In the case of hunters, the clothing may not be distinguishing, there may be several others in the woods wearing the same color, but it will give us an idea how hard they will be to spot. In most eastern states hunters are required to wear blaze orange outer clothing during the firearms season. This makes spotting them much easier in the woods. Bow hunters and turkey hunters are intentionally much harder to spot in the woods. Every year the manufactures market a new pattern of camouflage that is guaranteed to make you invisible in the woods.
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.
