  • Isolated personnel can be located faster using the PRC-112G CSAR radio. Rescue crews will know exactly where you are because the radios’ encrypted GPS updates every second.
  • Secure, two-way messages and LOS voice provide a low risk of being found by the enemy. Even if GPS is jammed or denied, the rescue aircraft will still receive your secure messages. This is known as TAC/TAG.
  • LOS, SATCOM and 406 SARSAT offer multiple ways for you to contact rescue forces. The PRC-112G communicates Line-Of-Sight to our Quickdraw2® Interrogator or Over-The-Horizon to our SATCOM Base Station.
  • Just press "ON" and the PRC-112G can be interrogated. No other buttons need to be pressed. Rescue crews will still be able to extract your location and information as long as the radio is powered on.
  • Coalition forces to the rescue — with 31 countries using the HOOK2® system, you can also be rescued by coalition partners during multi nation missions.
  • Now Available - Rechargeable Batteries
