FAR CONVENIENCE, SHORT FLEXIBLE, YOUR IDEA MEASURE MATE.
IT IS SMALL AS A BIG TAPE AND DOES MORE THAN THAT
Unlike traditional tapes, you can finish calculation quickly with addition or subtraction among difference length, multiple measurements for area and volume. You can also measure the height by the Pythagorean.
The best part is the size is not as big as a monster, it is still fit your hand. Throw all your tape measures, folded tape away, only bring the TIO30 with you, it measures all you need.
