Don't forget about the voice recorder for quick field notes, easiest way I've found for keeping track of what goes at each set. I just put it in the book when I get home.

Oh, I use the camera mostly for that but yeah, another good use. Actually the fact that my phone is smaller than most cameras is basically already a must have use lol.

Your camera has a scratch and sniff mode ?

Whoever mentioned the license aspect is spot on. I’ll pull it up and have it ready when I enter an area with no service. When tagging game where needed I’ll even fill out the form online and take a pic to verify it’s done. This helped in Florida this year with both the license and tagging. Pulled out the phone and showed the GW license and where I’d tagged the bird and he was on his way.

Just slide the little bar over on top less than a second its silent. IPhone. Don't know about others

I have my ringtone set as crickets. I have been in a tree before and forgot and my phone rang. Deer didn't even lift their head. It was TOO COOL!!
