The Quantified Scientist - Garmin Instinct 3 In-Depth Scientific Review
The Garmin Instinct 3 is designed as an adventure watch with a rugged build and several upgrades from its predecessor. It offers two display options: the AMOLED version with a vivid, colorful screen, and the traditional MIP solar model that extends battery life. The AMOLED version provides a more pleasant viewing experience but sacrifices battery longevity compared to the solar model. The Instinct 3 includes features like dual-frequency GNSS, advanced fitness metrics, and a built-in flashlight. However, it still uses Garmin's older Generation 4 Optical heart rate sensor, lacking ECG and skin temperature capabilities, and does not have a touchscreen interface.
In terms of performance, the Instinct 3's GPS tracking is generally reliable, showing consistent results in tests, though not perfect. Heart rate tracking is adequate for most users but struggles with rapid changes, particularly during activities like indoor cycling and running. The watch performs moderately well in sleep tracking, with decent accuracy in detecting deep and light sleep but poor REM sleep detection. Overall, the Instinct 3 is a solid choice for those who prioritize rugged design and battery life over the latest sensor technology and touchscreen convenience.
Key Points:
- The Instinct 3 offers AMOLED and MIP solar display options, with the AMOLED providing better visuals but shorter battery life.
- It includes dual-frequency GNSS and advanced fitness metrics but lacks a touchscreen and uses an older heart rate sensor.
- GPS tracking is reliable, though not flawless, and heart rate tracking struggles with rapid changes.
- Sleep tracking is decent for deep and light sleep but poor for REM sleep detection.
- The watch is suitable for users valuing rugged design and battery life over cutting-edge features.

5. ⏳ Battery Performance Expectations
- The larger solar model in Smartwatch mode lasts up to 40 days, while the smaller version lasts 28 days.
- AMOLED versions have reduced battery life, with the larger version lasting 24 days and the smaller version 18 days in Smartwatch mode.
- For continuous workout with optimal satellite settings, the smallest AMOLED version lasts up to 23 hours.
- Continuous workout time extends from 34 to 60 hours with larger solar models.
6. 📡 GPS Tracking Evaluation
- The Garmin Instinct 3 quickly acquires GPS signals, often instantly, which is a significant improvement over many other devices that may take several minutes.
- During a test cycling the same route nine times, the signals were mostly consistent, with only minor deviations indicating high accuracy in tracking.
- Instances of deviations were often due to real-world factors such as construction or detours, rather than device inaccuracies.
- While cycling back from work, some deviations were noted; however, these were not major and overall performance was deemed better than most devices.
- The GPS tracking performance, despite not being perfect, is on par with the best in the market, providing reliable tracking with few errors.

8. 🏃 Running and Outdoor Cycling Performance
- The Instinct 3 shows a correlation of 0.89 with reference devices, indicating decent but improvable heart rate tracking accuracy during extreme intervals, with deviations up to 20 BPM.
- In individual running sessions, consistent performance was noted, but the device struggled with rapid heart rate changes during interval training, suggesting it may not meet the demands of users requiring high precision.
- Compared to other Garmin devices like the Duro 3, Vivoactive 5, and Phoenix 8, the Instinct 3 performs similarly, positioned in the mid-range for heart rate tracking capabilities.
- The Amazfit T-Rex 3 has improved significantly in heart rate tracking accuracy, setting a new benchmark that Garmin's Instinct 3 has yet to meet.
- For general users, the Instinct 3's performance may be adequate, but it may fall short for those needing highly accurate data, especially in varied outdoor conditions.
- Deviations in heart rate tracking during extreme intervals highlight the need for further enhancements to ensure precision across different exercise intensities.
