I recently purchased a 2014 Hobie Outback Kayak for fishing. It came with the “Lowrance Ready” transducer mounting plate on the bottom, which is great, if you use Lowrance fishfinders and GPS. I don’t. I’m a Garmin guy, so I needed to figure out how to mount my Striker 4’s CV transducer in this area. There are people who make custom mounting plates using 3-D printing with carbon fiber, and these are between $25-$30. I am sure they are nice, but I came up with a solution for less than a quarter using an old AC outlet box that I could cut up. Any similarly sized piece of plastic (or metal) would also work, I just used what I had.
