The #6600-04 Small Tilting 25 mm Mini Prism is constructed of yellow Delrin and operates on two axes just like the #6600-01 and #6600-03. Unlike the other two models however, this model features a 25 mm mini prism in place of the reflector material. The prism has a -17.5 mm offset.
The mini prism allows for ranges up 2,000 ft (600 m) or more with most instruments.
