I finally used it when they updated to V4. Mostly Elk hunting with a little bit on the Antelope hunt. Worked flawlessly.
It still has a way to go on the web map side to be a stand alone solution for me. I have to be able to import geo referenced maps, primarily geopdf. If I need to convert, I can do that but everywhere I hunt has TMA's that are supplied as geopdfs and I need the ability to use those on the web for Internet Scouting as well as import those into the handheld. The SAT imagery and roads are good, the topo is a bit weak but I don't use that option so it's not a real concern. With the TMA's and limited open roads, I also need the ability to change colors of roads or at least have the ability to create a track over the open roads on the web map, transfer those to the app, then change the colors for better clarity. I believe most of that is coming in future updates.
