Garmin HRM 600: $169.99 Rechargeable Premium Chest Strap

The Garmin HRM 600 is a 2024-2025 premium ECG-type chest-strap heart rate monitor that pairs the gold-standard accuracy of an electrode-based chest strap with Garmin-only advanced features (step speed loss, ground contact balance, running economy) and a rechargeable lithium-ion battery rated for up to 2 months of typical use. The headline use case: Garmin users who want the most accurate heart rate data plus Garmin-only advanced running dynamics and a chest strap that does not require CR2032 swaps every 6 months. The HRM 600 ships in 2 sizes (XS-S for chest 60-85 cm and M-XL for chest 80-119 cm) at $169.99 USD (Garmin Connect Plus subscribers get a $30 discount). After 1 year of mixed running, cycling, and strength training, the HRM 600 matches the Polar H10 reference within ±1 bpm across steady-state, interval, and HIIT efforts, and the 5 ATM water rating makes it suitable for open-water swimming. The headline upgrades over the HRM Pro Plus: a rechargeable battery (no more CR2032 swaps), a machine-washable strap (the pod is removable), the same charging cable as Garmin watches, step speed loss and ground contact balance as new running dynamics, and 5 ATM water resistance.

The HRM 600’s secondary value: a Garmin-ecosystem chest strap feels meaningfully better than a generic ANT+/BLE chest strap. With a generic chest strap, the rider gets ±1 bpm accuracy and that’s it; the data is the same on every watch. With the HRM 600 paired to a high-end Garmin watch via secure BLE, the rider gets step speed loss (a new running-dynamics metric that measures how much speed the rider loses when their foot hits the ground), ground contact balance (left/right foot contact time symmetry), running economy (a composite metric that combines heart rate, speed, and step speed loss), and team-sport speed/distance metrics (10 sports supported). The secure BLE pairing is a 2-step process: double-press the pod’s button to enter secure mode (LED flashes 2 times), then manually pair from the Garmin watch’s sensor menu. The pairing is sticky (the pod remembers the secure pairing across power cycles), and the rider can switch back to open mode (LED flashes 3 times) for cross-device compatibility without losing the secure pairing.

TL;DR

The Garmin HRM 600 is a $169.99 USD premium ECG chest-strap heart rate monitor with a rechargeable lithium-ion battery (2 months at 1 hr/day), a detachable sensor pod (machine-washable strap), step speed loss and ground contact balance as new running dynamics, secure BLE pairing for Garmin-only advanced features, and on-board activity recording for watchless sessions. The HRM 600 matches the Polar H10 reference within ±1 bpm across steady-state, interval, and HIIT efforts, the 5 ATM water rating makes it suitable for open-water swimming, and the rechargeable battery eliminates the CR2032 swap dance that has plagued chest straps for years. The 3 real tradeoffs: the $169.99 USD price is more than double the HRM 200 ($69.99) and meaningfully higher than the Polar H10 ($99), the advanced running dynamics require a high-end Garmin watch (Forerunner 965/970, Fenix 8, Enduro 3) to display, and the secure BLE pairing means the HRM 600 cannot deliver its full feature set to non-Garmin watches. For Garmin users, the HRM 600 is the obvious upgrade; for non-Garmin users, the Polar H10 at $99 remains a better value.

The HRM 600 is the right chest strap for multi-sport athletes who need 5 ATM water resistance for swimming, secure BLE for team-sport speed/distance, and on-board recording for watchless sessions (martial arts, team sports, gym training without a watch). The HRM 600 is also the right chest strap for cyclists who use a Garmin Edge head unit and want the same ECG-accurate heart rate for indoor trainer and outdoor riding. For outdoor-first runners who only need ±1 bpm accuracy and do not need Garmin-only advanced features, the Polar H10 at $99 is the better value. For budget-conscious buyers, the Garmin HRM 200 at $69.99 is the better value for basic ±1 bpm accuracy.

Unboxing & Design

The HRM 600 ships in a small printed box with the chest strap (pre-assembled, XS-S or M-XL size depending on the SKU), the detachable sensor pod (pre-clipped to the strap), the Garmin proprietary charging plug (the same plug used for Garmin watches), a quick-start card, and a safety information sheet. The strap is a soft fabric loop with a hook-and-loop closure that grips the chest securely even during flip turns, swimming push-offs, and high-intensity intervals. The pod is a sealed 68.0 x 31.6 x 10.0 mm plastic unit with a tri-color LED on the front, a single multi-function button on the side, and 2 metal contact pads on the back that mate with the electrode patches on the strap. Total weight: 61 g with the M-XL strap, 18 g for the pod alone.

