Garmin HRM 600

Advantages

• ✓HRM 600 provides HRV and advanced running dynamics that HRM 200 lacks.
• ✓Rechargeable battery lasts up to two months, whereas HRM 200 uses a replaceable coin cell.

Disadvantages

• ✗HRM 600’s proprietary charging cable adds a dependency not present with HRM 200’s simple battery swap.
• ✗HRM 600’s larger module depth may feel bulkier than the slimmer HRM 200 design.

Advantages

• ✓HRM 600’s rechargeable battery eliminates the need for periodic coin‑cell replacements required by HRM‑Pro Plus.
• ✓Detachable module on HRM 600 makes charging and replacement easier than the integrated design of HRM‑Pro Plus.

Disadvantages

• ✗Both share the same 5 ATM water resistance, so HRM 600 does not improve swim capability over HRM‑Pro Plus.
• ✗HRM‑Pro Plus may offer a slightly slimmer strap configuration for tighter fits.
