fox pro. I love my shock wave. oh and I also love my snow/crow pro
The shockwave has great sound and speakers for playing the digital sounds, but it's a bit big and heavy for the way I hunt... walking quite a distance to where I make stands. You make 10-15 stands a day, and the size/weight starts to drag on you.
I still have and use my old Fury caller. Just the right size. I've killed more coyotes coming to that caller than the plague.