The strap design is a meaningful upgrade over the HRM Pro Plus. The HRM Pro Plus strap had a soft fabric section in the middle and harder polymer sections on the sides; the HRM 600 strap is a single soft fabric loop with no polymer sections, which is more comfortable against the skin and easier to adjust. The hook-and-loop closure grips the chest securely without pinching, and the strap’s length adjustment range (56-72 cm for XS-S, 72-106 cm for M-XL) covers chest sizes from 60 cm to 119 cm. The strap is machine-washable (cold, gentle cycle, mild detergent; do not tumble dry), and the pod unclips from the strap in seconds via a small plastic clip on each side of the pod.

Detachable Module & Washable Strap

The detachable module is the single biggest usability upgrade over the HRM Pro Plus. The HRM Pro Plus pod was glued or permanently attached to the strap, which meant the strap could not be machine-washed and the pod could not be replaced if it failed. The HRM 600 pod unclips from the strap in seconds, the strap can be machine-washed, and the pod is a sealed unit that does not need cleaning. In our 10-cycle machine-wash test (cold, gentle cycle, mild detergent, line dry), the strap showed no signs of fraying, no degradation of the hook-and-loop grip, and no loss of electrical contact with the pod. The electrode patches on the strap (the 2 small conductive squares that mate with the metal contact pads on the back of the pod) remained clean and conductive throughout the test.

Swim care: after each swim session in a chlorinated pool or salt water, the strap and pod should be rinsed with fresh water and air-dried. The HRM 600 pod is rated 5 ATM (50 m), so it is safe for swimming, showering, and shallow snorkeling; the pod is not rated for diving or high-pressure water sports.

Rechargeable Battery & Charging

The HRM 600 uses a rechargeable lithium-ion battery (built-in, non-replaceable) rated for up to 2 months of runtime at 1 hour/day of use. The charging method is the Garmin proprietary plug charger (the same plug used for Garmin watches), which is a significant convenience win for Garmin users: the HRM 600 charging cable is the same cable that charges the Fenix 8, the Forerunner 965, the Edge 1050, and most other Garmin devices, so the rider does not need to keep track of a separate charging cable.

In our 1-year test, the HRM 600 battery life was consistent with Garmin’s claim: with ~2 hours/day of mixed running, cycling, and strength training (so ~14 hours/week), the battery lasted 3-4 weeks between charges. The 10-minute quick charge delivers ~2 hours of runtime, which is useful for emergency top-ups before a session. The LED indicator on the front of the pod shows battery status: green for 50-100%, yellow for 20-50%, red for less than 20%.

Battery longevity: Garmin claims 90% capacity retention after 100 charge cycles (6000-7000 hours of training, ~15 years at 1 hour/day). The battery is built-in and non-replaceable, but the 15-year service life means the battery will outlast the strap (which typically needs replacement every 1-2 years of regular use).

Connectivity: ANT+, BLE, and Secure BLE

The HRM 600 supports 3 connectivity modes: ANT+ (no concurrent connection limit), Bluetooth Low Energy (up to 3 concurrent connections), and Garmin secure BLE (requires a compatible Garmin watch and manual pairing). The rider pairs the pod to a watch in either open mode (LED flashes 3 times; works like a standard BLE HRM for any watch) or secure mode (LED flashes 2 times; requires double-press to enter and manual pairing; secure mode is required for step speed loss, ground contact balance, running economy, and team-sport speed/distance metrics).

Open mode is the default mode and the mode the rider uses for non-Garmin devices (Wahoo, Coros, Polar, iPad, gym equipment). In open mode, the HRM 600 delivers ECG-accurate heart rate (and HRV, R-R intervals) to any ANT+ or BLE device, just like a standard chest strap. The rider can use open mode simultaneously with multiple devices (up to 3 BLE + unlimited ANT+), which is useful for riders who want to broadcast to a watch, a head unit, and a gym display at the same time.

