What is performed before each mission on a TruDefender?

• A. Confidence test
• B. Battery replacement
• C. System reboot
• D. Calibration check

Answer: (A)

Readiness of the TruDefender is verified with a confidence test before every mission. This quick, built-in check confirms the instrument responds to a known reference and that its sensors, electronics, and signal processing are functioning within specification. It ensures the alarm thresholds and readouts are reliable so you can trust the results in the field. Battery status and a system reboot are routine but don’t by themselves prove detection capability, and a calibration check, while important, is typically done on a scheduled basis rather than as the immediate pre‑mission test. The confidence test directly validates that the instrument can detect targets you’re about to encounter, which is why it’s performed each time.
