The Draftex DC737 Quickbow Compass has a quick adjustment feature that is activated by depressing the two levers on the legs.
This releases the locking system so that a large or small radius can be set very quickly. The release of the levers locks the legs in place and fine adjustment is made with the central wheel.
Gears in the head of the Draftex DC737 compass ensure that both legs maintain an equal distance from the centre.
Adjustable knee joints serve to keep the pencil point or extension bar at the proper angle to the drawing surface when the compass is either fully extended or adjusted to a small radius.
