Garmin has introduced the Descent X10, a new dedicated dive computer designed to give scuba divers and freedivers easy access to essential underwater information. Priced at $349.99, the device features a large 2.1-inch display, multiple dive modes, up to 50 hours of dive time and smartphone connectivity through the Garmin Dive app.

Announced on November 3, 2026, the Descent X10 is designed for divers of different experience levels, from beginners taking their first diving lessons to experienced underwater explorers. It also introduces a rental mode intended to make the device easier for dive shops, schools and charter operators to configure and reuse.

Garmin Descent X10 features a large, easy-to-read display

One of the main highlights of the Descent X10 is its 2.1-inch, always-on display. Garmin says the high-contrast screen, large text and backlight make important dive information easier to read in different lighting conditions, whether divers are on a sunlit boat or underwater.

The computer provides quick access to essential information, including depth, dive time and oxygen levels, helping users keep track of important measurements during their dives.

The Descent X10 supports three dedicated dive profiles: scuba, apnea and gauge. This gives divers access to different sets of information depending on the type of underwater activity they are pursuing.

The device also features Garmin’s NDL Aware depth metrics, which show how changes in depth can affect a diver’s no-decompression limit (NDL) in real time. This helps divers understand how their depth profile relates to the remaining time before a decompression obligation becomes relevant.

Garmin also includes a device simulator that works with the Garmin Dive app. Divers can use it to simulate dives and familiarize themselves with the computer before entering the water.

Up to 50 hours of dive time

Battery life is another important part of the Descent X10. Garmin claims the rechargeable battery can provide up to 50 hours of dive time on a single charge. In standby mode, the device can last up to six months.

For divers who maintain multiple compatible Descent computers, the new model also supports setup sharing. This allows users to synchronize settings across compatible devices, making it easier to maintain consistent configurations when using a backup dive computer.

After a dive, the Garmin Dive smartphone app can automatically upload dive logs, tag dive locations and track equipment usage. This gives users a way to review and organize their underwater activities without manually maintaining every record.

Designed for divers and equipment rental businesses

Garmin is also positioning the Descent X10 as an option for dive schools, rental shops and charter operators.

Its new rental mode allows businesses to configure computers according to individual divers’ skill levels and quickly reset the devices between users. This could make managing a collection of rental dive computers more straightforward, particularly for operators who serve multiple customers throughout the day.

The device comes with a silicone band designed to fit over a wetsuit and also supports optional Garmin QuickFit bands.

Garmin is offering separately sold, replaceable plastic bezel guards in four colors: Amp Yellow, Aqua, Purple Iris and Black. Besides adding a different look, the guards provide an additional layer of protection and can help rental businesses identify individual devices more easily.

Another notable design detail is the use of recycled materials. Garmin says 100% of the Descent X10’s housing and bezel are made from recycled ocean-bound plastics.

Garmin Descent X10 price and availability

The Garmin Descent X10 is available now in the US with a suggested retail price of $349.99. Buyers can find it through Amazon and Garmin’s official online store.

At this price, the Descent X10 brings together essential dive-computer functions, a large display, multiple dive profiles and dedicated rental-management features in a single device. Its combination of beginner-friendly accessibility and practical tools for diving businesses makes it an interesting addition to Garmin’s underwater adventure lineup.
