OK, I know there is a world of expertice and opinions out there concerning boat alarms. Give it to me all, from the simplest and least expensive, to the most elaborate (though thatll be out of my price range). My 06 Puma w/275 Verado (my “new” boat) needs protection. Any “slick” homemade alarm set-ups out there? Those would probaably be in my price range. Thanks!
