Re: [the666nurse] outdoor watches
I have the X10 and i have used it on skydives plenty of times. the altimeter works fine in that environment but i have not used it in a base environment.
The X10 is great for hiking. good gps features to compliment movement across land but not so great at air travel. it will track your coordinates and altitude but it will not export them to a map to show a flight path or at least i never was able to get it to do that. it just shows it like you walked around on the ground.
very pricey if you intend to just use it to track WS jumps. if your just using it to get to the exit point then its a great watch to have.
