Centra duplex

- significant improvement of the aiming accuracy

- minimizes aiming errors

- Allows the attachment of individual centerring ring sizes or an centerring iris

- individual adjustment of centering ring (iris) distance using stepless length shifts on the lens shade

- compatible with the centra-rear-sight "SPY" and in combination with "LENSHOOD II" (MEC FREE-SIGHT, centra SIGHT BASE, FWB diopter and older Anschütz diopter)


Aiming with micrometer peep sights and front-sight-tunnel, a nearly optimal solution.
But even nearly perfect solutions can be still improved. In competitive sports, each point counts. Especially during aiming appear minimal tolerances, which are due to the jamming of the front-sight in the iris-apperture. If the front-sight not exactly in the center of the iris-apperture, the shot will miss the bulls eye.
The shooter have to take maximum care to avoid mistakes in this case. He have to be concentrated in each shot, that his eye is exactly in the middle of his rear-iris. In challenging light-conditions and for longer series, it´s very heavy to make no errors.
The DUPLEX is an additional centering-unit, whitout burdening the concentration. The resulting intermediate ring, warned the eye more clearly when an error appears.
A real challenge was the positioning of this additional ring concentric in the sight-line.
The result is an X-Y adjustment-unit, the DUPLEX.
