I was trying to buy the Bushwhacker and talked to them at Johnny Stewart. They are having trouble getting the remote to function consistently at 100 yards. They will not release the caller until they know for sure that it works consistently at that range. So, they do not think it will be available for consumers until around January 30. I want the Bushwhacker, after researching all of the different callers. So, I bought a new battery for my old 512 cassette and I will wait until January 30 or maybe, since the season will almost be over, I will wait until next fall and buy a Bushwhacker after all of the "bugs" have been worked out.
