We recently bought a 2004 Larson Cabrio 240. It has an 8'6" beam, which is going to take some getting used to after having a 10'6" beam boat. Obviously, every time someone moves you have to adjust the tabs. It seems we end up driving with our fingers on the buttons making constant corrections. 
We are considering installing the Bennett automatic trim controller (http://www.bennetttrimtabs.com/autotabcontrol.php?cID=4). If we understand it right, you trim the tabs to where you want them, turn on the automatic controller, and it takes over from there. Is that pretty much the case? Has anyone installed and/or used them? If so, do they work as advertised? Is it worth the investment?
