I said this before in another thread, but here it goes again. If you want to successfully call in critters consistantly you have to use the sound made by them. Mouth calls and other E-callers will work, but it really is the law of probability. You will have greater success by using REAL animal VOCALIZATIONS no matter what animal you are trying to call! Right now the best and ONLY true animal Vocalizations are available in the Wildlife Technologies E-caller. go to the web page and check out the master sound list www.wildlifetech.com IF you have never heard an E-caller from them, you will be amazed at the extremely loud and clear volume it has! Remember, it is your hobbie so why would you take the cheap route and buy a tool that is inferior. If you cannot justify the price (if you heard it you would) then wait till summer because I believe they are launching a smaller version of the current model for around $450. It will not be as loud as the current E-caller but it is still ten times louder than all it's competitors and not to mention REAL STUDIO GRADE ANIMAL VOCALIZATIONS!!!!!
