I have around a 40 bpm resting hr. The TriHRM like all Garmin HRM's doesn't activate until over 80bpm. Useless for anyone with a good heart, because a low intensity workout may not bring our hr up enough to pop the straps min hr threshold. It's useless for those of us with a good heart trying to record pre/post workout hr's and also for warmups and cool downs. The Fenix 5x will however the HRM is advertised it can be used solo and then sync to the watch, which it does when it actually records hr, but not before the 80bpm threshold. The Fenix 5x says hr in a pool may not work and says use the chest strap, but if my heart rate is too low the workout (usually beginning) is not recorded if I only wear the hr strap because my bpm was too low to wake up the strap.
Why doesn't the strap start working as soon as it detects HR, if I put the strap on I want it to record hr or I wouldn't have put it on in the first place? Why is there an 80bpm threshold? Probably because this cheep garbage can't detect hr under 80bpm.
It's not a battery thing unless you all are wearing your HR straps around as a fashion accessory to look cool when not working out? No? Are not a retard trying to look cool? Ok then. The device should detect HR when put on no matter what the HR rate. NO ONE wears a chest strap around that DOES NOT want hr recorded... that's why they put the strap on in the place; to record god damn hr. Why do you think they put the chest strap on in the first place you morons? It feels good? Moral support? Fashion? Garmin is run by Idiots.
Edit just to mock Garmin for their incompetence and irony: The trihrm and Fenix 5x are the two most expensive offerings in their class by Garmin. They are advertised for athletes, and those serious about fitness. They are not considered "amateur" device like $50'fitbit garbage "trackers". I guess Garmin doesn't know athletes bodies very well; ironic for a company selling some of the most expensive health trackers on the planet marketed at athletes. What next is Garmin going to make a deal with fast food companies to offer Garmin fitness users discounts on quarter pounders, super sized sodas, and large "fatty" fries? Because every athlete needs a Myocardial infarction now and again.
