Report Review for product Caliper - Digital, highly-accurate for luthiers

The Digital Luthier Caliper is NOT accurate enough to measure instrument (Dulcimer, Guitar, Banjo, etc.) string size. It needs to be able to accurately measure to the thousandths of an inch, ie .014 , 012 , .011 or .010 . There is a large difference in string vibration pattern and string harmonics based on string size and length. One must select string size depending on the desired vibrating string length. Unfortunately, this instrument as well as similar instruments in this category, luthier or not, are not acceptable in this role.
