WHREE LED reflector with a 5 m long line, 5V/1A USB powered. - Purpose: Check where the dent is on the surface of flat metal by aligning the reflected lines on the board to the dent. - How it works: Use bright sun to illuminate the surface. The reflection distorts at the dent, then you can work your PDR tool behind the dent to even the distortion. When the distorted lines become parallel in the reflection, the dent is removed. - Benefits: Enables precise dent location, guides PDR work, and is effective under natural outdoor light. - Specifications: 5 m long line; 5V/1A USB power; LED reflector design for outdoor use. - Outdoor use: Convenient when working outside with natural light; check the dent location when you are unsure where the dent is. - Use scenarios: - Auto body repair at a job site in daylight to locate and address dents on flat panels. - DIY dent work on metal sheets in an outdoor workshop. - Field dent checks in parking lots or remote locations with available sunlight.
