This is the Garmin HRM-Pro Plus chest strap heart rate monitor. I purchased it around November 2022 and used it about 5 times a week. I'm selling it to someone who can make good use of it, as I'm organizing my equipment. 【Condition】 • Operation: Confirmed. Connection with Garmin watches and cycle computers is also good. • Appearance: The strap shows signs of use, but the sensor itself has no noticeable scratches. • Hygiene: I washed it by hand after each use and stored it carefully in a shaded area. I have cleaned it again before listing it, but as it is a sensor that comes into direct contact with the skin, please refrain from purchasing if you are concerned about hygiene. 【Main Features】 • Tool-free battery replacement: Unlike the previous model (Pro), this latest model allows for easy battery replacement by simply twisting the cap. • Running dynamics measurement: Detailed analysis of vertical oscillation, ground contact time, stride length, etc. is possible. • Communication standards: ANT+ and Bluetooth compatible. • Standalone function: Even without a watch, it records steps, calories, and intensity (minutes) and can be synced later. 【Included Items】 • Main unit • Outer box • Instruction manual ※ Everything in the photos is included. 【Shipping】 • Shipping method: Will be shipped via Rakuraku Mercari (Takkyubin Compact). • Packaging method: The outer box will be folded for packaging. Please purchase with the understanding that this is a used item. Instant purchase is OK! I am also selling a Forerunner 255. If you purchase both items, please let me know in the comments. I will offer a significant discount on this sensor!
