Someone was recently asking about this caller, and Walmart had the Predator-1 on clearance for $25 so I grabbed one to test it. It is made by Hunter's Specialties, comes with the caller itself, a remote with 5 preprogrammed sounds (baby bird, cottontail, puppy cries, rodent, & woodpecker), a lanyard for the remote, and it even includes the batteries. The remote has a belt clip in addition to the lanyard. The caller has a large clip so you can hang it on something, a pivoting speaker so you can set it up in multiple positions, and also has a small ring on the side of it so the remote can be clipped to the caller for storage. First impression is that this caller is a great bang-for-your-buck! The whole unit is compact and lightweight, the remote is easy to use, and the volume is more than loud enough to call in the critters. There is little to no lag time between the remote and the caller like some other brands. The remote allows you to mute the call, but the volume level is located on the caller instead of the remote (my only complaint). The sound quality is far better than I expected. I have yet to see how long the batteries will last or how far the remote will really reach out (the package indicates 50 yards), but I think it would make a great first e-caller for someone who's on a budget. For now I'm giving this caller 2 thumbs up.
Hopefully I'll get a chance to test it in the field in about a month or so and I'll be able to give a little more info on it.
