Polar H10 vs Garmin HRM 600: Choose by Compatibility and Recording Workflow

Both straps document ANT+, and each documents Bluetooth support with different compatibility limits; the H10 also adds 5 kHz Polar GymLink. The H10 starts its stored one-session recording in Polar Beat, while the HRM 600 starts timed activity recording in Garmin Connect and needs a compatible Garmin watch for certain running features. No universal compatibility or accuracy winner is established.

The buying question

Should you choose the Polar H10 or Garmin HRM 600 for your receiver compatibility, training data and watch-free session workflow?

Both straps document ANT+; Bluetooth is also documented for both, with Garmin specifying some Bluetooth connections in open mode for compatible devices. The H10 additionally documents 5 kHz Polar GymLink and starts its one-session memory through Polar Beat; the HRM 600 records timed activities through Garmin Connect and offers watch-dependent Garmin metrics.

Quick verdict

When to skip: Skip the HRM 600 if you need its pace-and-distance feature but do not have the compatible paired Garmin watch required for that feature. For watch-free session recording, skip whichever workflow does not fit your setup: the H10 session starts in Polar Beat; HRM 600 activity recording starts in Garmin Connect.
When the recommendation changes
  • Both products document ANT+ and Bluetooth support with different device/profile limits; the H10 additionally documents 5 kHz Polar GymLink. The receiver's exact connection and required data, plus the exact Garmin watch for Garmin-only metrics, can change the choice.
  • If you do not want to start sessions in Polar Beat or Garmin Connect, neither stored-session workflow may suit you.

The differences that matter

Connection Compatibility And Training Data

Polar H10 Heart Rate Sensor (Black, M-XXL)

Polar says the H10 transmits heart-rate data over Bluetooth, ANT+ and 5 kHz Polar GymLink; the receiving device or app must support the relevant connection/service.[2]

Garmin HRM 600 Heart Rate Monitor (Black, M-XL)

Garmin documents secure and open HRM 600 connections. In open mode, ANT+ and some Bluetooth connections can be used with compatible third-party watches, tablets and fitness equipment. Garmin's pace-and-distance feature requires a compatible paired watch in range, and not every compatible Garmin watch supports every advanced HRM 600 feature.[7, 9, 10]

What this changes: Both document ANT+, while Bluetooth support has device/profile limits and is not an H10-only advantage. The H10's 5 kHz Polar GymLink is a distinct documented option. Match the exact receiver and data needed; check the exact Garmin watch before choosing an HRM 600-only running metric.[2, 7, 9, 10]

The better fit depends on your priorities

Watch Free Session Recording Workflow

Polar H10 Heart Rate Sensor (Black, M-XXL)

The H10 stores one heart-rate session. Start it in Polar Beat; the app transfers the session from the sensor after training.[3, 4]

Garmin HRM 600 Heart Rate Monitor (Black, M-XL)

The HRM 600 records a timed activity with Garmin Connect for up to 24 hours. Garmin states it will not start a recording below 5% battery and automatically stops recording if charge drops below 5% during the activity. Start from the HRM 600 device page; the phone can be out of range during recording, then save in the app. Removing the strap without a manual stop/save causes it to stop, save and attempt a sync.[8]

What this changes: Both have a documented watch-free path, but the app used to start and retrieve the session differs. Pick the workflow that fits your sport and the training app you want to use.[3, 4, 8]

The better fit depends on your priorities

Battery Maintenance

Polar H10 Heart Rate Sensor (Black, M-XXL)

The H10 uses a replaceable CR2025 coin cell; Polar advertises up to 400 hours of battery life.[5, 1]

Garmin HRM 600 Heart Rate Monitor (Black, M-XL)

The HRM 600 has a rechargeable battery; Garmin advertises up to two months per charge.[10]

What this changes: The choice is between replacing a coin cell and recharging the module. The published hours and months are not a normalized runtime test, so they do not establish which lasts longer in a buyer's use.[5, 1, 10]

The better fit depends on your priorities

Best for your routine

A buyer whose equipment specifically needs 5 kHz Polar GymLink, or who prefers the H10's Polar Beat-started one-session memory workflow

Best fit: Polar H10 Heart Rate Sensor (Black, M-XXL)

Based on listed features, not comparative testing.

These are the H10-specific GymLink and session-start options documented for this comparison; Bluetooth and ANT+ should be matched to the exact receiver rather than treated as an H10-only advantage.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare current checkout offers against the connection and recording features you will use; no offer comparison was assessed for this article.

Current offers and price history were not assessed; no purchase-timing recommendation is supported.

Limitations

  • Compatibility depends on the specific watch, phone, app or fitness equipment. Check that setup's supported connection and data before buying.
  • Garmin says some HRM 600 features require a compatible watch, and not all compatible watches support every advanced running or swimming feature.
  • The two manufacturers' battery-life statements use unlike published units and conditions; this comparison does not rank runtime.
  • No controlled head-to-head accuracy, comfort, reliability or training-outcome evidence was reviewed, so no performance winner is claimed.
  • Current offers and price history were not assessed.

Questions shoppers ask

Can the HRM 600 give every Garmin watch the same running data?

No. Garmin says some running data requires a compatible watch, and it cautions that not all compatible watches support every advanced HRM 600 feature. Check your exact watch model and the metric you want.

Can either strap record a workout when I am not wearing a watch?

Both have documented watch-free session workflows, but the start and retrieval apps differ. Start the H10's one-session recording in Polar Beat; start an HRM 600 timed activity in Garmin Connect. Garmin states that the HRM 600 will not start recording below 5% charge and stops if charge falls below 5% while recording. Their documented workflows and saved-session handling differ.

Methodology and sources

Compared each exact model's published connection options, watch-free recording steps, session limits and battery maintenance. Recommendations are conditional on the buyer's exact receiver and app. Manufacturer runtime claims are not treated as a controlled comparison.
