According to 945 owner's manual, lactate threshold test "requires a Garmin® chest heart rate monitor". Do I really have to have a _Garmin_ strap here, or does the test work with any compatible ANT+ strap?
I am planning to buy a Polar H10 strap, and would like to ensure that this test will work as it should. I understand that e.g. the running dynamics metrics are limited to certain Garmin straps, but what about the HR related performance measurements -- will I get them with Polar strap as well?
