When used on top of tripod provides quick and simple centering on reference points. Parallel shifts of 100mm vertically and 30mm laterally.

ILLUMINAI UK-

Get greater accuracy from AT-G series Provides light to the telescope reticle

engineering auto levels. In one kilome- when available light is insufficient, for

ter of double run levelling, accuracy is example, in tunnels or at night.
