Question 1 of 27070

Which of the following would best be used for visual detection of a distressed vessel?

🔍 Key Concepts

• EPIRB (Emergency Position-Indicating Radio Beacon) primary purpose and how it alerts rescuers • Difference between radio beacons (RF signals) and visual signals (lights, flares, etc.) • Purpose of a 9‑GHz SART (Search and Rescue Transponder) in a SAR operation

💭 Think About

• Which of these devices is specifically designed to help you SEE the casualty with your eyes, rather than just help rescuers LOCATE it by radio/radar? • Think about which frequencies (9 GHz, 121.5 MHz, 406 MHz) are associated with radio or radar signals, and which device commonly includes a bright light visible at night. • In an actual search and rescue, which option would help an overflying aircraft or nearby vessel visually confirm the exact position of the distressed vessel in darkness?

✅ Before You Answer

• Identify which options are primarily radio beacons for detection by satellites, aircraft, or ships, not the human eye. • Confirm which device type commonly includes a high‑intensity strobe light for visual marking of position, especially at night. • Make sure you distinguish between radar detection (SART) and visual detection (light seen by eye).
