Amazfit T-Rex 3 Pro In-Depth Review: Premium Features at a Mid-Range Price?

Upgraded Materials and Display

• 💎 The T-Rex 3 Pro features a titanium bezel and buttons, a significant upgrade from the standard version's stainless steel.
• 🛡️ It also boasts a sapphire lens for enhanced scratch resistance, replacing the Gorilla Glass found on the original T-Rex 3.
• 💡 The display remains a 1.5-inch size but is brighter, with a peak brightness of 3,000 nits compared to the original's 2,000 nits.
• 📏 A new 44mm size option is introduced alongside the standard 48mm case, offering a more comfortable fit for smaller wrists.

Enhanced Functionality and Battery Life

• 🎙️ The Pro model includes a microphone and speaker, enabling workout summary readouts and turn-by-turn navigation alerts.
• 📞 It also supports taking calls directly from the watch when paired with a smartphone.
• 🔦 A notable addition is a built-in LED flashlight with multiple brightness levels and a red light mode for nighttime use.
• 🔋 Battery life is rated between 10 to 25 days, with the reviewer consistently getting about a week and a half even with heavy usage and always-on display.

GPS and Navigation Features

• 🗺️ The T-Rex 3 Pro utilizes a dual-band satellite chipset for improved GPS accuracy, featuring a smart mode that automatically adjusts accuracy based on environmental conditions.
• 📍 New navigation features include offline maps with points of interest (landmarks, trailheads) and the ability to search for and navigate to these locations.
• 🔄 A roundtrip route creator for walking, running, and cycling is introduced, allowing users to set distance and direction.
• ⚠️ Navigation accuracy, particularly for cycling at higher speeds, experienced delays and issues with rerouting, though running performance was generally good.

Performance and Accuracy

• 🏃 GPS accuracy was generally good for trail running, even in challenging conditions like tree cover and under rock faces.
• 🚴 For cycling, the smart GPS mode showed corner cutting and issues reacquiring signal after tunnels, suggesting the highest accuracy mode is preferable for this activity.
• ⛰️ Elevation gain reporting was inconsistent, sometimes accurate, but often slightly low or, in one instance, significantly high.
• ❤️ Heart rate accuracy was decent for indoor cycling and running but showed more variability during outdoor cycling and trail running due to bumps, grip, and cadence lock, especially on steep inclines/declines.
• 💪 Weight training heart rate tracking was surprisingly not bad, despite the challenges of wrist-based optical sensors during such activities.

Overall Value and Quirks

• 💰 The T-Rex 3 Pro is considered a fantastic deal for its features, especially given its price point compared to competitors.
• 🤔 However, the new navigation features, while impressive for the price, are still being refined and have some quirks that suggest they might have been better rolled out later.
• 👍 The brand's history of updating existing devices provides hope for future improvements to the T-Rex 3 Pro's software.
• 🔗 For those seeking maximum accuracy, pairing the watch with an external heart rate strap is recommended.
