If you prefer an armband, the Polar Verity Sense is a versatile option with onboard recording and a swimming-goggle clip; Garmin users seeking advanced metrics should consider the newer HRM 600.
Chest straps measure electrical activity and generally respond quickly to changing intensity, while well-fitted armbands can track closely during many steady workouts. The right pick depends on fit, sport, connectivity, and whether you need stored or live readings.

Chest strap or optical armband?
| Consideration | Chest strap | Optical armband |
|---|---|---|
| How it measures | Measures electrical activity through electrodes against the skin | Uses optical sensing to estimate pulse from blood flow |
| Rapid changes in effort | Generally responds quickly, making it a strong interval choice | May lag during rapid changes; performance varies by device and fit |
| Steady running or treadmill workouts | Can provide consistent workout data | Well-fitted models can track closely with chest straps in tested sessions |
| Fit and comfort | Must be snug against the chest; some people find straps restrictive | Must stay snug and block outside light without restricting circulation |
| Swimming | Wireless transmission may not work while submerged; storage or compatible transmission features matter | Water performance varies; the Verity Sense offers a goggle clip and onboard recording |
REI’s comparisons found the COROS Heart Rate Monitor armband, Polar Verity Sense, and Garmin HRM 600 produced nearly identical data in tested running and treadmill sessions. The same REI testing found the COROS Apex 2 Pro wrist monitor diverged substantially from chest-strap and armband traces, and that pool readings were less consistent across device types. These are test findings, not a guarantee of results for every person or workout.
Rank #4
- WORKS WITH EVERYTHING: Polar HRM works with ALL HRM compatible Equipment.
- SUPREME ACCURACY: Widely recognized for its top precision by many sources, Polar H10 is the most accurate heart rate sensor in Polar's history. Polar H10 provides top quality measurement.
- CONNECTIVITY: Bluetooth, ANT plus and 5 kHz provide an excellent variety of connection options. You can use Bluetooth and ANT plus connections simultaneously as well as two Bluetooth connections simultaneously.
- POLAR PRO CHEST STRAP: With improved electrodes, an easy-to-use buckle and silicone dots, the strap is comfortable and interference-free.
- VERSATILITY: Polar H10 is fully waterproof and it has internal memory for multiple hours.
How to get better readings
- Moisten chest-strap electrodes. Polar’s setup guidance recommends a good skin connection. Moisten the contact areas and wear the strap snugly, with the transmitter centered.
- Keep the receiving device in front of you. Polar advises this because a phone in a back pocket or backpack can reduce Bluetooth reliability.
- Pair and update as directed. Polar advises pairing the H10 with Polar Flow first so firmware can be updated. For other products, use the manufacturer’s or fitness app’s pairing steps.
- Position an armband securely. Keep it snug enough to block outside light without restricting circulation. For swimming with the Verity Sense, make sure the goggle clip holds the sensor firmly against the temple.
- Check connection compatibility. Confirm whether your receiving device needs Bluetooth, ANT+, or both. The COROS armband is Bluetooth-only and will not work with ANT+-only equipment.
- Give the Wahoo TRACKR its first charge. It ships in low-power mode and needs to be connected to a charger and power source before first use.
What testing supports
REI’s comparisons found that dedicated chest straps and armbands tracked closely in several steady-state and interval comparisons, while its tested COROS Apex 2 Pro wrist monitor diverged substantially. REI also observed reduced consistency underwater. These results support choosing a dedicated monitor for training when readings matter, but they do not mean every armband is inaccurate or that every strap will fit every person equally well.

Optical sensors can face challenges during gripping, arm flexion, and abrupt movement. For rapid changes in effort, a chest strap remains the safer general recommendation; during steady workouts, a well-fitted armband may be a comfortable alternative.
Heart-rate monitors are fitness tools, not substitutes for medical diagnosis. Seek medical help for concerning symptoms rather than relying on a training sensor.
FAQ
Are chest straps more accurate than armbands?
Chest straps generally have an advantage when effort changes quickly because they measure electrical activity. Research comparisons found several armbands tracked closely with chest straps in running and treadmill sessions, so a well-fitted armband can be a good choice for many steady workouts.
Does the COROS Heart Rate Monitor work with ANT+?
No. It uses Bluetooth and does not support ANT+. Check that your watch, bike computer, or other receiver supports Bluetooth before buying.
Recommended Free Tools
Can I use a heart-rate monitor while swimming?
Some models support swimming, but readings and transmission vary underwater. The Polar Verity Sense can record workouts internally and includes a swimming-goggle clip. Garmin HRM 600 supports swimming heart-rate transmission only with compatible Garmin devices.
How do I get a reliable reading from a chest strap?
Moisten the electrode areas, wear the strap snugly against the skin, and keep the transmitter centered. If using Bluetooth, keep the receiving device in front of your body rather than in a back pocket or backpack.
What should I check before buying a monitor?
Match its connection standards to your receiving device, check strap or band sizing, and decide whether you need onboard storage, rechargeable power, or specific sport features. Battery figures also describe different things: coin-cell hours, active operating time, and calendar estimates are not directly interchangeable.
The Bottom Line
The Polar H10 is the best general-purpose pick for athletes who want a dependable electrical chest strap and internal recording. Choose the Garmin HRM 600 for compatible Garmin features, Wahoo TRACKR HEART RATE for a rechargeable chest strap, or Polar Verity Sense for an armband with onboard storage and a swimming-goggle clip. Before buying, check fit, receiver compatibility, and whether your sport needs live readings or stored data.
