Garmin HRM-Pro Plus Heart Rate Monitor was $149.99, now $109.90 on Amazon | Save 27%

Rated best among premium heart rate chest straps by our reviewers, Garmin's HRM-Pro adds extra features like counting steps and analysing your gait as you run.

Either way, we found data recording reliable and seemingly accurate.
