Description

HR transmitter and chest strap. German manufacturer. Used but working well. Works by ANT+ to connect to smart phone, fitness watch, bike computer, or other devices to detect heart rate. None of the HR monitors on the market that are worn on the wrist are accurate; a chest strap is required for correct measurement of heart rate.
