## Description

Martin breadth caliper offers accurate breadth readings for chest, shoulder, pelvis, etc. The 20-inch scale is marked in both inches and centimeters For Students' educational purposes.

Review: Great value. - For a hobbiest on a lathe they are just what I wanted.
Review: Shoddy construction - Why did you pick this product vs others?: I needed something with a deep reach for measuring wide pieces. This fills the bill with a 10” depth and expands to nearly 19” wide (although without the 10” depth at that spread) As you can see in the photo the depth gauge is misaligned, so the numbers will not be accurate. Close enough for what I’m doing, but if you require precision don’t buy this. It is so cheap that country of manufacturing does not appear anywhere on the gauge. Wow.

## Questions & Answers

**Q: I want to measure the diameter of a rock sphere.  What is the largest diameter that it can measure?**
A: I'm guessing you could measure a little over 14 inches before the scale guide would hit (the wider the span, the shallower the depth).

**Q: The description indicates 11" and above, does that mean the caliper can't measure anything smaller than 11"?**
A: It will span from zero to about 22 inches, but be advised that the scale is not accurate. I span what I'm measuring, set the lock and then measure the span using a Milwaukee tape measure with a magnetic tip.

**Q: I know the width/thickness these can measure up to 20" but how long are the arms? I'm trying to measure thickness pretty deep on a board.**
A: For an item of 5/8" thick, it will reach a depth of approx 10".  For an item of 2" thick, it will reach at depth of approx 9".

**Q: can this tool be used to measure tree diameter or is it for mechanical uses only?**
A: Small trees I suppose.
