Digital calipers are an absolute essential. Here at SparkFun we use them all the time. These premium calipers come with an extra battery and auto shut-off. Measurements can be taken in either metric or standard. The calipers are 6" in length and make a great addition to any tool set.
This assortment of tools is great for those hackers who need a portable tool assembly with plenty of room to add your own. We’ve found our favorite, low-cost and easy to transport tools, and created a kit that we would give to our local hacker friends. While these tools might not be enough for more heavy duty use, they should be just what you need for a project on the go.
