A Telescopic Alidade is an instrument used to obtain the bearings of an object, along with other information. Telescopic Alidade is a sophisticated device, which gives accurate bearings. The optical system simultaneously projects the image of the compass card, together with a view of the spirit level, onto the optical view of the telescope. By this means, both the object and its bearing can be viewed at the same time through the Telescopic Alidade eyepiece. Our Telescopic Alidade has been tested extensively and found to be very accurate.
