I have that call. Its a lohman mouth yelper. I have used it successfully on a couple of occasions to bring birds in that last 50 yards when I didnt want the movement required for using my slate call. I kindof use this as a last resort call if the birds dont respond to anything else. I also have the lohman pump yelper which I also use to get initial responses from gobblers. The pump yelper is great for pissing off the hens to. It seems to aggravate them more than any other call Ive used. I wouldnt use these calls by themselves, but they have definately benefited me by having them in my vest.[:-]