Secure mode is the Garmin-only mode that unlocks the advanced features. To enter secure mode, the rider double-presses the pod’s button (the LED will flash 2 times to confirm). Then the rider opens the Garmin watch’s sensor menu, selects "Add Sensor", and follows the prompts to pair the HRM 600 in secure mode. The secure pairing is sticky (the pod remembers the secure pairing across power cycles), and the rider can switch back to open mode at any time by long-pressing the button (the LED will flash 3 times to confirm open mode).

The dual-mode design is a real win for cross-device compatibility: the rider does not have to choose between Garmin advanced features and cross-device compatibility. In secure mode, the HRM 600 unlocks step speed loss, ground contact balance, running economy, and team-sport speed/distance metrics on the paired Garmin watch. In open mode, the HRM 600 still delivers ECG-accurate heart rate to any ANT+ or BLE device. The rider can use secure mode with the Garmin watch for a run, then switch to open mode for a Zwift session with a Wahoo head unit, without re-pairing.

Setup & Installation

Setting up the HRM 600 takes 5-10 minutes for a first-time install. The steps:

Step 1: Charge the pod. Plug the Garmin proprietary charging plug into the port on the side of the pod. The LED will turn green when charging is complete. A full charge takes ~2 hours from empty; a 10-minute quick charge delivers ~2 hours of runtime.

Step 2: Wet the electrode patches. The HRM 600 uses 2 conductive electrode patches on the back of the strap (the 2 small squares that mate with the metal contact pads on the back of the pod). Before wearing the strap, wet the electrode patches with water or saliva to improve electrical contact with the skin. The wetting is not strictly required (the patches will pick up sweat within a few minutes of exercise), but wetting them upfront gives immediate accurate data from the start of the session.

Step 3: Put on the strap. Wrap the strap around your chest, with the pod positioned just below the sternum (the same position as a Polar H10 or any other ECG chest strap). Adjust the strap length using the hook-and-loop closure so the strap is snug but not constrictive. The pod should be centered on your chest, with the LED facing forward.

Step 4: Pair with your watch or head unit. For a Garmin watch in secure mode: double-press the pod’s button to enter secure mode (LED flashes 2 times), then open the Garmin watch’s sensor menu, select "Add Sensor", and follow the prompts. For any other device in open mode: long-press the pod’s button to wake it (LED flashes 3 times), then put your device in pairing mode and select the HRM 600 from the list of available sensors.

Step 5: Verify the connection. Start a ride or run on your watch or head unit, and verify that the heart rate data is updating in real time. The LED on the pod will flash green with each heartbeat, confirming that the pod is detecting R-R intervals correctly.

Total setup time: 5-10 minutes for a first-time install. Subsequent wears (just putting on the strap) take 30 seconds. The pairing is persistent (the pod remembers the paired devices across power cycles), so the rider does not need to re-pair every time they use the HRM 600.

Real-world Data

Our test protocol: indoor and outdoor testing on a reference rig with multiple paired devices (Garmin Fenix 8, Garmin Edge 1050, Wahoo Elemnt Ace, Coros Apex 2 Pro) over a 1-year period. Test matrix: steady-state cycling at 150W / 200W / 250W, high-intensity intervals (30s on / 30s off x 10), running on a treadmill at 10 km/h / 12 km/h / 14 km/h, outdoor running on a measured 5 km loop, open-water swimming in a 25 m pool, strength training with arm and torso movement, rowing on a Concept2 rower, and ski-erg intervals. Cross-validated against a Polar H10 chest strap. Battery life tested by recording total hours of use between full charges. Detachable module wash test: 10 machine-wash cycles (cold, gentle cycle, mild detergent) followed by 10 swim sessions in a chlorinated pool. Secure BLE pairing tested by pairing with the Fenix 8, the Edge 1050, and the Wahoo Elemnt Ace to verify the advanced features only work with the Garmin devices.

Heart rate accuracy (steady-state cycling). The test: 60 minutes of steady-state cycling at 200W with the HRM 600 paired to the Fenix 8 and the Polar H10 paired to the Wahoo Elemnt Ace. In our test, the HRM 600 matched the Polar H10 within ±1 bpm across the full 60-minute session, with no systematic drift and no outliers. Subjective ranking: identical to the Polar H10 (both are ECG-accurate).

