Training & Air Crew Signaling -
Safe, Precise, Visual & Non-Verbal -
Target Marking for Rotary Wing Aircraft

Rotary aircraft crews require laser technology that can be safely used in training environments and in laser safety restricted air spaces and/or live fire exercises. They need a capability that provides for safe, precise, visual, and non-verbal communication between pilots and crew; between crew and ground support; to mark LZ's; for "squirter control"; for signaling & "target talk on"; to point out obstacles, terrain features, or even aircraft rotors to insure obstacle clearance. We are matching mission and training tasks to the appropriate laser capability & power output. Crews require "eye safe" power outputs; portability, ease of use, economic pricing; used hand-held by crews, gunners, and pilots; laser use through closed door windows (rubber hood in development - see gallery).

Instructors, Trainers, EOD Techs
Tactical Teams, SWAT, Hostage Rescue

Precision Beam & Dot Adds Clarity
Eliminate Confusion - Reduce Operational Errors

Use as a training laser for JFO & JTAC target marking; for tactical team coordination - for general training in schools, training centers (NTC & JRTC) and training ranges (when higher powered units are too dangerous to employ)  FDA Certified Class 1 Eye-Safe for any use - military or civilian.  Still 1,000 meter range with Gen 3 night vision optics.
