Which MX908 mode is used to increase sensitivity for trace detection?

• A. Hazard mode
• B. Hunter mode
• C. Calibration mode
• D. Sleep mode

Answer: (B)

Detecting trace amounts relies on making the detector respond to very small signals. Hunter mode is the setting that boosts sensitivity and tunes the instrument to pick up these faint signals. It typically raises the gain and adjusts the signal processing to emphasize low-level detections, improving the chance of detecting traces without ignoring them. In contrast, Hazard mode is meant for high-concentration or dangerous items and may limit sensitivity to prevent false alarms, Calibration mode resets or tunes the device to a known baseline for accuracy, and Sleep mode reduces power by turning down most functions, making it unsuitable for active trace detection. So Hunter mode is the best choice when the goal is to detect trace amounts.
