I purchased a Sports Instruments Pro 9 HRM about a week ago. I chose it for its wide range of features, which, I have to admit are pretty impressive (i.e. Five HR zones, time spent in each zone, average HR, dual timers, memory, etc.) Problem is reception. If I hold the watch in front of me, it picks up the signal just fine. If I hold the watch 90 degrees to my side or even just on my wrist at my side, it completely loses the signal. I've replaced the batteries in the sensor and the watch to no avail.
Is this normal, or do other brands have issues like this too? This pretty much means I can't even jog with it. Are there other units with 5 zones?
