Our goal is to help spark imagination and creativity through the unique gems we offer, be they pieces of Nature or the handy gadgets we find to work with them. Our product line of 'gadgets' includes our digital calipers, a butane soldering iron and an assortment of LED work lights, while our main line is in the rock, gem and mineral field of creativity. We hope we can help inspire passion and excitement within you for whatever you choose to create! To change the battery, just turn the caliper over so the LCD Display is facing down and the slider clamp screw is facing toward you (down), with the thumb roller up. Using the provided screwdriver, remove the screw on the same side as the slider clamp screw, using caution not to lose it since it is so small. Once the screw is removed, the battery cover on the opposite side will be loose and the battery will easily come out. Insert new battery with plus (+) side facing up. Replace cover, and while holding it in place, reinsert the screw and tighten. That’s it. Properly dispose of used battery. The owner's manual is included in the case when you receive your caliper. But if you would like it as a PDF just reach out to us and we will send it to you.
