Best GPS topo map and aerial photo source.
 

Me and I few buddies just picked up the new Garmin Rino 650. now we need to purchase some maps. What is the best source for topo's & aerials? Also, is there any software that shows tax map lines to ensure we stay on our property. we'll mainly be using these in the North East NY region.

secondly, if we purchase the maps, software, etc. can it be loaded to more than one unit or will we have to purchase 3?

sorry for the newbie questions this is my first hunting GPS.

thanks

You can go online and download all kinds of free maps and stuff on your gps. Just search free gps addons and find the ones that you want. I have yet to find one that will show me the state land/private land borders but will keep looking.
