At what distance should probes be utilized during mine detection?

Utilizing probes during mine detection is critical for safely identifying and retrieving potential unexploded ordnance. The appropriate distance for probe usage helps ensure that the operator can accurately detect the presence of mines without accidentally triggering them or exposing themselves to undue risk.

The choice identifying 2 inches or 5 cm is ideal because it strikes a balance between minimizing the risk of detonation and maximizing the sensitivity of detection efforts. At this distance, the probing technique allows operators to find mines while maintaining a safe margin that is compliant with established safety protocols in UXO operations. The spacing is designed to ensure that when probing, the operator can effectively assess the area without excessive force or disturbance that could inadvertently trigger an explosive device.

In contrast, options that suggest either less or greater distances do not provide the same level of safety or efficiency. A distance that is too short may not allow for adequate assessment of the area around the mine, while a distance that is too long may reduce the effectiveness of the probe in accurately identifying the mine's location. Thus, the specified distance of 2 inches or 5 cm is both practical and aligns with best practices in mine detection operations.
