A Better Sense of Security
I feel much better leaving my boat in storage at the marina, knowing that it will be more difficult for a thief to steal my electronics. I got tired of taking on and off my 16-inch Lowrance monitor every time I put the boat away. Installation was not difficult, and the build quality is excellent.
