Overview

The Garmin 010-12883-00 is a chest-strap heart rate monitor that sends real-time heart rate over ANT+ and Bluetooth Low Energy to compatible devices and fitness equipment. It uses a user-replaceable CR2032 (3 V) battery and is rated for up to 3.5 years of use based on 1 hour per day.

For on-water training and everyday boating life, it handles sweat and spray with a 1 ATM water rating and operates from -5°C to 50°C. It does not transmit heart rate data while swimming, so it is best used for workouts, deck work, and topside activity rather than in-water sessions.

Key features

• Transmits heart rate data over ANT+ and Bluetooth Low Energy for use with compatible watches, phones, tablets, and fitness equipment
• 1 ATM water rating for sweat, rain, and incidental spray; does not transmit heart rate data while swimming
• User-replaceable CR2032 (3 V) battery with up to 3.5 years of life based on 1 hour/day
• Operating temperature range from -5°C to 50°C for training in cool mornings through hot cockpit conditions
• Pairs with devices within 3 m; some Garmin devices support very close-range pairing
• Snap-on module with a strap you can clean after use by removing the module first

Installation and setup

Wear the strap directly on your skin just below your sternum, snug enough that it stays put when you are moving around the boat. Wet the electrodes and contact patches on the inside of the strap before use, then snap the module onto the strap and keep the logos facing upright.

For pairing, bring your compatible device within 3 m of the strap and follow the device pairing menu for ANT+ sensors or Bluetooth accessories. Keeping some distance from other nearby wireless sensors during setup can help avoid pairing to the wrong device.

Compatibility and fit

This strap pairs with ANT+ compatible devices and can also connect over Bluetooth to a smartphone, tablet, smartwatch, or compatible fitness equipment. It is a personal sensor, so there is no boat wiring, network gateway, or 12V/24V connection involved.

Fit comes down to strap tension and placement. If the strap is too loose, heart rate readings can drop out when you are working the helm, grinding a winch, or doing interval training on deck. A snug fit and pre-wetted electrodes typically stabilize readings.

Maintenance and care

Salt and sweat buildup on the strap can reduce reading quality over time, so rinsing after each use is worth doing, especially after a salty day on the water. Remove the module before washing the strap, and avoid using a dryer; hanging it up or laying it flat helps the strap last.

Battery replacement is done from the back of the module using the supplied Torx T5 screwdriver. Remove the four screws, swap in a new CR2032 with the positive side facing up, keep the O-ring gasket in place, and reinstall the cover without overtightening.
