The Almighty Ruler PRO™ 2.0 Review

The Almighty Ruler PRO 2.0 is what you buy when the base Ruler’s 131 ft starts to feel short and you want a screen that’s a pleasure to read. It keeps the 3-in-1 idea — laser, tape, and calculator — and turns up the two specs that matter most when you measure a lot: range and display quality.

Range you’ll actually grow into

A 393 ft (120 m) laser is a big jump. Indoors it’s overkill, which is the point — you’ll never bump the ceiling of what it can measure, whether that’s a long warehouse wall, a property frontage, or a multi-story stairwell. Paired with ±1/12 in accuracy, it stays dependable across that whole range.

The OLED screen is the headline

Most measurers in this class use a basic LCD. The PRO 2.0’s 1.3-inch OLED is brighter and sharper, with strong contrast that’s genuinely easier to read in a dim crawlspace or bright daylight. It sounds minor until you’ve squinted at a washed-out screen on a real job — then it feels essential.

Memory and battery

Memory for 99 measurements turns the tool into a notepad: take a room’s worth of readings, then transcribe them all at once instead of measuring-and-writing in a loop. And with around 3,000 uses per USB-C charge, it’ll go weeks between top-ups for most people.

Who should buy it

The PRO 2.0 is for the frequent measurer — a remodeler, a serious DIYer, a property manager — who measures bigger spaces and wants a screen that doesn’t fight them. If you mostly work indoors and measure occasionally, the base Almighty Ruler is the smarter buy and is actually a touch more accurate on paper. If you need professional features like a daylight-friendly green laser and app sync, step up to the Laser Tape Pro. Not sure? Start with the full lineup comparison.
