I hunt in west central Illinois (traffic setup, sometimes X fields) and am looking to run a 2nd caller for the first time this year. Our main caller is a 4 speaker setup (2 additional speakers can be added). The second caller is also a 4 speaker setup. I've scoured the forums and read conflicting information on just how to setup with two callers. My original plan was to place the secondary caller downwind and play a track that emphasizes on single barks instead of ground murmur. This call would remain ON, all the time. Then, our main caller would be placed around our blinds/backboards and play the ground noise/murmur tracks. This caller would on/off intermittenly as birds are working. Am I on the right track? The caller near our blinds/backboards, should the speakers be in front of us, behind us or both? Should the speakers of both callers be pointed in several directions or pointed upwards? Lastly, with this system, where would you put your motion? Thanks for any input. Really enjoy this forum.
