I have used the non remote preymaster, Minaska Bandit, Western Rivers Predation, and currently the older foxpro 532B. With the exception of the Minaska coon sounds (they rock by the way), I have had the most success with the Johnny Stewart sounds which are the sounds put on the Preymaster and other Hunter Specialties calling units. If I was to go out right now and buy a remote caller, it would be the Preymaster PM4 remote unit hands down. It is well priced, has good range, is dependable (they got the bugs worked out from the earlier models), and the sounds are hard to beat.
