Luthier's Digital Caliper

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!

I like these but the battery life on my set is not great! I like the stew mac extra features but the battery life is low and I change it far too often!

The simple features that are added to this tool make fretwork and nutwork so much easier. The slots for measuring fretwire on/off the fretboard ... simple yet verry effective!

I've found them to be pretty accurate. Much better at reading string sizes than dial calipers. However, they feel really cheap for what you pay (no tool should have delicate plastic parts), and the auto turn on feature is terrible. You have to be so careful when putting them down because it will turn itself on and drain the battery. I'm not sure why you would need calipers to automatically turn on when you begin to slide them open. You should be able to turn this feature off. As far as I know, you can't.

is a very useful and good quality, the only fault I could find is that with the slightest movement of the head so it is very difficult to move it in its box without turning on automatically and runs on battery ....

Always on my bench!

just purchased this caliper. I was having trouble trying to get proper measurements on nuts and everything else. i have never used anything like this before. I am so pleased because it is so easy to use and soooo accurate. thanks

I Hand carve all my necks here at Neville Guitars, so when I get a order for a certain size neck,it makes it a dream to nail the correct size with these digital calipers.

Practical tool and very accurate.

Dead on accurate! Measures everything you need it to plus more. Another great tool from StewMac.
