HRM with GPS on

As per title, has anyone noticed a huge dip in heart rate recording whilst using GPS? specifically playing golf? I noticed my average HR for the game was 55! didn't return to a more normal number until the game was ended on the F5

Not really, change the HRM battery maybe?

Ensure the device is snug tight to the point it cannot move up and down your wrist but not so tight as to limit circulation
Wear watch on outside of wrist, away from wrist bone

I can confirm that it was user error, sun tan lotion to be exact (so rare we need it in the UK)
