>>119277Right... Been outside and messed about with it.
It seems fairly accurate with the altimeter, and it'll display your current coordinates (though it took a while to find 'em). It won't display a map or anything. And the compass seems to work but only digitally in 8 steps (N, NW, W, etc).
Certainly wouldn't want to rely on it to navigate by, but as a compliment to a proper map/compass it'd be handy for finding yourself if you're not sure exactly where you are.
First time I've used it though, and it was kinda confusing. Have a peek at the PDF manual if you want to know more.
