[NEW] Cooper Ray Laser Measurement Tool

The world's smallest laser measuring tool. 1 ounce. 2.68 inches. Clips to your keychain and goes everywhere you do.

Built for contractors, realtors, designers, architects, and serious DIYers — the Cooper Ray delivers ±2mm accuracy up to 100 feet with zero setup. No app. No Bluetooth. No second person. Point, press, read.

No More Two-Person Jobs

• Area mode — auto-calculates square footage from two measurements
• Volume mode — auto-calculates cubic footage from three measurements
• 3 Can't-Reach modes — triangulate dimensions where you can't access one endpoint
• Continuous mode — tracks distance in real time as you move

Everything is built in. No app, no account, no Bluetooth pairing. The backlit LCD display shows large, clear numbers with a toggleable backlight for low-light environments. Reads in inches, feet, or meters — true decimal inches. Front/rear reference switchable on-screen.
