I need to install a new depth system, seriously considering a fishfinder (Garmin FF 140) with the display at the helm. . . thinkin' I could fabricate a base made of Starboard to mount between the pedestal and the compass. . . while thinkin' about this project I saw that the popular way to mount instrumentation seems to be on a pedestal guard; my boat does not have a guard - should it? seems they wouldn't add much protection, just a convenient mounting platform for your instruments. . . is adding a pedestal guard a good initial project?
