Track Every Dive with Reliable, Feature-Packed Scuba Computers

Whether you're a beginner or an experienced diver, a reliable dive computer is one of the most important pieces of gear you can bring underwater. Scuba.com carries a wide selection of scuba dive computers to help you track your depth, time, nitrogen levels, and ascent rate—making each dive safer and easier to manage.

Why Use a Dive Computer?
Dive computers monitor critical data like dive duration, depth, ascent rate, and nitrogen absorption in real time. This allows you to extend your bottom time, make safe decompression stops, and minimize your risk of decompression sickness. They take the guesswork out of diving—no more manually calculating tables mid-dive.

Wrist and Console Dive Computers
Choose from a variety of styles, including:

Wrist dive computers that function like watches and are easy to glance at

Console dive computers that integrate with your pressure gauge

Hoseless and air-integrated models that connect wirelessly to your tank

Entry-level and advanced computers with customizable settings

Many of the best dive computers also include features like Bluetooth syncing, dive log storage, temperature sensors, digital compasses, and nitrox compatibility.

Trusted Dive Computer Brands
Scuba.com stocks top-rated dive computers from leading brands like Suunto, Scubapro, Aqualung, Oceanic, and more. These manufacturers are known for rugged construction, intuitive interfaces, and dive-ready reliability.

Plan Safer Dives and Reduce Risk
Dive computers are designed to reduce human error by giving you real-time data. They can alert you if you exceed safe ascent rates or miss decompression stops—and log your dives for later review. While they don’t replace dive tables for planning, they're a vital backup and a trusted guide once you're in the water.

How to Choose the Right Dive Computer
When shopping for a dive computer, consider your driving style, future goals, and gear setup. Look for:

Clear, easy-to-read displays

User-friendly controls, even with gloves

Compatibility with your air setup

Adjustable algorithms for different safety preferences

Upgrade options for tech and rebreather diving

Take the stress out of dive planning and stay informed underwater with a reliable scuba dive computer from Scuba.com. Browse our selection today and find the best model for your next adventure.
