My personal feeling, is although smart tabs help some boats to get on a plane, and give stern lift, the manually activated tabs (Bennet, Boat Leveler, Lenco) are far more versatile and give you lots more utility. You can balance the boat from side to side, you can trim for the best fuel economy and ride. The "smart tabs"--which are not really "smart" at all, just cannot do this. Spend a few more bucks and get the system which will give you the most.
