Features & Benefits
Patented Angle Compensation Indication - automatically calculates and corrects the grade display for the angle of the dipper arm when excavating allowing the operator to check grade in multiple locations without moving the machine
Check grade with the dipper arm extended to or retracted up to 30 degrees
Four selectable accuracies – allowing for rough or precise work
Center on-grade provides an equal amount of grade information above and below on-grade when used with dozers, mini-graders, levellers and drag boxes
Offset on-grade provides more range above the on-grade position using the entire receiver to avoid over-digging
Robust and built for jobsite environment – 2 year warranty
