I bought this watch and heart rate monitor for mainly basic heart rate monitoring during my workout the watch function works fine but the pulse monitor doesn't really work I tried many times to get it to work to no avail.You are supposed to put your finger on the sensor and it should pick up your pulse.
I assumed it would pick up my heart rate if using gym equipementwithout the need for a chest strap and haven't tried this yet.For the price as a day watch can't argue with this if I bought it for using as a watch which I didn't.
As the old saying goes, you get what you pay for !!
