never been a fan of too much technology in the boating environment other than perfect pass. what I see here is one more thing to remember to tell someone driving the boat when riders switch(if you're like us and turn the engine off during switchout to allow fresh beers/pee breaks/etc and avoid unneeded hours on the boat). We all know it's hard enough to find someone that can give you that "perfect" tow that you, as the boat owner, provide to everyone on board. one more thing to try and teach them.
