Re: handled GPS consumption while in achor watch mode?
The garmin 76cs that I use as a back up has very good battery life...I've never used it for an anchor alarm, but I'm pretty confident that it would get you through a nights sleep, if you started with fresh batteries. The only thing is that if you keep it in the cabin it could lose it's signal. It needs a reasonable view of the sky, since the antenna is built-in.
I wouldn't mind having an IPad.
