Follow ZDNET: Add us as a preferred source sports a two-color LED flashlight that competes with Garmin.
In addition to the LED flashlight, the new T-Rex 3 Pro is available in two sizes, so everyone can enjoy the watch no matter their wrist size. It has an integrated speaker and microphone for hands-free calling and Zepp Flow control, and supports free downloadable navigation maps, including snow ski resort maps.
The T-Rex 3 Pro is designed for outdoor adventurers, including trail runners and endurance athletes. Its rugged titanium build, sapphire crystal display, long battery life, and durability include operating in temperatures as low as -30 degrees Celsius.
The addition of a 44mm model for smaller wrists is a nice addition to the series, and while smaller than the 48mm model, it still supports up to 19 days with typical usage or 29 hours in precision GPS mode (highest battery consumption mode).
Last year, after a 30-year hiatus, I started downhill skiing again. I now have all of my gear and an Icon pass to tackle the slopes this winter. The T-Rex 3 Pro supports resort ski maps with slope color codes and lift dynamics, so I can’t wait for the snow to come so that I can test out the watch in that environment.
The T-Rex 3 Pro provides over 180 sport modes for you to select and customize. It was great to see a dog walking one since that is something my wife and I do regularly. With other watches, I have just been selecting walking, but if you walk dogs, you know there are bathroom breaks, sudden bursts of energy, and more, so it’s nice to see Amazfit provide a more specific common activity.

I am currently testing a Coros Nomad that has extensive fly fishing support, so I looked at the T-Rex 3 Pro and found the fishing mode provided by Amazfit supports cast tracking and fish logging, in addition to navigation, heart rate tracking, and more. I highly recommend that you explore your preferred activity settings and customize each for your personal needs.
The T-Rex 3 Pro is a rugged watch with some bulk to support the large capacity battery, so it is not the most comfortable watch to sleep with. Thankfully, the Amazfit Helio Strap is a fantastic, affordable wearable that fits seamlessly on your wrist or arm to track all of your sleep metrics and then syncs to the Zepp ecosystem.
The Helio Ring can also be used for unobtrusive health and wellness tracking when you are not wearing the Amazfit T-Rex 3 Pro.
