I know when I had my Garmin installed by a rigging company he shut off the pinging while setting up cause it could damage something, but I thought that was because the concrete was just below it and being a hard surface it would do harm? Not really sure, mine was already wired for a Lowrance and that is what I run when I use the bow graph, it was set up to shut off power when you start the big motor. To be honest I only run that one sometimes, most days I just run my two on the console.
