Garmin's HRM-Tri strap is designed for adding heart-rate measurements to open-water swims or occasional pool swims. It allows HR data to be stored while in the water when no connection to the device is available and then uploads the data to the device using ANT+® connectivity at the end of the session. The inclusion of accelerometers lets it calculate advanced Running Dynamics as well, when used with compatible devices.
