Just so I'm up to speed. Are the compasses on these new GPS units electronic? I would be concerned about that for more than one reason. Reliability? Accuracy? If it is electronic and the batteries die,you no longer have any means ofnavigation from there on out.

For a little background, I've been navigating in the woods with GPS and compass since GPS came on the market years ago. I wouldn't carry one without a hand held compass. Even if the GPS fails, you can still get out that way.

Interesting thread.
