Amazfit T-Rex 3 Pro vs Garmin Fenix 9

The Fenix 9 costs $600 more and adds ECG, max analytics, streaming music sync, and Garmin's ecosystem. The T-Rex 3 Pro matches it on offline maps, dual-band GPS, and 10 ATM diving support, beats it on GPS battery on paper (38 hours versus 30), and weighs 23 grams less. The Fenix 9 only launched in late August, so it has no track record yet.

The Full Story

The T-Rex 3 Pro adds a Grade 5 titanium bezel and buttons, sapphire glass, a 3,000-nit AMOLED display, a dual-color LED flashlight, and a speaker for Bluetooth calls to Amazfit's rugged line, and it's the first T-Rex in a smaller 44mm size. You still get dual-band GPS, offline maps, 10 ATM water resistance with diving to 45 meters, and up to 25 days of battery on the 48mm model. It costs over $100 more than the regular T-Rex 3, and like the rest of Amazfit's lineup it has no ECG.

The Fenix 9 pushes display brightness to 3,000 nits while slimming down the overall profile with a full titanium bezel and rear cover. Adding 64GB of storage, 3D topo mapping, and dedicated rucking and endurance stamina metrics, it sits right at the top of Garmin's multi-sport lineup.

*Estimated — this model's exact GPS battery life isn't published by the manufacturer. All figures are standard GPS mode, midsize case, no solar boost.

†Estimated — this model launched too recently to have an established customer rating yet.
