The black glass lens, IP68-rated waterproofing, and 1.5m impact resistance mean it survives the environments where Goldbacks actually circulate. At 5.2 inches long and 0.67 oz, it fits in a pocket. Two output modes: High (850mW): up to 1.5 hours continuous, 15 to 20 meter beam range Low (165mW): up to 8 hours continuous, 5 to 10 meter beam range Runs on one AAA battery (not included). Compatible with all 2025 and later Goldback notes across every state series. If you're buying, selling, or accepting Goldbacks at the register, this is the verification tool designed for the job.
