Query: The AnglePro feature is useless

While the auto leveling feature works fine (checked with a 4' level and a water level at 34'), the AnglePro function is off by about 3 degrees (at 8 feet it's off by 4") which is plainly visible just by eye.I haven't decided if I'm going to return it or take it apart and see if I can adjust it. Also as already mentioned in another review, the center mark is very hard to see. I might try to paint it with thinned out model paint (if I don't return the unit).
