i have a very cheap unit ($10) that i bought for a infrequently used MTB. it has a function that my older units did not have, and i REALLY like now 🙂
it can be set to "scan" thru all the bike functions on a rolling basis, displaying each for about 5 or 10 seconds before switching to the next. current > trip > odo > max > avg > time. over and over, again and again.
do most of the newer units have the scan function?
especially any of the units including HR like polar or hac4?
