This is where I am right now : choice is between these two.
They both have : Heartrate, bike features, altimeter, thermometer, cadence, download on computer, ...
The HAC 4 also has power (but it looks to be more of a guess than actual measurement). On the other hand, you don't pay more to have this information. So price is an advantage on the HAC 4.
720i seems to have more accruate power measurement (but way more expensive), better possibilities with setting heart zones and you can download workouts directly from the computer.
Another advantage of the 720i over the HAC 4 is that you have a 4 sec. sampling rate (only a 20 sec. sampling rate for the HAC 4, which is the most disappointing feature on the HAC 4).
Does anybody use these computers or have more information on either of them ?
Thks a lot,
Laurent
