How to choose
- Accuracy & Sensor Type. Chest straps with electrical sensors (ECG) are more accurate than optical armbands, especially during high-intensity intervals. For most users, optical is fine for steady-state workouts, but chest straps are preferred for serious training.
- Comfort & Fit. Look for adjustable straps with soft fabric. Armbands should be snug but not tight. Owner reviews often mention if a strap causes chafing or slipping, so read feedback on long-term wear.
- Battery Life & Type. Chest straps typically use replaceable coin cell batteries lasting hundreds of hours, while armbands have rechargeable batteries lasting 8-24 hours. Consider your usage frequency when choosing.
- Connectivity & Compatibility. Bluetooth and ANT+ are standard. Ensure the monitor works with your devices (phone, watch, bike computer, gym equipment). Some models offer dual Bluetooth for connecting to two devices simultaneously.
- Water Resistance. If you swim or sweat heavily, look for at least IPX7 or 5 ATM water resistance. Not all budget monitors are swim-proof, so check specs if water activities are planned.
