This is my first post and I'm a real novice so please go easy on me.
After much deliberating I've bought a Vector, primarily to use the barometer function as I'm a keen fisherman. According to Google Earth my home in North West England is at an elevation of 171m, so this is what I set the reference altitude to. Right now however, at the exact spot where I set this the altimeter reads 200m. Why is this? I have also noticed that the barometer reading is typically around 10-15mbar below the reading of the nearest weather station I can find which is some 10 miles away from me but at an elevation of 65m. Right now my watch shows pressure at 986 mbar whilst the weather station claims current pressure to be 1004. I have tried to read the manual but sadly very little of it makes sense to this fisherman.
I'm also surprised to see how difficult it is to find details of elevations for places in southern ireland, where I'm away to at the weekend and suspect I really need to re-set my reference altitude to my base whilst over there?
All help or suggestions gratefully received - great site BTW.
