I have two helix 7s, and am looking for a way to keep the cables organized and protected from dirt/water while my units are removed while im duck hunting. Would this do the job? Theres not really a good description on the humminbird website and on other websites i looked at it, it looks like it has wires coming out of the other side so it may serve another purpose. If this wont work do yall know of anything that would? Thanks
