The app shows your current location and will show direction of travel while navigation to a waypoint.
The app is 10 bucks it will be the best 10 buck you spend for fishing. DCL has a decent amount of contour info on it.
hess is absolutely correct about this being the best 10 bucks you spend. I have had it now for 3 years and I use it everywhere, DCL, Lake Champlain, Lake Anna, Potomac River; and you can get routine updates, I believe that feature costs an extra few bucks, but I get updates all the time. I have it on both my iPad and iPhone, I prep with the iPad and carry the iPhone right out on the ice and walk right to my spots. Sweeeet.
