D1™ is a passive laser warning receiver. It detects and coarsely locates laser emissions from other hunters’ laser devices and rangefinders. The D1™ is primarily a safety tool to aid in the prevention of shooting and laser eye damage accidents for downrange hunters. D1™ will alert its wearer of laser emissions through selectable audible, visual, and tactile feedback.

Many hunting incidents occur every year in US in various venues. We hope that this device can provide safety and minimize such incidents.