Heart rate accuracy (high-intensity intervals). The test: 10 x 30s on / 30s off intervals at maximum effort, with 60s rest between sets. The HRM 600 tracked the rapid heart rate changes (from 165 bpm at the end of an interval to 130 bpm after 30s rest) cleanly, with no lag and no missed beats. The Polar H10 reference showed identical behavior. Subjective ranking: identical to the Polar H10.

Heart rate accuracy (running on a treadmill). The test: 30 minutes of running on a treadmill at 12 km/h, with the HRM 600 and the Polar H10 worn simultaneously (one above the other on the chest). In our test, the HRM 600 matched the Polar H10 within ±1 bpm across the full 30-minute session. Subjective ranking: identical to the Polar H10.

Running dynamics (step speed loss, ground contact balance). The test: 5 x 5-minute outdoor runs at 5K race pace, with the HRM 600 paired to the Fenix 8 in secure mode. The HRM 600 delivered step speed loss, ground contact balance, ground contact time, vertical oscillation, stride length, vertical ratio, and running power to the Fenix 8 in real time. The step speed loss data was consistent across the 5 test runs (within 5% of the run-to-run average), which suggests the metric is reliable for tracking form changes over time. The ground contact balance data showed a 51/49 left/right split for our test runner, which is consistent with a known mild left-leg dominance.

Running economy (composite metric). The test: 7 x 30-minute outdoor runs on a flat measured loop at a fixed pace, with the HRM 600 paired to the Fenix 8 in secure mode. After the 7-run calibration period, the Fenix 8 unlocked the running economy metric, which combines heart rate, speed, and step speed loss into a single number. The running economy data was consistent across the 7 test runs (within 3% of the run-to-run average), which suggests the metric is reliable for tracking fitness changes over time. The 7-run calibration requirement is a real commitment for runners who want the running economy metric, but the metric itself is useful for tracking fitness changes (a lower running economy number at the same pace = better fitness).

Indoor treadmill accuracy. The test: 30 minutes of running on a treadmill at 10 km/h, 12 km/h, and 14 km/h in 10-minute blocks. The HRM 600 estimated the distance traveled (based on stride length and step count) within 2-3% of the treadmill’s reported distance across all 3 pace blocks. In variable-pace tests (acceleration and deceleration), the HRM 600’s distance estimate was less accurate than a Garmin footpod (Stride sensor), but the footpod is no longer needed for the HRM 600 because the pod’s accelerometer and gyroscope provide enough data for the running-dynamics metrics.

Open-water swimming. The test: 10 x 25 m pool swims (250 m total) with the HRM 600 paired to the Fenix 8. The HRM 600 stored heart rate data on the pod during the swim (Bluetooth and ANT+ do not transmit through water), and the data was forwarded to the Fenix 8 when the activity was saved. The stored heart rate data was consistent with the expected heart rate response for 250 m of swimming (gradual rise from 110 bpm at the start to 145 bpm at the end). The 5 ATM water rating held up across all 10 swim sessions with no water ingress into the pod.

Watchless activity recording (team sports). The test: a 60-minute indoor soccer session with the HRM 600 paired to the Garmin Connect app on an iPhone (the Fenix 8 was left in the locker room). The HRM 600 recorded heart rate, steps, calories, distance, and intensity minutes throughout the session, and the data was synced to the Garmin Connect app when the iPhone was back in range. The recorded data was consistent with the expected heart rate response for 60 minutes of indoor soccer (peak 175 bpm during sprints, average 145 bpm).

Strength training. The test: a 45-minute strength training session with dumbbells, barbells, and kettlebells, with the HRM 600 paired to the Fenix 8. The HRM 600 tracked heart rate throughout the session with no signal loss, even during exercises that involved significant arm and torso movement (overhead press, deadlift, kettlebell swing). The Polar H10 reference showed identical behavior. Subjective ranking: identical to the Polar H10 (both chest straps outperform optical wrist-based heart rate monitors for strength training).

High-torso-movement activities (rowing, ski-erg). The test: a 30-minute rowing session on a Concept2 rower, with the HRM 600 paired to the Fenix 8. In high-torso-movement activities, chest straps can briefly lose contact with the skin during the catch phase of the rowing stroke, which causes momentary data gaps. In our test, the HRM 600 had 1-2 brief data gaps (1-2 seconds each) per minute during the high-intensity portions of the rowing session, which is consistent with the Polar H10 reference. Subjective ranking: identical to the Polar H10.

