First setup I had ever used this call, I had a coyote coming in within 1 minute. He was 200 yards out when I first spotted him. He was working to try and get downwind and did the usual stop at about 75 yards to size things up. I flipped the call over to the mouse squeaker and was able to get him to move in another 20 yards out of some cedars. One shot one kill.
Used the call on our 3rd setup of the day. Again within the first minute I had a coyote coming in across a pasture that was 1/2 mile away. The coyote had to traverse a fairly deep canyon and when it came out of the canyon it was at 225 yards and not in a good shooting spot. I flipped over to the squeaker side and she moved in a bit to a clear shot lane. One shot one kill.
This call is now permanently on my lanyard as a go to call.
