Does anyone have one of these?
Bennett Auto Trim Control
Once the Zero point is set all you do is turn it on and it maintains that trim.
Setting the Zero Point. After installing the system, take your boat for a test run. When underway, use the manual trim tab control to get your boat running at the best running attitude. Press and hold both “Set Zero” buttons (Sun and Moon Buttons) on the ATC Keypad (about 4 seconds) until the blue LED flashes rapidly. After the LED is flashing, release the buttons. Your boat’s attitude is now set in the memory.
The problem I see, at least from my experience, is you would have to re-set the Zero Point quite frequently for different sea states and speeds.
With that said, I think it would take a lot of the guess work out of maintaining optimal trim once you get use to it, especially for long trips at constant speeds.
I’m sure there’ll be lots of speculation amongst use and that good, but sure would be great if someone here has actual real-world experience.
