Looks like they are going the right direction on the control head, but I wish they weren't keeping the "S" shaft design. Also it looks like probably the typical ACE/AT foam grip, which I don't hate, but it doesn't feel modern or quality and I find a pain to clean.
I am curious about the coil. New size, good for large open fields and in trash. It is either a medium size coil (but then how is it a new size?), or it is a new shape maybe. A narrow, long coil that covers a lot of ground heel to toe, but is narrow side to side to read a narrower slice of the ground at a time?
Iron volume adjustment sounds like they are going after a lot of the newer mid-priced units with a similar feature. I would say this is not an ACE replacement. The question is where does it fit with the AT series? And is it waterproof?
