Garmin Descent™ X10 Dive Computer

The Garmin Descent X10 dive computer is a rechargeable scuba diving computer for recreational divers who want clear, no-fuss dive data without paying for features they'll never use. It pairs a big 2.1″ sunlight-readable display with air and nitrox support, a 100 m depth rating and up to 50 hours of battery life in dive mode, all in a tough, lightweight case made from recycled ocean-bound plastic. Whether you're logging your first holiday dives or getting wet every weekend, the X10 keeps the essentials front and centre, then syncs your dives to the Garmin Dive app so you can relive them back on dry land.

Features:

• Large 2.1″ display: a 320 x 240 monochrome display that stays easy to read in bright sunlight, with a backlight you can set to come on with depth or at the press of a button.
• Multiple dive modes: single-gas scuba, gauge and apnea profiles, so one computer covers recreational scuba, bottom timer duty and freediving.
• Nitrox ready: supports air and nitrox from 21–40% O2 with PO2 settings up to 1.6.
• Bühlmann ZHL-16C with gradient factors: pick low, medium or high conservatism, or dial in your own gradient factors if you like to fine-tune.
• NDL Aware depth metrics: see in real time how a small change in depth affects your no-decompression limit, which is handy for squeezing out a little extra bottom time safely.
• Customisable safety stop: choose off, 3 minutes or 5 minutes, with deep stops available using custom gradient factors.
• Garmin Dive app sync: upload logs wirelessly, tag locations, track your gear usage and share your dives.
• Surface diver status widget: check surface interval, N2 loading, CNS, OTU and tissue compartment status at a glance.
• Eco-friendly build: the housing and bezel are made from 100% recycled ocean-bound plastic.
• Add a splash of colour: customise the look and protect the device with replaceable bezel guards available in 4 colours (sold separately).

Built for the Way You Dive

Who Is the Garmin Descent X10 For?

Ideal for:

• Newly qualified and beginner scuba divers who want an easy-to-read first dive computer
• Recreational divers on air or nitrox up to 40% O2
• Travelling divers who want long battery life and a rugged, lightweight unit
• Freedivers who want an apnea mode alongside their scuba dive computer
• Dive schools and centres that need rental-ready computers
• Divers wanting a reliable backup alongside a main computer

Not ideal for:

• Technical divers who need trimix or CCR support
• Divers who want tank pressure on their wrist, as the X10 isn't an air integrated dive computer
• Anyone wanting a full-colour display or a full-featured smartwatch

Diving Modes

The X10 covers the three modes most divers actually use. Single-gas scuba mode handles your normal recreational dives on air or nitrox, with a bottom gas and backup gas settings as listed by Garmin. Gauge mode turns it into a bottom timer if you prefer to plan your own dives or run tables. Apnea mode gives freedivers depth and timing on the same wrist computer. You can also set your conservatism, safety stop and alerts separately for each mode, so your freediving setup doesn't get in the way of your scuba one.

Air Integration

The Descent X10 is a standalone, wrist-mounted dive computer and doesn't support tank pressure transmitters, so there's no air integration. For many recreational divers that's perfectly fine: you keep an eye on your SPG as usual and let the X10 look after depth, time and decompression. If seeing your gas on your wrist matters to you, take a look at our air integrated dive computers.

Display & Usability

Garmin has put the screen first on this one. The 2.1″ display uses large text that stays readable in bright sunlight and in murky water, and the backlight can be configured so it works the way you want. Buttons are leakproof inductive buttons, there are custom dive data screens to set up your layout, and an ascent and descent rate indicator keeps you honest on the way up. After the dive, the Garmin Dive app (iPhone and Android) logs your entry and exit locations and stores up to 200 dives on the watch itself.

Battery & Connectivity

You get up to 50 hours of use in dive mode and up to 6 months in standby, on a rechargeable lithium-ion battery that charges with Garmin's proprietary plug charger. That's a full week of dive holiday and then some without reaching for the cable. Bluetooth® handles the link to your phone and the Garmin Dive app, so your dive log is up to date by the time you're back at the dive centre.
