#2080: MirrorMeter

Today’s invention is a tape measure with two reels on board, as shown.

This allows the distance between two points (A and B) to be measured precisely without the casing (green) getting in the way.

It also means that by allowing the reels to slide into contact with each other, the tape when pulled from one side will emerge to the same degree from the other.

This would facilitate location of the mid point of AB exactly, which can be a useful time saver, especially within a restricted space.
