For Mr. Mo*) GARMIN HRM4-Run Heart Rate Monitor (with original box)

This is the Garmin Heart Rate Monitor HRM4-Run.
I am selling it because it has been used infrequently.
Please check the photos for the condition.

I have replaced the battery with a new CR2032 button cell and confirmed the connection (photos 4 and 5).
The battery is included, so you should be able to use it immediately after pairing.

The original box, instruction manual, and extended strap are also included.

Thank you for looking.

[Product Description]
This is a heart rate monitor with a built-in G-sensor.
In addition to heart rate, compatible devices with Running Dynamics can measure the following running metrics:
■ Vertical Oscillation: Measures the vertical motion of your torso during training in cm.
■ Ground Contact Time: Measures the time your feet are in contact with the ground.
■ Cadence: Measures your steps per minute.

*Devices that cannot use the Running Dynamics function will only display heart rate.

*The transmitter and strap are integrated, resulting in a more compact design. (The transmitter cannot be removed.)
*This is the successor to the HRM-Run heart rate monitor, with the same functionality.
