Read full product description


This wand is used during a tangent screen test.

On a tangent screen, test objects are inserted into the fabric leaving only the object visible. Half turn rotations obscure the test object behind the wand. Alternating the rotation, objects can be made to disappear and reappear for a confirmation response.
