I can tell that most of you guys are younger generation tech savvy hunters, and I applaud your expertise, but a friendly word of advice. NEVER go into the back country without a compass and topo map of the area you plan to hunt. Batteries fail, and charging devices do not work well with no sun. This system served us older hunters well when there were no smart phones or hand held GPS units.
I carry a compass, map, GPS, SPOT, and cell phone. If I could take only one, it would be the compass. FYI, even if you have no cell service, many times you can still send a text message.
