Another Hac 4 question

rsprenkle said:

First has anyone noticed a difference in wattage inf between the watch and hactronic? i.e. On my first ride the watch info gave me an average of 147 and max of 408 but hactonic listed my avg and max as 124/329. Second question is being new to heart rate monitors I had my hac4 at work today and periodically it would pick up a heart beat eventhough the transmitter was at home. Is that interference?

Any insights would be helpful. Thanks.

Also I am having trouble starting and stopping recording I push both the UL and LL but simutaneously but it does not work most of the time is there a trick I don't know?

unfortunately i cannot answer your questions as i am having similar difficulty...do you know if the transmitter can be mounted to pick up data from the rear wheel?

Probably not it can only be 60 cm or 25.4 inches from receiver.
