I have an older 62s with the Trax west chip that I still carry just to track position and find my way back if needed but I use my phone and the Onx system. I hunt all over the western states and generally pack in and stay for days at a time. Airplane mode and a charge bank is all a guy needs. I really don't need the handheld gps just havn't given it up yet. The best part of Onx is you can really see the country before hiking all the way in and not really knowing.
