Bennett AutoTrim Pro f/Electric Trim Tabs - AP000A1BC

First impressions of the AutoTrim Pro and 6"x12" Bolt tabs on our Four Winns H180 ... After the first calibration procedure the AutoTrim Pro worked for putting the tabs up and down during acceleration and deceleration, but did not correct for listing. After a second calibration everything worked correctly. The calibration step for accelerating in a straight line is difficult to perform. It took several times before it would flash the LEDs after acceleration. Not sure if I needed to, but I started from scratch each time that step did not work. Setting the FAV button is also something that takes some experimenting to get the auto mode to work just as you want it to; not using too much trim and not using too little. One thing to note is that it does not correct quickly for listing. Every few seconds it makes a small (incremental) adjustment to the trim tabs. It keeps doing this until the FAV setting is reached. It can take 10 to 20 seconds on our boat. Another thing to note is if you are testing the list correction by shifting weight to one side (leaving the helm in the process), the boat will start turning enough that the auto mode will not make any adjustments. All in all I am very pleased with this system and would recommend it, but in order to get it to work correctly you have to follow the calibration procedure exactly and if the unit does not flash the lights like it is supposed to on any calibration step, start over and try again. One other thing ... The first calibration was in relatively calm water (by my definition). The second one was in calm water. That may have made a difference as well.
