Binoculars aren't always used for seeing what's faraway. A low power pair can be very effective for picking apart brush, I've spotted more than one deer in thick laurel that I would not have seen without using binoculars to disect the area.
To the o.p. Asbel's book on ground hunting is very good. Covers still hunting, stalking, ground blinds and temporary blinds, as well as info on scouting and a bit on tracking. It's directed toward bowhunters, especially traditional bowhunters, but if his techniques can get you close enough for a longbow kill, they will certainly work for a traditional muzzleloader.
