Most people who learn to scuba dive start the same way: in a pool, with rented gear, and an instructor reminding them to watch their depth and air. The dive computer on their wrist is supposed to make that easier, yet many entry-level models have small, hard-to-read screens and menus that feel built for experts. Garmin is aiming squarely at that gap. According to Garmin’s announcement on November 3, 2026, the new Descent X10 is a dedicated dive computer designed to put “critical dive information at a glance” on the wrists of divers at every level, and it comes with a feature built for the businesses that rent gear to them.
A dive computer built around readability
The centerpiece of the Descent X10 is its screen. Garmin says the device uses an always-on, high-contrast 2.1-inch backlit display with large text, intended to stay readable from harsh sunlight on a boat deck to the dimmer conditions underwater. Divers can see their depth, dive time, oxygen-related information and more without hunting through menus.
Susan Lyman, Garmin’s Vice President of Consumer Sales and Marketing, summed up the design goal in the release: “Clear, accessible dive data can make all the difference under water.” She added that the X10 is meant to help divers “stay aware and supported from their first class and beyond.”
Key features at a glance
Garmin lists a focused set of capabilities rather than a sprawling spec sheet:
- Multiple dive modes: scuba, apnea (breath-hold freediving) and gauge modes, each showing the most relevant data front and center. The device is rated to 10 ATM.
- Rechargeable battery: up to 50 hours of dive time per charge and up to six months in standby, according to Garmin.
- Garmin Dive app: dive logs upload automatically after each dive, and users can tag locations and track gear usage from their phone.
- Device simulator: pairing the computer with the Garmin Dive app lets divers simulate full dives and practice using the interface before they ever get wet.
- NDL Aware depth metrics: a Garmin feature that shows in real time how changing depth affects the no-decompression limit (NDL), the time a diver can stay at a given depth before needing staged decompression stops.
- Setup sharing: divers who carry a backup computer can sync settings across compatible Descent models.
The simulator stands out. For new divers, the hardest moment to learn a gadget is while managing buoyancy, breathing and a buddy at the same time. Rehearsing on dry land is a simple idea that could make the device less intimidating on day one.
Rental mode: a feature for dive shops
The most unusual part of this launch is aimed not at individual buyers but at dive schools, shops and charter operators. Garmin says the X10 includes a rental mode that lets businesses configure each computer to match a diver’s skill level and quickly reset it between customers.
That sounds small, but it addresses a real operational headache. Rental fleets get handed to a different person almost every day, and each diver may need different settings. A device that can be reset cleanly, and set up appropriately for a beginner or a more experienced guest, saves staff time and reduces the chance that a customer starts a dive with someone else’s configuration.
Garmin also ties rental mode to a cosmetic feature. New replaceable plastic bezel guards, sold separately in colors such as Amp Yellow, Aqua, Purple Iris and Black, add protection and personality, and the company notes that color-coding makes it easier for shops to keep track of rental inventory.
Design and materials
The X10 ships with a silicone band long enough to fit over a wetsuit and is compatible with Garmin’s optional QuickFit bands. On sustainability, Garmin says 100% of the housing and bezel are made from recycled ocean-bound plastics, a fitting choice for a product designed to be used in the sea.
Price and availability
Garmin says the Descent X10 is available now at a suggested retail price of $349.99, with more details on the Descent X10 product page. That positions it as the entry point to the Descent line, below the company’s smartwatch-style dive computers.
What it means
- For new divers: the X10 is a dedicated, readable dive computer at a lower price than Garmin’s premium dive watches, with a simulator that helps you learn it before your first open-water session.
- For dive businesses: rental mode and color-coded bezels turn a consumer gadget into fleet equipment that is easier to manage, which could make it attractive for schools and resorts standardizing their gear.
- For the wearables market: the launch shows how mature smartwatch makers are carving out specialized, single-purpose devices where clarity and reliability matter more than app stores and notifications.
- A reminder: a dive computer is a tool, not a substitute for proper training and certification. Garmin’s release positions the X10 as support for divers “from their first class,” not as a replacement for instruction.
The bottom line
The Descent X10 is not trying to be the most feature-packed dive computer on the market. Instead, Garmin has focused on the basics that matter most underwater: a big, bright screen, sensible dive modes, long battery life and a phone app that handles the logbook. The rental mode is the clever twist, recognizing that many people’s first dive computer is one they borrow. If dive shops adopt it, a lot of new divers may meet Garmin long before they buy a computer of their own.
