HEL-STARA(R) Lead Jumper Light was designed to mark the lead jumper during parachute operations. Equipped with Ultrabright IRs that emit in a distinctly unique flash pattern of Morse Code "D", HEL-STARA(R) Lead Jumper Light unmistakably marks the designated leader. HEL-STARA(R) Lead Jumper Light provides four functions in two selectable operating modes in visible and IR. This new device offers the HAHO/HALO community new flexibility on marking personnel. The tan & black body helps distinguish it from other HEL-STARs. HEL-STARA(R) Lead Jumper Light Advantages Safety - The unique battery access design provides a curved profile on all sides, minimizing snag hazard. VelcroA(R) attachment provides emergency peel-away from helmet to reduce potential for snag-related injury. Versatility - Up to four user-defined functions are available in a range of visible colors and IR signals, either flashing, coded or steady. Visibility - Omni-directional. Intensities can be scaled up or down for special requirements. Exceeds FAA 3-statute mile requirements. Simple, Secure Operation - Switches are designed for positive operation by a gloved-hand, in the blind, with the helmet donned. Mode selection switch design options provide operational flexibility or strong security between overt and covert operating modes. Operating Extremes - Shock and vibration resistant, dustproof and open sea waterproof to 130 fsw (laboratory 300+ feet). Status Confirmation - Switch design provides visual and tactile confirmation of ON/OFF and operating status with no guesswork; visual confirmation prevents inadvertent battery discharge in the IR operating mode. Easy Battery Replacement - The single CR123 cell can be replaced in the field, quickly, without special tools Functions Mode A GR(S) GR(S) + WH (FL Morse Code "D"/Bright Max) Mode B 890nm IR (FL/Dim) 890nm IR (Steady) + 850nm IR (FL Morse Code "D"/Bright Max)
