Polar M400 Hr
Question about Polar M400 Hr
Accessories for Polar M400HR. Does the Polar Heart Rate Sensor H1 band fit this watch or does H7 have to be purchased as well?
Helpful answer
Polar H1 is NOT compatible because it works with a completely different radio technology (Gymlink). However, the M400 only understands Bluetooth Smart (BLE). Instead of the H7 (BLE + Gymlink), I would personally go for a Wahoo TICKR model, as it works with BLE and ANT+ (Garmin). The battery also lasts longer with the TICKR than with the H7.
Hello, the M400 HR already comes with the heart rate chest strap (unlike the M400). This strap is elastic and perfect. I am very satisfied with the product, very good price/performance ratio.
