Polar H9
Score: 83/100
Garmin Forerunner 165
Score: 82/100Rankings
The Polar H9 is a chest-mounted ECG heart-rate sensor offering exceptional accuracy and a 400-hour battery life. Its main trade-off is the lack of onboard storage and reliance on a replace-once coin cell battery. Ideal for athletes who need precise data across multiple sports and appreciate dual-protocol connectivity.
Garmin Forerunner 165 is an entry-level GPS running smartwatch featuring a vibrant AMOLED screen, up to 11 days of battery life, and comprehensive health metrics like Pulse Ox and recovery insights. It lacks advanced multi-sport modes and built-in music storage, which may limit power users. Best suited for beginners to intermediate runners who value a bright display and long endurance.
