LASER DESIGN INC.'s surveyor laser probes (SLP) are offered in two high-precision models (SLP-250, SLP-2000) that are faster and more accurate than their predecessors, with a laser line more than twice as long as competing probes. Both deliver virtually noise-free scan data as a result of proprietary advances in electronics and optics architecture. The SLP-230 has a 25-mm laser line length, the SLP-2000 has a length of 200 mm. www.laserdesign.com
