Quick Answer
PLBs (personal locator beacons) activate satellite rescue. SPOT devices text location continuously. Mirror signaling covers large areas. Fire signals visible from great distance. Ground-to-air markers remain visible after escape. Multiple simultaneous signals increase detection probability.
PLB and Satellite Devices
Personal locator beacons activate rescue satellites. Position transmitted to rescue coordination centers. Rescue initiation rapid—within hours in remote areas. Limited one-time use per deployment. Cost premium ensures reliability. Backup communication improves chances.
Ground-to-Air Markers
Large ground markers visible from aircraft direct rescuers. X configurations indicate emergency. Bright colors contrast with surroundings. Arrows point toward location. Ground markers visible indefinitely. Complementing with audio signals improves detection.
Mirror Signaling Enhancement
Mirror flashing reaches 10+ miles in clear weather. Practiced technique improves signaling effectiveness. Multiple angles maintain signal. Continuous technique requires less effort. Darkness negates mirror signaling. Different times improve overall detection.
Fire Signal Optimization
Green vegetation produces visible smoke. Multiple fires increase visibility. Placement on ridge-tops maximizes detection. Smoke production timing coincides with aircraft activity. Fire maintenance extends capability. Fuel gathering limits other survival activities.
Communication Devices
Satellite messengers send text updates. Coverage extends beyond cell phones. Dual-device backup prevents single failure. Monthly subscription maintains constant coverage. Rescue initiation before critical situation develops. Proactive communication improves outcomes.
