Compact Machine Grade Control

The LS-B10 laser receiver delivers a versatile, low cost indicate solution for grade checking and machine control grade applications. Although similar to the LS-B3, it is much smaller and weighs 66% less…the lightest weight in its class! With its integrated magnetic mount, the LS-B10 can be easily installed on a vast array of machines. And with its small, lightweight design, the LS-B10 with Holder-6 is excellent for manual grade checking as well!


  • Machine control and grade checking capability
  • Lightest weight in its class…about 1 pound!
  • 4 on-grade zone selections (LED); coarse to fine grade for machine control
  • 11 LCD grade channels with 5 gradual triangles for out of grade indication
  • 270° detection range
  • Red and green LED indicators

The LS-B10 series provides cost-effective solutions for grade control on small machines such as backhoes, mini-excavators, skid steer loaders, and other compact equipment. The basic LS-B10 model features a magnet mount for quick attachment when used on equipment or can be combined with the optional holder for use on a grade rod.

The advanced LS-B10W offers built-in wireless technology and CANopen (Controller Area Network) connectivity to provide the ultimate in communications flexibility. The new RD-10W in-cab remote display brings grade information via wireless link in front of the operator – where it is needed most.
