Ball prism with drop guard/carrying strap

For working on walls, a base with an integrated magnet should be used. This holds the sphere prism securely in the base and allows it to be appropriate. After removal from the base, it is "parked" on the magnet integrated at the frame corner.

To completely eliminate the possibility of an accidental fall, the following spherical prisms are also available with a drop guard as standard.

They are clipped onto the triangular frame with a quick connector.
