Anyone fishing with a Aluminum boat, Xpress, Triton, Fisher, Tracker, etc. This from Vexilar allows you to mount there transducer in the hull to keep from knocking it off with a log etc. Works in boats up to .15 thick. I have had one in my boat for 2 years without a problem. The only way to go if you fish out of a tin boat like me. http://www.vexilar.com/products/alumaducer.html
