12 gauge with number 4 buckshot or BB shot, works for me out to about 50 yards or so. pattern your gun.
no such thing as cover scent. we have had coyotes spook when they got to the spot we walked in on and we wear knee high rubber boots.
there are some nice beginner electronic calls out there for about 40 bucks but the range is limited(cass creek or western rivers) . you buy a good used / new foxpro for about 150.00
