Just getting into calling yotes,have called some in but only see their tracks when I leave the stand I have made a startling innovation.
I bought the Cass Creek e-caller and wanted more volume so I got a musical horn and 40' of cable from Radio Shak and it works ok for the money. But what happened next shocked me.
I remembered my De Walt work radio had a CD jack on it and went over and plugged it in,turned it on and hit the coyote pups button on the Cass and it scared me on 1/2 volume.I turned it up and hit it again and my wife came running out mad as a hornet cause of all the noise.
What I have is a pretty clear caller loud as any drunken brother in law for $20 plus the radio,Now if I get a CD with a remote I can call them in from Mars.Try it you'll like it.Get your cables at RadioShak you need male plug on each end one was $7 and the other was $3..
all the best,
