5QUAD 4000
LINELOKR™TECHNOLOGY (LLT) AUTOMATICALLY LOCKS YOUR
LASER ONLINE AND KEEPS IT THERE UP TO 600 FEET AWAY.
LLT provides a two-way communication between the Quad 4000
Laser and the LineLokr Line Control Module for vertical control
applications such as plumb, squaring and line layout.
LLT allows you to setup your laser at one point and then merely
push a button to obtain line. The Quad 4000 and LineLokr
communicate via a special radio link causing the Quad 4000 to
automatically drive itself to centerline and lock onto your far
point. The Quad 4000 and LineLokr continuously communicate
to maintain centerline and will not drift off due to wind and
temperature changes throughout the day.
