DIGITAL HEIGHT GAUGE, from Rockler Woodworking and Hardware, offers the precision (0.001" accuracy) of a digital caliper in an upright form, according to the company. A solid steel base holds the gauge in place so the user can position the jig with one hand, set the caliper to the desired height, and then raise the bit or blade to match. The digital height gauge has an adjustment range of zero to 5" and can be zeroed out by setting the caliper at table level and pushing a button. The gauge offers readouts in inches and millimeters. The battery-powered Rockler digital height gauge, item 30980, sells for $49.99. Contact: Rockler Woodworking and Hardware. Tel: 877-762-5537. www.rockler.com
