COROS PACE 3: PPG Sensor
The photograph is a COROS PACE 3 with a nylon band. COROS lists optical heart rate and SpO2, 15 days of regular use, 38 hours of GPS and 5 ATM water resistance for the PACE 3. The VERTIX 2S is a different watch.
COROS lists optical heart rate and SpO2 sensors on the PACE 3, 15 days of regular use, 38 hours of GPS and 5 ATM water resistance (COROS: PACE 3).
The COROS comparison also names the VERTIX 2S. That is a different watch. COROS lists 36 days of regular use, 118 hours of full GPS and 10 ATM for the VERTIX 2S (COROS: VERTIX 2S). The photograph on this page is the PACE 3, not the VERTIX 2S.
ChatPPG’s accuracy database has no COROS rows, and this guide does not add any.
