I've been using the True Talker (Whitetail) not the (Western) for many years now and I personally think it is the best on the market today. Once you have gotten familiar with the different sounds the deer make, you can reproduce most all of them with the True Talker. I haven't missed a year in the last ten where I didn't call in a buck or more. Last year I got five. Go learn the sounds then try the true talker.
