So question to hand held GPS users:
1. Can you use Google Maps to identify coordinates to a spot and enter those into the unit and name them? My use case is cherry picking quarries from google earth and being able to drive to the area (guided by the unit), park somewhere close (as close as possible) and hike to the quarry. So from beginning to end (and back) directional guidance to a particular spot.
2. Do these hand held's allow you to expand the screen (like a cell phone) if you have a map of the area up so that you can get more precise and see some topo detail?
3. FYI - I cannot use a phone, there is no service in these areas.
4. If you were going to buy maps for it - what are lessons learned? Everything I'll be on is public. I see "hunting maps", blah, blah, but what map/vendor would you load if using this for fishing pits in strip mine country? You can't see them from the roads for the most part.
5. What's your experience with battery life and/or bad experiences with losing satellite connections?
Thanks for any insight. I've read a bunch of descriptions but most yak about the technology and not the use. Easier the better is best for me.
