Recently found this site and have been trawling though it. Seems to have a lot of great stuff on it.
Just the other day i bought a Pro Trek PRT70, my first one, i have a few G shocks but got this on sale and have always wanted one with altimeter and barometer function. My query is this, both the altimeter and the barometer seem to be all over the place, At the same geographic location the altimeter varies 100m or more. I keep resetting it but within a few hours it is out again. The same seems to happen with the barometer.
I don't know if any one has this watch but it also has a barometer graph on it, which takes readings every 2 hours for the last 18 hours, this graph is meant to show the barometric readings but mine seems to stray all over the place. And I have several points on the graph with missed readings. The watch is notably better if I take it off my wrist and leave it on the side but its meant to be a watch not a desk top display. I don't do anything abnormal with it just walk around the house etc.
Any help would be most appreciated. Thanks.
