I fish, hunt, and work in the Maine woods. There is a lot of lonely country up here. When I heard about the onX app I was skeptical, I'm not really a "techie" guy. One of my buddies was showing it off one day and it looked pretty good so I downloaded the free app. Long story short, it didn't take me long to buy a membership!
I use this app for everything! I use it to find remote trout ponds, navigate back to the truck after tracking a buck all day, scout for bird covers, map out snowmobile routes, track mileage on hikes and hunts, track distance on canoe trips, you name it! If I can keep a charge on my phone I am golden!
The only improvement I could possibly suggest would be the private property ownership layer. In Maine it's a little sparse, however they may already be working on that...
Anything that helps me to save a step or two in the woods is a keeper and this product has saved me thousands! Like I said, The Most Useful Tool I Own.
