Yes, the bubble/s are probably not adjustable. Someone bought me one of
the 'cheapies' and it's pretty primitive but the laser can be seen over
a hundred feet. Beam spread is a problem, but I'm going to make it a
little tripod base with three setscrews to use on a project I have.
I'll probably put some correction marks on the bubble vial to true it
up. I have several surveying instruments that can be used to set the
bench marks, then I'll set the laser level to the BM's.
