Wish I had got one of these ages ago. Beats using a ruler any day!

Well the first one I bought was not working, it turned on at will. SM replaced it without question, the next one I got was better but still turns on as soon as you touch it. Maybe it's working the way it should. Over all it works good a little pricey but they stand behind all their products, and that is priceless! Highly recommend this tool. I wish it came with some kind of learning chart.

These are good callipers. Solid to the touch, practical, metric and imperial measurement. A grub screw that is reliable. The on/off means the battery lasts longer. I bought a cheap pair from my local tool shop that lasted 5 months before the grub screw was stripped. The StewMac ones are far superior and a quality tool essential to precision work.

This is my first caliper. Not only does it help me make accurate measurements for my guitar and ukelele builds, but I use it for so many other woodworking hobbies. A great tool to have by your side. Thanks.

These are pretty average calipers. We found that they did not accurately repeat measurements, especially under .020. Find a used set of calipers, cut a notch in the jaw with a dremel wheel and you're there.

It's always hard to tell with these less expensive calipers until you get them in hand, so I was happy that the quality of this turned out as high as it is. not a real high-end unit, but certainly up to the tasks it's designed for. I've found the notch in the end of the beam particularly useful on one of my problem fretboards to assure myself that the high fret I found was a local backbow problem rather than poor leveling. Only thing I'd change is the case, which I'd prefer to have one snap-latch rather than two, so that it'd be easier to get into.

Problems of measurements were resolved with this tool. Recomended.

Awesome little tool. It's great for all sorts of things including checking the gauge of strings when customers don't know what sizes they use. It's quite awesome until the batteries start going out then it reads incorrectly. What puzzles me is that Stew-Mac does NOT sell the SR44 battery that this thing uses. Come on Stew-Mac! Grrrrrr.....

And usefull tool.

A must!! This thing goes beyond just fret setting.....a worth while expense......JCM
