I used thinwall PVC for my inner pipe which was the perfect diameter to allow th transducer cable end to run inside eliminating having to deal with the cable picking up floating debris. I also added a"T" at the bottom which allows me to set the transducer inthPanorama positin. Other than that a simple ram mount to the boat like so many others. hope it gives you some ideas.Name:  IMG_1005.JPG
