I've been using the Inreach's for many years, it is a device that is on the top of my gear list, way above high tech clothing, packs or boots, I'm an older fella that primarily hunts solo in the backcountry and the Inreach has proven it's worth time and again, I use it for communication with my family, checking in, showing them where I am at all times, we've had emergencies at home I wouldn't have known about without it and also to let friends and family know I've got that bull down or whatever, also works for some lesser navigation if needed. I use my phone paired to it and texting and the basic maps are easy. For actual mapping I use my phone with Basemap and Onx which works well enough except that I have to keep the location on for them to work. Yesterday, in the backcountry bear hunting, my oldest trusty Inreach gave up the ghost, no power up, tried all the reset tricks, contacted Garmin etc, My question is for all you Garmin users is I'm trying to choose between the Inreach Explorer, or the Garmin 66i, which comes with true navigation, much better maps an SD card slot for other mapping such as Onx and so on. Anyone have experience with both, or at least the 66i? Any input would be awesome, my wife and I have an agreement, NO Inreach, no solo hunting. So you can see my situation, it's bear season haha. Thank you.
