TL;DR: Upgrade your ruler with the Rollova 2.0 Digital Ruler, on sale for $76.99. As of Feb. 17, use code MEASURE18 to score 35% off the original price.


If you still keep a standard ruler around, here’s a digital alternative — one that’s probably a bit easier to store in a toolbox.

The Rollova’s OLED screen helps you get accurate measurements in an easy-to-read format. It can measure both curves and lines, and can also fit into your pocket. The ruler even features a data-saving function that can store up to 99 measurements. 

As its name suggests, you simply roll it over the distance you want to measure to get your reading. It can measure up to 10 meters in metric mode (centimeters) and up to 83 feet in imperial mode (inches).

Normally, the Rollova 2.0 digital ruler sells for $119, but for a limited time, you can enter the code MEASURE18 at checkout and take this baby home for just $76.99.
