It's not a Lowrance, but here's what I came up with for Daddy's boat. He was tearing transducers off the back of the boat most every trip to the stump filled swamps of Santee cooper. This rig has been unscathed on his boat for over two years. It's just two pieces of channel nestled together. There's a spring to hold it in the lowered position and a lock pin to hold it in the raised position.
