Safety is the most important consideration for every Scuba diver. Even if you rent other Scuba diving accessories, it’s a good idea to own your own wrist dive computer so you know exactly how it works.
Wrist Dive Computer Features to Consider
Dive computers come in all shapes and sizes, from more basic options to truly innovative devices. While any basic dive computer can help you track your depth, time underwater, and recommended ascent rate, some wrist dive computers have extra safety and convenience features as well.
If you want help orienting yourself, you should consider buying a dive computer with a compass — especially when diving in more complex diving environments. Other popular features include freediving mode, audible alarms, downloadable dive logs, solar charging, heart rate monitoring, and hoseless-tank data integration.
Safety-Focused Brands You Can Rely On
Your dive computer can help you avoid emergency situations underwater. It’s always a good idea to select a wrist dive computer made by a well-known, reputable manufacturer. Brands like Suunto, Mares, Cressi, Aqualung, and Oceanic are revered in the diving world for their reliable and intuitive dive gear.
What Is a Dive Computer?
A dive computer is an important safety accessory for every Scuba diver. Dive computers track vital information as you dive, including current depth, duration of your dive, how much breathing air you have left, when to take decompression stops, water temperature, and recommended ascent rate.
Which Wrist Do You Wear a Dive Computer On?
You can choose to wear your dive computer where it feels most comfortable and natural, but many divers wear their dive computers on the right wrist. That keeps the left side free for operating BCD valves and hoses. If you wear a backup dive computer or you’re left handed, you should place it on the opposite wrist.
How Do Wrist Dive Computers Work?
Dive computers track your depth and Scuba dive duration to calculate safe dive limits for your time underwater. They calculate the no-decompression limits using an internal algorithm. Rather than relying on dive tables or making calculations as you go, your dive computer helps you stay safe and frees up your mind for other tasks.
How Many Dives Does a Dive Computer Last?
As long as you take good care of your dive computer and follow a strict maintenance schedule, the device should last for many years. You should plan to service your dive computer every 200 dives or every two years, whichever comes first. Check your model’s specifications for exact care suggestions.
