Luthier's Digital Caliper

Always one of our most popular items when we exhibit at luthiers conventions!

Our Luthier's Digital Caliper combines precision, ease of use, versatility and an attractive price, but its usefulness for fret work makes it special.

Customized for fretwork!
We added a custom jaw notch for accurately measuring fretwire crown height (the height above the fretboard). This is essential for comparing new wire to original wire. And thanks to a great idea by repairman Frank Ford, we've also added a notch on the depth gauge to measure fret height on the instrument—a real time saver.

  • Measures fret height before AND after fret installation
  • Accurate readouts in inches or millimeters
  • A must for all precision guitar work

Handy for lots of other measuring jobs in the shop—nuts, saddles, tuners, tool setups and more—this caliper has long-life stainless steel jaws. Featuring LCD digital readouts in inches or millimeters, it measures outside, inside and depth dimensions up to 6" (154mm), with super-accurate .0005" (.01mm) resolution. The jaws can be locked at any position.

LR44 battery and durable plastic storage case included.

Great tool. Accurate.

(Customer's Reviews)

Accurate and cool features for measuring frets. A bit pricy but I am satisfied. I have to lock the jaws with its screw whenever I turn it off because it turns on esaily when unlocked (shortening the life of the battery). Plastic parts feel like weak but work fine.

Very good but battery life is too short.

In general I think this is a fine product, however I think there are some issues with the electronics. I had to have my first on replaced due to problems with the battery compartment; unit would not stay on or constantly reset itself. Several other unit at school were having issues so I think it was just a bad run or job lot, the tool itself is great!
