It features an extra-wide beam capture sensor that also rejects annoying interference from strobe light exposures. The large and bright LCD displays (front and rear) feature 9-channels of grade information and digitally show
the distance to on-grade. By pressing the Hold button, the display is locked so the user can conveniently read the results. For added versatility, three colored LED’s and a strong magnet mount are imbedded for vertical operation, ideal for steel erection or operator
gradechecking while excavating. To assist in monitoring the Topcon rotating laser, alert icons appear on the LCD if the instrument is
disturbed (HI alert) or when the laser battery is low.
