I saw this yesterday and thought it could be kinda interesting for a boat application. Obviously it wasn't made for it, but just might work. I have had zero time to read up on it at all, so maybe it wouldn't work, but I'd think it probably could. It could be a great tuning tool if you don't have a track to test at. My biggest interest came when I saw the price tag....right at about $1500. Any thoughts on how or if this would work or be of benefit?
