Hey guys I have been using this electric call for a few years now with great results. Before I had it in a duffel bag. I would set it out there and unzip it. It worked great but not the look and function I was going for. The Call Uses a P.A. Speaker, amp and your Mp3 player. Take a look at the final version of the eCall. Everything is water tight. There is foam cut outs on the inside to prevent your amp and MP3 player for bouncing around and getting beat up.

I'm also going to be making the exact same thing in a snow camo and then also a desert type camo. 1 for all seasons
