To carve an archtop instrument you need fast, precise measurements of critical top and back thicknesses. Our caliper does the job with just a flick of your thumb.
This high quality caliper is designed specifically for luthiers, with a deep 9" (228mm) reach to accommodate an archtop guitar, mandolin, violin or viola.
The metric dial indicator is accurate to 0.01mm for thicknesses up to 25mm. It has an adjustable zero point, and can also be positioned for left-hand use. You can install the removable brass foot for convenient freestanding operation, or take your measurements freehand; the sturdy lightweight aluminum frame is easy to handle.
