First Impressions of the Fluke 414D Laser Distance Meter
Full disclosure, this is my first time using a laser distance meter and I’m hooked. The Fluke 414D has completely changed how I approach measurements on the job site. Super quick measurements can be made with this tool, and it automatically calculates area and volume in seconds – perfect for those heat load calculations where accurate room dimensions are critical.
