I have a johnny stewart digital preymaster that I have had very good success with. I use an extra length of speaker wire so I can set it out about twenty yards from me, and it sounds pretty good even at full volume. The thing I don't like about is that you set up, unwind the wire, decide to move, re-wind the wire. It is a hassle and usually ends up in a big birds nest. I currently wrap it around a small coffee can and drop the control in the middle of the can to protect it. If anyone has a better way I would love to hear it. I keep checking out the Foxpros and have to keep convincing myself I don't need it. Can you imagine setting that thing at 100 yards upwind and letting it call! The yotes would be circling right into your lap! But they are sooo expensive. I could get another gun for the price of those things.
