Garmin HRM Tri

This is a really small and light (around 49g) heart rate monitor chest strap is the most rounded tracker for the triathletes with a water proof rating to 5 meters. It has plenty of smart functions to help improve your running, cycling and swimming (both outdoor and indoor) performance.

Garmin HRM Tri has an inbuilt accelerometer that will keep tabs of foot strike rate, vertical oscillation and ground contact time.
Another great feature is the specific heart rate training zones (energy efficient zone, aerobic zone and anaerobiz zone) which you can set for training at your optimal fitnes level and performance.

However, you may find issues with the pool as it does not have enough ‘grip’ to your body, especially when you push off the wall.

The design has no visible seams and the edges are comfortably curved to reduce chaffing to the skin or any wet-suit issues.

In terms of tracking, it can track your pace, heart rate, distance traveled, duration of a session, SWOLF (swimming score), calories burned and plenty more of in-depth table and graphs that will give you a split of your performance from average pace, best pace, average heart rate, maximum heart rate and so on.

With the Garmin HRM TRI you must have a compatible Garmin watch (FR920XT/Epix/Fenix3 and the newer versions after) to pair with, and the chest strap will NOT show your heart rate live during swim sets, as ANT+ signals cannot transmit through water. The interval/set based HR results can only been shown after a set. However it is a quality fitness heart rate monitor.
