Have the right light at the right time. The Recon employs Gerber's D.I.A.L. (Diode Illumination Adjustable Lens) technology - a feature that shines four different colors from one super-bright white LED: white for general use; green for map reading; blue for fluid identification; and red to presere night vision. Powered by two AA batteries, the Recon weights 2.6 ounces and includes a clip for hands-free use.
