I've used onX extensively for a number of years. It keeps getting better. The latest and greatest for me has been the photo waypoints which I use a lot. The ability to download and use maps out of cell service is very useful. I would never go back to a handheld GPS unit. There's also a ton of research and information that can be had with the available layers before you ever get your boots dirty. Between hunting, guiding, hiking, shed hunting and forevermore looking over the next hill I use my onX more days than not.
