Description

Tripod mounted prismatic compass with spot bubble, ball and socket head for levelling, spot bubble and small telescope.

Circle graduated to 2°. Diametrical circle reading. Circle interpolation to 0.1-0.2°.

Features a horizontal motion clamp and a slow motion screw.

Wild did advertise a newer model of the B3 in 1986. The newer model allowed the clamping of the circle to the base, thus allowing the use of the B3 as a simple measuring device for horizontal directions. (See WILD brochure G1 426e)
