Those condos look great. My father and I just began to put four crappie condos together. I will post pics from when I put them in the water. We are making ours out of pvc and it looks like a tree. With 2 1/2 ft pvc branches and it is 5 ft tall. I have a question, will most fish finders be able to pick up pvc pipe? I assume so, but just wanted to ask.