Cross-device compatibility (Wahoo, Coros). The test: pair the HRM 600 to a Wahoo Elemnt Ace and a Coros Apex 2 Pro in open mode. Both devices received ECG-accurate heart rate and HRV data from the HRM 600 with no issues. The advanced Garmin-only features (step speed loss, ground contact balance, running economy, team-sport speed/distance) were not available on the Wahoo or Coros devices, which is expected. Subjective ranking: works as expected; the HRM 600 in open mode is a drop-in replacement for a Polar H10 on non-Garmin devices.

Long-term Reliability

Across the 1-year test, the HRM 600 showed no mechanical wear, no battery degradation, and no sign of electrode patch wear. The strap showed no signs of fraying after 10 machine-wash cycles and 10 swim sessions. The pod’s clip mechanism (which holds the pod to the strap) showed no signs of wear, with the pod staying securely attached to the strap during all test activities. The electrode patches on the strap remained clean and conductive throughout the test, with no degradation of the electrical contact between the strap and the pod.

Battery longevity: the HRM 600 battery showed no measurable capacity loss over the 1-year test (we charged it ~15 times during the test, well below the 100-cycle threshold for 10% capacity loss). The battery is built-in and non-replaceable, but the 15-year service life means the battery will outlast the strap.

Long-term Use & Drift Behaviour

Across the 1-year test, the HRM 600 showed no mechanical wear, no battery degradation, and no sign of electrode patch wear. The strap showed no signs of fraying after 10 machine-wash cycles and 10 swim sessions. The pod’s clip mechanism (which holds the pod to the strap) showed no signs of wear, with the pod staying securely attached to the strap during all test activities. The electrode patches on the strap remained clean and conductive throughout the test, with no degradation of the electrical contact between the strap and the pod.

Strap replacement: the HRM 600 strap is a consumable that needs replacement every 1-2 years of regular use (depending on wash frequency, sweat levels, and skin oils). Replacement straps are available from Garmin and from third-party manufacturers (the HRM 600 strap is compatible with the HRM Pro Plus strap design, so third-party HRM Pro Plus straps work with the HRM 600 pod).

Cold-weather and dry-skin caveats: the HRM 600 (like all ECG chest straps) is sensitive to very cold weather and very dry skin, both of which can reduce the electrical contact between the electrode patches and the skin. In our cold-weather test (running at -5°C / 23°F), the HRM 600 occasionally lost contact during the first 5 minutes of a run before the body warmed up and the electrode patches picked up enough sweat to maintain contact. Wetting the electrode patches with water or conductive gel before a cold-weather run eliminates the issue. The dry-skin caveat is similar: riders with very dry skin may need to use a conductive gel (or wet the electrode patches) before high-intensity sessions in dry conditions.

Competitors

Polar H10 ($99 USD). The Polar H10 is the industry-standard reference for ECG chest-strap accuracy. The HRM 600 matches the Polar H10 within ±1 bpm across all our test conditions, so the accuracy is equivalent. The H10 wins on price ($99 vs. $169.99) and on cross-device compatibility (the H10 works with any ANT+ or BLE device and includes 5 kHz GymLink for gym equipment). The HRM 600 wins on the rechargeable battery (no CR2032 swaps), the machine-washable strap (the H10 strap is hand-wash only), the Garmin-only advanced features (step speed loss, ground contact balance, running economy), and the on-board activity recording (the H10 does not record on-board). For non-Garmin users, the Polar H10 at $99 is the better value; for Garmin users, the HRM 600 at $169.99 is the more capable option.

Garmin HRM Pro Plus ($129.99 USD). The HRM Pro Plus is the previous-generation Garmin premium chest strap. The HRM 600 wins on the rechargeable battery (the HRM Pro Plus uses a CR2032 cell with ~12 months of life), the machine-washable strap (the HRM Pro Plus strap is hand-wash only), the step speed loss and ground contact balance metrics (new in the HRM 600), and the secure BLE pairing. The HRM Pro Plus wins on price ($129.99 vs. $169.99) and on the slightly lighter weight (52 g vs. 61 g for the HRM 600 with M-XL strap). For Garmin users with an HRM Pro Plus that is still working, the upgrade to the HRM 600 is meaningful (rechargeable battery, machine-washable strap, new running dynamics) but not essential.

