Maximum radius about 70cm. $70.00.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe problem with a board compass is not drawing the circle - it is the pivot moving halfway round. Three suction cups fix the pivot to the board so the arc closes where it started, which is the entire difference between a demonstration and an apology.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe turning handle\u003c\/strong\u003e means one smooth motion rather than a series of short pulls, and a smooth motion is what makes a circle look like a circle from the back of the room.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIt takes whatever you write with.\u003c\/strong\u003e A round pushing device grips anything from 6 to 18mm in diameter - chalk on a blackboard, a marker on a whiteboard, round or square edged. No proprietary refills.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAbout 70cm maximum radius\u003c\/strong\u003e, so a 1.4 metre circle - a full board on most classroom whiteboards. A scale shows the angle of the feet, so you can set the same radius twice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck your board first.\u003c\/strong\u003e Suction cups need a smooth, non-porous surface. They hold on glass, melamine and painted steel whiteboards. They will not hold on a chalkboard with any texture, or on a board with a worn matte surface.\u003c\/p\u003e","brand":"MTA Essentials","offers":[{"title":"Default Title","offer_id":53793081164139,"sku":"EVWIS10911","price":70.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/2795\/8891\/files\/wis10911_drawing-compass-with-feet_v1_2.webp?v=1788358635","url":"https:\/\/megaofficesupplies.com.au\/products\/whiteboard-drawing-compass-with-suction-feet","provider":"Mega Office Supplies","version":"1.0","type":"link"}
