Martin Audio Wavefront Precision Rigging Inclinometer

The ASM20017/ASM20019 are Martin Audio's rigging measurement tools for the Wavefront Precision line array range (WPC, WPL, WPM, WPS), used to confirm the splay angle set at each hinge point against the array's DISPLAY 3 prediction before a show. The ASM20017 is the inclinometer assembly that mounts to the array; the ASM20019 is the companion reader used to take the angle measurement.

Both are sold separately so a touring rig can carry spares of the wear item (the assembly) without replacing the reader.
