Guys I do it good enough with my natural voice too,I just really wanted to see if the thing really worked or not because as GC pointed out I believe that it is another gimmick!That silence is deadly locator call was an absolute joke.On more than one occasion we blew it at birds we could see in the field and they never even looked up.Maybe it was broke but how the hell do I know I could'nt hear a thing with it!! <img src=icon_smile_wink.gif border=0 align=middle>Thats why we got to ask if they really work or not. <img src=icon_smile_big.gif border=0 align=middle>
