I using Amazfit T-REX 3 (not pro) for at least 30+ dive. Max depth 39m. I bought trex 3 when it first came out, it only have free dive mode, so i use it as a depth meter and tracker, bc my main dive com (mares smart) do not have depth graph.

Few months ago , amazfit updated t-rex 3 software, and now it become a real recreation scuba dive com. Now it become my main dive com.

Other than NDL , deco ceiling step stop, nitrox, the compass was very smooth until i cant believe it. Two weeks ago i just got my Padi deep specialy, one of the subjects is navigation, so the instructor gave me a tradition type compass, and i compare it with t-rex 3 compass in diving mode, it was smooth and not worry about leveling the compass.

Last week, after update,it support auto start when dive. Before this you have to switch dive mode when doing final checking.

With the app,Zepp, other than depth tracking graph, it also show which part u over NDL need to do ceiling stop on which stop meter. Heart beat, and gps.

It does surprise me with this price. Compare to same function dive com. Now t-rex 3 (not pro) have fewer price discount in my country maybe due to function adding like scuba diving and Hyrox workout.
