The BERNINA Integrated Stitch Regulator (BISR)—an evolution of the BERNINA Laser Presser Foot BSR—is a revolutionary innovation in the BERNINA 990 that will transform your quilting experience. BISR automatically regulates stitches for a variety of quilting applications, including working with rulers. The integrated stitch regulator works automatically with the BISR 5.5mm sensor needle plate and all BERNINA quilting feet and accessories. Simply attach the needle plate and quilting foot to achieve perfect quilt stitches of consistent length at variable sewing speeds.
