Fits Brunson-type Transits
The 186 multiple paired-line target is machine-engraved on white plastic laminate. This target may be slipped over the objective end of Brunson-style transits (or levels) and used for non-illuminated auto reflection at distances greater than ten feet. The target is adjustable to allow for centering on the optical axis of the transit. Orientation of the target with respect to the instrument's reticle is accomplished by detente positions fitting into the pin found on our telescope barrels.
