Just wondering if anyone can help me out with this question. I am wanting to invest in a handheld gps unitto mark stand, trail, camera locations, etc, but i dont know if they have them that have google earth type maps ??? Is there such a thing that could be updated when google earth updates its maps ??? Terrain changes with controlled burns, timber cutting and thinning, pipelines and highlines being built all over. Anyone that has any input, it would be greatly appreciated.
