Precise Digital Caliper, Measures up to 4"/100mm

One of my favorite tools! Once you start using this very precise caliper you won't go back to other forms of measurements. Not only does it measure the outside of items but the inside too, which is incredibly handy. Measure objects up to 4" or 100mm. 

One excellent feature is if you forget to turn it off it shuts down automatically but instantly comes back to life when you measure a new item. It slides easily. LR44 battery is included and you'll find it has a very long life.

You can quickly switch from Imperial to Metric also.
