Expert opinion
The quatix 8 Pro is the Fenix 8 Pro 47mm rebuilt for people who spend their time on boats. With no phone aboard, it can call for help, text home and run parts of the boat from the wrist, up to 80 km offshore.
Boat mode puts autopilot control, the trolling motor remote, Fusion audio and streamed chartplotter data such as depth, engine RPM and wind on the watch while you are on the water, then hides them ashore. Chartplotter voice control keeps your hands on the wheel. LTE covers calls, messages, LiveTrack and weather, and satellite messaging and SOS take over beyond mobile coverage; both need an inReach subscription. The 47mm case lasts up to 15 days as a smartwatch, about half the 29 days of the 51mm quatix 8.

How long does the quatix 8 Pro battery last?
Garmin rates it for up to 15 days as a smartwatch, 44 hours with GPS only and 30 hours with all systems and multi-band. LTE LiveTrack cuts that to 12 hours.
What is the difference between the quatix 8 Pro and the quatix 8?
The Pro adds LTE and satellite calls, messaging and SOS, a titanium rear cover and preloaded maps on every model. It comes in 47mm only, is 2.2mm thicker than the 47mm quatix 8, and lasts 15 days as a smartwatch against 16 days.
