Garmin quatix Marine Smartwatches: Your Boat, On Your Wrist

The Garmin quatix is the only smartwatch purpose-built for boaters. It takes the hardware of Garmin's flagship fenix multisport watch, then connects it to your boat: chartplotter data streaming, autopilot control, Fusion-Link audio, trolling motor control, tide and anchor-drag alerts, sailing race tools and waypoint marking from anywhere on deck. Off the water it is a complete fenix-class fitness, health and navigation watch with a 40-meter dive rating, so one watch covers the helm, the gym, the trail and the reef.

The current lineup is the quatix 8 (announced June 2025, 47 mm and 51 mm AMOLED) and the quatix 8 Pro (announced January 2026, 47 mm AMOLED), which adds built-in inReach satellite and LTE connectivity for messaging, SOS and phone-free calling up to 50 miles offshore. At DiveCatalog.com we carry the quatix as an authorized Garmin dealer, with QuickFit 22 and 26 bands to match.

What the quatix Does on the Water

Boat data streaming. Pair with a compatible Garmin chartplotter and see water depth, engine RPM, wind, speed and custom data fields on your wrist, from the bow, the flybridge or the dock.

Autopilot control. Change heading, engage pattern steering and follow a GPS route from the watch when connected to a compatible Garmin autopilot or GHC 50 controller.

Chartplotter voice control. Use the built-in speaker and microphone to control a compatible chartplotter over Bluetooth.

Fusion-Link audio. Control a Fusion marine stereo from the watch with the built-in Fusion-Link app.

Trolling motor remote. Operate a compatible Garmin Force trolling motor from your wrist.

Tides and anchoring. Built-in barometer, downloadable tide tables, alerts for imminent tide changes, and an anchor drag alarm so you sleep on the hook.

Sailing. Virtual starting line, regatta countdown timer, race start guidance, tack assist mode and a multiday Sail Expedition activity.

Waypoints and charts. Mark chartplotter waypoints from anywhere on the boat. BlueChart g3 coastal and LakeVü g3 inland charts are supported (sold separately), with preloaded TopoActive maps for land.

Boat mode (quatix 8 Pro). Brings your vessel-connected apps to the front of the watch, with autopilot, trolling motor and boat data one tap away.

And Everything a fenix Does Off the Water

The quatix 8 carries Garmin's full flagship feature set: multi-band GPS with SatIQ, preloaded multicontinent TopoActive maps, SkiView for 2,000+ resorts and CourseView for 43,000+ golf courses, training readiness, training status, HRV status, VO2 max, endurance and hill scores, an ECG app, Pulse Ox, sleep coach and nap detection, Body Battery, morning and evening reports, Garmin Pay, offline music from Spotify, Deezer, Amazon Music and YouTube Music on 32 GB of storage, incident detection and assistance, the Garmin Messenger app, an LED flashlight with a red safety mode, and more than 100 activity profiles including wakesports.

It is also a real dive watch: a 40 meter dive rating with single-gas scuba and apnea modes, the Bühlmann ZHL-16c algorithm with gradient factors, nitrox from 21 to 40 percent, a three-axis dive compass and automatic logging to the Garmin Dive app. If you want air integration, multi-gas and SubWave communication, see our Garmin Descent dive computers.

quatix 8 Pro: Satellite and LTE at Sea

The quatix 8 Pro builds inReach technology into the watch itself. With an inReach plan (activated through Garmin, not your cellular carrier) you get two-way satellite messaging up to 50 miles offshore, interactive SOS to Garmin Response 24/7, location check-ins and weather forecasts, plus LTE features in coverage: phone-free voice calls with Garmin Messenger users, two-way messaging and LiveTrack. Garmin includes up to 12 months of free SOS messaging even if the service is later suspended. It is the watch for anyone who fishes, cruises or races beyond cell coverage and wants a safety link that does not depend on a phone or a fixed-mount unit.

Frequently Asked Questions: Garmin quatix

What is the difference between the quatix 8 and the fenix 8?

Same flagship hardware and fitness features. The quatix adds Garmin's marine software: boat data streaming, autopilot control, Fusion-Link, trolling motor control, tide and anchor alerts, sailing race tools and chartplotter waypoint marking. If you own a boat with Garmin electronics, the quatix is the one to buy.

Does the quatix 8 Pro need a subscription?

For satellite and LTE features, yes. Garmin's inReach consumer plans start with a low monthly Enabled tier and step up through Essential, Standard and Premium; the watch works as a full quatix without a plan. Garmin includes up to 12 months of free SOS messaging.

Can I scuba dive with the quatix 8?

Yes, to 40 meters in single-gas scuba or apnea mode, with Bühlmann ZHL-16c decompression, nitrox support and a dive compass. For multi-gas, air integration or technical diving, choose a Descent dive computer.

Which band size does the quatix 8 use?

The 47 mm quatix 8 and the quatix 8 Pro use QuickFit 22 bands; the 51 mm quatix 8 uses QuickFit 26. Both swap without tools.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
