I have used the doe bleat both early archery and later in the gun season with varying results. I have had bucks come busting thru the brush ready to throw down and have had does come in cautiously looking for the source of the noise. What made this call even more effective is this. Carry a spray bottle of straight not in heat doe pee. If you see a buck down wind spritz the doe pee into the air. My son called in 3 bucks at one time using this technic and I've called in a number of bucks using this.
