• ECG-based heart rate sensing with noise-reduction filtering
• ANT+ plus up to 3 simultaneous Bluetooth connections
• 17 hours of onboard offline recording
• Custom heart rate alert with buzzer
• Rechargeable: up to 100 hours per charge, magnetic charging
• IPX7; sensor weighs 12.4g

Accurate when it counts

The H613 picks up the heart's electrical signal directly rather than estimating it optically, and filters out noise so readings stay steady through sprints, intervals and sweaty indoor sessions. It is a sports device and does not replace medical equipment.

Record without a phone

Onboard memory stores up to 17 hours of heart rate data. Sync afterwards in the OnelapFit app to see duration, calories, average and maximum heart rate and time in zones.

Comfortable, secure strap

The strap uses anti-bacterial, anti-odour treatment and non-slip silicone so it stays in place without overtightening. Replacement straps come in three sizes.

Compatibility & fit

Broadcasts on ANT+ and Bluetooth, so it pairs with most bike computers, sports watches and training apps; Bluetooth supports up to three devices at the same time. Works with the OnelapFit and Magene Utility apps and Magene bike computers (C506 and newer). Alert thresholds are set in OnelapFit. The battery is rechargeable (no coin cell). Replacement straps: S 58-78cm, M 75-100cm, L 93-136cm.
