I set mine just as I drop the anchor, and figure that's close enough to

me a little wiggle room, but will let me know soon enough if I move. I
also got a SPADE anchor that has only dragged once in four years of
cruising.


That's a good solution.

Personally, I don't trust gadgets like that and usually awaken every 2 ~
3 hours to look around when we're anchored out.

Our old old GPS has a feature where you can set an "alarm zone" and that
is what I'd use, but your method sounds simpler. One of these days we're
going to update electronics...
