meters or 10 meters can feel like 30 meters.  Setting an alarm helps you relax – you’ll know when it’s time to turn – and ensures that you stay on-target with your goals.

A freediving computer is also more accurate than relying on a marked rope as a depth gauge. Mismarked ropes have cost freedivers their lives. When you dive with a computer, you can verify that the rope is set up correctly, or check if the rope has stretched.

Freediving computers help you progress.

Freediving without a watch is like training for a marathon without mile markers. How do you know if you’re progressing, or how long you’re staying under? Our mental state, what we’ve eaten, our body temperature, and our health all play massive roles in how well we dive. There’s no way to know how long you dived or how deep without a gauge and clock.

Freediving computers keep a long-term record of your dives.

Most scuba divers keep a dive log that details where they dived, how deep, how long, what they saw, the gear they used, etc. Since freedivers usually complete many more dives per day than scuba divers, it’s not practical to keep a paper log. Many freediving computers let you upload your dive information to a PC, where you can keep track of hundreds – or even thousands – of dives at a time.

What to Look For in a Freediving Computer

Easy-to-read display

Beginner divers often make the mistake of buying a freediving computer that is more stylish than useful. Ideally, you want a display that is backlit, has easy-to-change functions, and large numbers. A freediving computer that isn’t backlit or has small numbers will be hard to read in low visibility and at deeper depths.

Your mind should be focused on the freedive, not if you are reading the correct numbers or not.

Note that some watch-style scuba diving computers with easy-to-read displays often are meant to be gauge mounted. They’re much less hydrodynamic and much heavier than strictly watch style dive computers.

Depth limits

How deep can your freediving watch go? Most recreational scuba divers will rarely go deeper than 30 meters because of decompression limits and risk of nitrogen narcosis. Freedivers, however, are capable of diving much deeper without these risks, even as recreational divers.

You’ll want a computer that can grow with your depth goals. There’s no point in buying a computer that only has a depth limit of 30 meters if your target goal is 35 meters. You’ll outgrow the computer too quickly.

Memory capability

Dive computers vary in how much dive information they can store. Most dive computers can keep a record of at least 100 dives. Since most dive computers offload their data to your PC, this might not be a major deciding factor unless you plan to go on a long trip where you won’t have access to a PC.

Scuba vs. freediving computers

If you’re a scuba diver, you might assume that your scuba dive computer can double as your freedive computer. This isn’t always the case. Many scuba-specific computers will sound an alarm if your ascent rate is too quick. Since freedivers can ascend as quickly as they want, often much faster than a scuba diver can, the alarm will sound nearly every dive. Obviously, a blaring alarm going off on your ascent isn’t exactly the best aid for relaxation.

Scuba diving computers also often have different triggers to when the dive starts. Freedivers want the most accurate data possible, so double check that your scuba diving computer is freediving compatible as well.

If you’re a freediver who also throws on a tank, it makes sense to buy a dual computer. One dual computer is sure to be better and cheaper than buying one computer for scuba, and a separate one for freediving.

Alarm settings

One key function in a freediving computer is an alarm. You can set an alarm to trigger at a certain depth or at a certain time. This helps keep you focused and signals where exactly you are in the dive.

Materials

Like with many things in life, you get what you pay for when it comes to buying a dive computer. You will want a wrist strap made of comfortable rubber or silicone. Metal or canvas is not a great choice for freedivers because the strap will not shrink under pressure like your body tends to. Budget computers tend to require more maintenance, might not have a warranty, and typically require a battery replacement at least once per year.
