Description

The QuadGrade Sonic Tracker is an efficient and economical plug-and-play solution designed for creating consistent crossfalls on undulating surfaces. 

It is perfect for applications such as curbs and gutters, sidewalks, driveways, and cycleways. 

The device can trace a string line, conform to concrete formwork, or grade match to an existing surface.

Unlike most other manufacturers, It can run on either the left or right side of the blade.

You are also able to set a control zone so that any obstacles around the string line or formwork are excluded from its grade height datum reference.
 
The QuadGrade Sonic utilises the same coiled cables and sensor ports as the QuadGrade lasers, making it straightforward to set up and calibrate. 

It is compatible with all SharpGrade and SharpBlade leveller models, including the new SharpGrade R grader blade.
