Looking for best option on handheld GPS with mapping software for Prince William Sound. We love to hike around the Islands and Mainland areas in PWS but find its easy to get turned around. Iíve not been able tie down good mapping software that has useful cartography for this area. The mapping software on my boat is great for the water but really useless for land. I guess if we just use the GPS for tracking that would help, would be nice to have something with more detail.
