Seco Prism and GPS pole adjusting jig

Convenient for adjusting and calibrating pole vials in the office before sending into the field.

The adjusting jig features an ‘L-bracket’ to rest the prism pole point on and simple thumb wheel on the top bracket to adjust the pole position.

Use the thumb wheels to level the bubble, rotate the pole 180°, adjust out half the error on the thumb wheels and the rest with the bubble adjusting screws.
