For accuracy, chest straps still win (especially when you catch a real drop)
Wrist sensors are convenient, but if you care about accuracy during workouts, dedicated heart rate monitors still have a real edge.
Track the model you want and let alerts catch the drop — these swing more than most people expect.
Best time to buy heart rate monitors
Accuracy gear often goes on deal without fanfare. Alerts do the work.
Best time to buy
- Rotating discount periods (these drop quietly, not loudly)
- Post-holiday / post-resolution demand dips
- When you see a real drop—often short-lived
Avoid if you can
- Impulse buys during New Year hype without price context
- Buying a no-name strap just because it’s “on sale”
Quick buyer’s guide
What to look for
- Chest strap vs armband (chest is usually most accurate)
- Bluetooth vs ANT+ depending on your devices
- Battery style (replaceable vs rechargeable)
- Comfort + stability (slipping ruins readings)
Common mistakes
- Buying a random no-name strap and hating the comfort/accuracy
- Not checking Bluetooth/ANT+ compatibility up front
- Paying full price when these rotate discounts often
Best for
- Runners and cyclists
- HIIT training accuracy
- People optimizing training zones
