Luthier's Digital Caliper

Great Tool! Only one comment..

I'm terrible at doing conversions in my head. Since most people (at least most I know) express their action heights in fractions of inches (not tenths of inches), this tool would be perfect if it had MM/INCH/FRAC instead of just MM/INCH. Otherwise, it's a terrific piece of kit.

I initially bought this to measure fretwire, and it's VERY cool that you can use the depth gauge to measure the wire already on the fretboard. As a result of measuring some flat spots I was able to see that I really needed a refret instead of a fret dressing.

Humorously, as I was trying out the caliper I discovered that StewMac had mislabeled the fret wire they sent me -- they sent me the right stuff, but the 154 was labeled 149 and vice-versa. Hehe. Good thing I checked before installing =) So there's another use for it.
I subtracted 1 star because the other comments about the thumbwheel are totally right - I'm scared it's going to fall off every time I use it. Be careful and you'll be OK. Treat this as a precision instrument and not a sturdy tool. =)

It arrived just two days ago and it's been a great help so far. The little box to store is nice and the little details to help measure frets are really nice.

Haven't used a caliper for many years and reading those little lines did effect the accuracy and ease of measuring: with digital read out accurate readings are much easier. Not sure why instructions say to take out the battery: I never take out my watch battery and I don't wear it for months at a time; if it prolongs the life of the battery or will cause harm to the digital readout?

Great tool to have for all the measurements you have to take! I like the inches/mm feature especially!
Easy to use,very handy!

This product is great. We needed to find fret heights over an old neck that needed refretting, and the calipers gave us the readings we needed, exactly. Can't wait to use them on an upcoming neck and fret job.

I agree with Lance in Ohio about the thumb wheel.

As soon as I took mine out of the box and tried to open the jaws the thumb wheel broke off.

Its just a poor design.

Caliper can be used without it so its OK but just be careful of that if you buy one.

Other than that these calipers are great and specialized for guitar work so what can you do i guess.

This is an ok caliper. It is nice that it does all of the special measurements. However, the thumb wheel is only held in with a plastic loop and if you have the caliper locked an try to measure with it the thumb wheel will break off. So make sure your locking knob is loose before trying to measure anything.

At first I didn't like the design of the caliper. I felt it was a bit hard to use. Well then I learned how to use it lol! I have to say this is an essential piece to a luthiers workshop. If you're meticulous in detail & accuracy than get this tool. It's not intending for the tech who 'eyes' all his measurements. I actually use this to also measure cutouts as well.

You might as well pop for this thing. It does some specialized measurements that other calipers won't. Save yourself the time and frustration of trying to modify your own.