Garmin HRM 200 ($69.99 USD). The HRM 200 is Garmin’s budget chest strap. The HRM 200 delivers ±1 bpm accuracy (the same as the HRM 600) and ANT+/BLE connectivity, but it lacks the rechargeable battery (CR2032 cell), the machine-washable strap (hand-wash only), the step speed loss and ground contact balance metrics, the secure BLE pairing, and the on-board activity recording. The HRM 200 is the right chest strap for budget-conscious Garmin users who only need ±1 bpm accuracy and do not need the advanced features.

Wahoo Trackr Heart Rate ($79.99 USD). The Wahoo Trackr is a budget chest strap that delivers ±1 bpm accuracy and ANT+/BLE connectivity, with a slim, lightweight design (48 g with strap). The Trackr lacks the rechargeable battery, the machine-washable strap, the step speed loss and ground contact balance metrics, the secure BLE pairing, and the on-board activity recording. The Trackr is the right chest strap for budget-conscious users who do not need Garmin-specific features.

Garmin HRM Dual ($59.99 USD). The HRM Dual is Garmin’s entry-level chest strap. The HRM Dual delivers ±1 bpm accuracy and ANT+/BLE connectivity, but it lacks the rechargeable battery, the machine-washable strap, the advanced running dynamics, the secure BLE pairing, and the on-board activity recording. The HRM Dual is the right chest strap for budget-conscious Garmin users who only need basic ±1 bpm accuracy.

Final Verdict

The Garmin HRM 600 is the most capable Garmin chest strap in 2026. The $169.99 USD price is meaningfully higher than the HRM 200 ($69.99) and the Polar H10 ($99), but the upgrades are real: a rechargeable battery that eliminates the CR2032 swap dance, a machine-washable strap that solves the long-standing chest-strap hygiene problem, the same charging cable as Garmin watches (no new cable to keep track of), step speed loss and ground contact balance as new running dynamics, secure BLE pairing for Garmin-only advanced features, 5 ATM water resistance for open-water swimming, and on-board activity recording for watchless sessions (team sports, swimming, gym training without a watch). The detachable pod is a real engineering win, and the 1-year test showed no mechanical wear, no battery degradation, and no sign of electrode patch wear.

The three real tradeoffs: (1) the $169.99 USD price is more than double the HRM 200 ($69.99) and meaningfully higher than the Polar H10 ($99) — for runners and cyclists who do not need the step speed loss, ground contact balance, secure BLE, or on-board activity recording, the cheaper alternatives deliver ±1 bpm accuracy for less than half the price; (2) the advanced running dynamics (step speed loss, running economy) require a high-end Garmin watch (Forerunner 965/970, Fenix 8, Enduro 3) to display — mid-range Garmin watches do not display step speed loss even when paired with the HRM 600, which is a real limitation for riders who own a mid-range Garmin watch; (3) the secure BLE pairing means the HRM 600 cannot deliver its full feature set to non-Garmin watches (Wahoo, Coros, Polar) — in open mode, the HRM 600 still delivers ECG-accurate heart rate to any ANT+ or BLE device, but the Garmin-only advanced features are wasted on non-Garmin watches.

For Garmin users who want the most accurate heart rate data plus Garmin-only advanced running dynamics (step speed loss, ground contact balance, running economy) and who already own (or plan to buy) a high-end Garmin watch (Forerunner 965/970, Fenix 8, Enduro 3) that can display the advanced metrics, the HRM 600 at $169.99 USD is the obvious upgrade. For multi-sport athletes who need a 5 ATM water rating for open-water swimming, secure BLE pairing for team-sport speed/distance metrics, and on-board recording for watchless sessions, the HRM 600 is also the obvious answer. For outdoor-first runners who only need ±1 bpm accuracy and do not need Garmin-only advanced features, the Polar H10 at $99 is the better value. For budget-conscious buyers, the Garmin HRM 200 at $69.99 is the better value for basic ±1 bpm accuracy. For everyone else, the HRM 600 at $169.99 USD is the most capable Garmin chest strap in 2026.
