Kitletics Review · 7.6 Solid
Scosche Rhythm24 is a heart-rate monitor. Optical armband with onboard recording — Scosche specialist for watch-free and chest-free training. I'd shortlist it for standalone optical recording when you train watch-free. The trade-off is still optical — more lag than Polar H10 on all-out intervals — Scosche Rhythm+ 2.0 is the cleaner compare when that is most of your week. It fits buyers who actually need a heart-rate monitor, not a one-product rotation.
