Most laser measures solve one problem — accuracy — while creating another: you have to remember to bring them. They live in a case, in a bag, in the car. There when you plan ahead, missing when you don't.
The Cooper Ray was built around a different idea. At 1 ounce and 2.68 inches, it clips to your keychain and goes everywhere you do. It's the world's smallest laser measuring tool: ±2mm accuracy, 100-foot range, 7 measurement modes, zero setup. For contractors, realtors, designers, architects, and serious DIYers, it's the pocket backup that becomes the tool you reach for first.
No More Two-Person Jobs
The Cooper Ray measures the full distance of a room from a single position. No helper, no walking to the other end, no tape that retracts while you're writing. Point it at the opposite wall, press the button, and you have a reading in under a second.
It also auto-calculates area and volume. Two measurements gives you square footage on-screen, no calculator. Three gives you cubic footage. For material estimates — flooring, paint, drywall — the math is done before you put the device back in your pocket.
Precision Laser Engineering Inside
Cooper has been building tools since 2012. Inside the Cooper Ray's aluminum alloy shell: a precision laser emitter, optical lens, ST computing chip, and sealed lithium battery. The Class 2 red laser outputs less than 1mW — FCC, CE, and UKCA certified, Class 2 eye-safe. The backlit display shows large, clear numbers with a toggleable backlight for low-light environments.
Specs: 1oz / 28g — 2.7 x 0.87 x 0.55 in — 100ft / 30m range — ±2mm accuracy — 7 measurement modes — 3 units (m / ft / in, true decimal inches) — front/rear reference switchable on-screen — 5,000 measurements per charge.
Three Buttons. Every Function. Zero Downloads.
No app. No account. No Bluetooth. The Cooper Ray has three buttons, and that covers everything. For a realtor mid-showing, a contractor on a job site, or a designer in a client walkthrough, that matters — you press a button, get a reading, and keep moving.
7 modes: single distance, continuous distance, area, volume, and three Can't-Reach modes (Measure from Far, Both Directions, Measure Middle). The Can't-Reach modes let you triangulate dimensions where you can't physically access one endpoint — practically useful on real job sites. Reads in inches, feet, or meters.
No Batteries. Ever.
Sealed lithium battery. USB-C charging. One hour to full. 5,000 measurements per charge. Smart auto-shutoff at 20 seconds (laser) and 60 seconds (device). No replaceable batteries, no compatibility questions, no dead device at the wrong moment.
Built for the People Who Actually Need It
DIYers, contractors, realtors, designers, architects. At $24.95 it comes with USB-C cable, wrist lanyard, and keychain clip. Ships in zero-plastic eco-friendly packaging. Backed by Cooper since 2012.
Always With You
A tool that's on your keychain gets used every time it's needed. A tool that stays in a case gets used when you remember it. For professionals who move between sites, properties, and client spaces, that reliability matters more than any single spec.
