iPhone plus OnX blows away all the GPS’s out there. I’ve used it in 2 states this year and last year without a single hiccup. Stand alone GPS’s aren’t even close in quality to what the IPhone can do for me. On a side note the Garmin Inreach models are awesome for sending text via satellite either to check in or in case of an emergency. You can keep your phone charged with a spare battery pack or one of these but if you keep it on airplane mode and only use it periodically the charge last a long time.
