As a turkey guide I don't know how I made it without onX. I use it to pin point birds and look at the topography to find the best way to move on a bird, especially on new ground that I'm not familiar with. There is a little learning curve trying to figure out all the features and navigation but as you play with it it's easy enough to learn. Over all its a great tool that I will continue to use I'm even considering upgrading to the elite plan so I'll have all 50 states.
