Big game hunting with firearms can itself involve several variables. The firearm can be a rifle, a shotgun, a handgun or a black powder weapon. For SAR purposes we can pretty much discount this method, as one missing member of the group is usually found by the rest of the group in short order. Bow hunters are more frequently by themselves in the woods and as well hidden as they can get. The most common method used is tree stands, but those who opt for remaining in contact with tera firma will usually do so in some type of blind, a commercial version or one constructed on the spot using bushes, etc.
Turkey hunters are worse to find than bow hunters.
They seldom climb trees. Their preferred method is to hide in a blind of some sort on the ground. Duck and goose hunters are seldom the cause for a search. These are the folks who sit in a blind or a boat, over a spread of decoys and making honking noises to lure their quarry within shotgun range. Most of them hunt with a faithful companion who leaves their side only to retrieve the kill.
