The Full Picture
The HRM-Dual solved the old problem of choosing Bluetooth OR ANT+: it broadcasts both, so your watch and your bike computer see it simultaneously. The strap is softer than the old HRM-Run and the CR2032 lasts years. It is the quiet workhorse serious trainers keep buying.
Bottom Line
The dual-protocol chest strap with a 3.5-year battery — Garmin HRM-Dual.
