This is a high quality compass with automatic adjustment lever and jointed legs. Fast estimated adjustment is made by adjusting a lever found on either side of the leg. Finer adjustment is made by using the strong center spindle.
The extension bar can be attached to allow for circles up to 600 mm in diameter. The pencil adapter also takes pencils, coloured leads or Indian ink refills up to 11 mm in diameter. Comes ready to go loaded with 1 lead, and with a small plastic vial with 2 spare leads.
This compass would be appropriate for an older child studying geometry, a teenager or an adult.
