I use paper maps when I'm not in checker board for several reasons:
In the back country I don't need extra charging packs or electronics, just a light weight map and compass that won't die. Plus, if I start ranging I don't have to worry about whether or not I downloaded the area ahead of time. Secondly, looking at a big picture gives you a lot more SA on the area than just a small screenshot. Thirdly, when your hunting buddy asks for tips for his next hunt you can pull out your maps that look like an art project with scouting notes for unprecedented street cred.
