Is it advisable to probe before digging during a rescue?

Rationale for Probing

Probing is a crucial step in avalanche rescue, allowing you to quickly determine the depth and location of the buried person. A probe is a lightweight, collapsible pole used to feel out the terrain and locate any buried person. When probing, use a slow and deliberate motion, inserting the probe into the snow at an angle of about 20-30 degrees. This helps you to avoid pushing snow into the air pocket around the buried person’s head and ensure a more accurate reading.

Techniques for Probing

When probing, start by inserting the probe at a point where you suspect the buried person may be located, such as near the center of the avalanche debris. Use a gentle pushing motion, feeling for any resistance or obstacles, which could indicate the presence of a buried person. As you probe, take note of the depth and any obstacles you encounter, such as rocks or other debris. It’s essential to keep the probe as vertical as possible to get an accurate reading. This technique is often referred to as the " probe-to-probe" method.
