Garmin Descent X10 – Dive Computer

Garmin Descent X10 is a modern dive computer designed for recreational divers, freedivers, and beginners who are passionate about the underwater world. It offers a clear overview of all important dive data on a large, 2.1" high-contrast display with permanent backlighting. Thanks to its simple controls, practical diving features, and durable construction, it is a reliable partner for exploring the underwater world.

Both the case and bezel are made from 100% recycled plastics sourced from coastal areas and aquatic environments. The Descent X10 thus combines functionality, durability, and a more environmentally conscious approach.

Large, Easy-to-Read Display

The dive computer is equipped with a large 2.1" monochrome MIP display with a resolution of 320 × 240 pixels. High contrast, large displayed data, and a constant backlight ensure good readability in direct sunlight and underwater. The font size can be adjusted to suit your needs.

Dive modes for various activities

The Garmin Descent X10 offers several dive profiles that allow you to customize the data display for a specific type of dive.

• Gauge Dive Mode: supports dives with a single breathing gas mixture.
• Nitrox: supports mixtures with 21–40% oxygen content.
• Apnea: a mode for freediving and breath-hold diving.
• Depth Gauge: displays basic depth and time data.

The computer uses the Bühlmann ZHL-16c decompression algorithm with gradient factors, which allows the diver to adjust the level of conservatism according to their needs.

NDL Aware – overview of the no-decompression limit

The NDL Aware feature monitors the effect of depth changes on the remaining no-decompression limit (NDL). It provides the diver with up-to-date information on how a change in depth can affect dive time without the need for decompression stops.

Alerts and Safety Features

For better situational awareness during a dive, the Descent X10 offers audible and vibration alerts. For example, it alerts the diver to ascent rate, PO2, OTU, NDL, or decompression limits. You can also set custom alarms based on depth or time.

• Audible and vibration alarms.
• Alerts for ascent and descent rates.
• PO2 and OTU monitoring.
• Alerts for exceeding NDL and decompression limits.
• Customizable safety stops.
• Automatic altitude adjustment.
• Time-to-fly indicator.
• Automatic dive start and end.

Garmin Dive – your dives always at your fingertips

Thanks to wireless Bluetooth connectivity, the computer can be paired with the Garmin Dive mobile app. Dive logs are automatically synced with the app, where you can view your dive history, tag dive sites, track dive gear usage, and analyze your underwater activities.

The internal memory can store a history of up to 200 dives. When paired with a compatible phone, you can also record the GPS location of your entry and exit points.

Also ideal for dive centers and rental shops

A special Rental Mode simplifies the use of the computer at dive centers and schools. It allows for quick reset of settings between users. Additionally, the settings-sharing feature allows you to synchronize configurations between compatible Garmin Descent computers.

Durable construction and long battery life

The case and bezel are made of fiber-reinforced polymer containing 100% recycled plastics sourced from aquatic environments. Chemically toughened glass protects the display, and waterproof capacitive buttons allow for comfortable operation even underwater.

The rechargeable lithium-ion battery provides up to 50 hours of runtime in dive mode and up to 6 months in standby mode.
