Hello folks,
Over the weekend I managed to acquire a Casio ProTrek (
http://www.amazon.co.uk/gp/product/B000NG45E8/ ) - I believe these are called 'PathFinder's' in the U.S.
I've been after one for a while, so was happy to be able to finally pick one up. Now apart from being great time-keepers (radio controlled, so always spot on), the interesting thing about these is the additional triple sensors they incorporate - a compass, a thermometer and most importantly a barometer (it keeps a log of the pressure every 2 hours for 24 hours so you can see what the pressure is doing on a small graph).
I've been tracking the barometer since the weekend against WeatherCat and after adjusting it for my altitude, it seems pretty accurate. The thermometer however is a different story as it's mounted on your wrist - this is great for the barometer (keeps it at a pretty constant temperature), but you have to take the watch off (and then wait half an hour) if you want to read the temperature.
I've calibrated the thermometer against a few I have here and it seems pretty accurate when off the wrist, but it's a pain seeing pretty much 30?C all the time when it's on your wrist.
So, my question is - does anybody else have one - any tips? It seems that as soon as you travel from one location to another, the barometer will need re-adjusting for any difference in altitude and the thermometer is next to useless on the wrist. I'm wondering whether it's worth trying to calibrate the thermometer 'on the wrist'?
Cheers,
Stu.
