There's an adjustment screw behind the older(previous gen) mantis dynascope. This model:

What's that screw for? When I was cleaning lenses, I noticed that this screw tilts a mirror.



btw...I was investigating and turned the screw to the point of 'boing!'. The mirror and screw have separated.. I have to take the mantis apart again to reattach.. :(

The side adjustment is for eye separation. The back adjustment (just a screw) I suspect is for horizontal alignment. (People generally don't have one eyeball higher than the other..)

It took me an hour to fix. :( Yup.. It's a mirror adjustment screw that is not meant to be loosened too much otherwise it detaches from the mirror. But also, I discovered there seems to be a missing metal clamp that helps to hold the same mirror in place. One side of the mirror has a fastener clamp, the other side doesn't. (The mirror holder is loosely screwed into slotted plastic.. Bad..) (Missed assembly at factory,this was tampered with before or the clamp popped off and I can't find it.) So the only thing keeping the mirror from falling was 1 screw!

Fixed both problems.. Works fine.
