What angle should probes be utilized at during UXO operations?

Using probes at a 30-degree angle during UXO operations is considered effective because this angle allows for targeted and efficient detection of buried ordnance. Probing at this angle enhances the ability to generate a more accurate assessment of the soil conditions and increases the likelihood of effectively retrieving items that may be located just beneath the surface.

Approaching at 30 degrees provides a balance between depth and surface area coverage, allowing the probe to intersect the potential UXO more readily while still maintaining sufficient structural integrity of the probe. This technique also helps in minimizing disturbances to the surrounding area, thereby preserving the evidence and maintaining a safe working environment.

Other angles may not be as effective. For instance, probing at a steeper angle, like 90 degrees, may only address items that are directly beneath the probe, potentially overlooking items at varying depths or slightly displaced. On the other hand, a shallower angle like 0 degrees might not penetrate the necessary depth to reach buried ordnance effectively. Overall, the 30-degree angle aligns with the best practices in UXO operations to ensure a more thorough and efficient investigation.
