As awesome as that is, i cannot use that app where i usually hunt. There isnt any cellular service and it doesnt work unless there is service. At least for what i have went through. Thats why i use, or prefer, a gps unit that works with satellites. I wouldnt want to get into a dead zone and not be able to use it when i need it.Hookset;n610306 said:I do not know much about that area but I do use the onX hunt app for your phone instead of purchasing a GPS. Down load the maps and use just like a GPS. Works great.
