Quick Answer
When using a probe in avalanche recovery, carefully insert it into the snow at a 45-degree angle, about 2-3 feet apart, and work methodically to locate the victim. This technique helps prevent further burial and reduces the risk of secondary avalanches. The probe is typically inserted to a depth of 3-4 times the victim's predicted burial depth.
Pre-Probing Preparation
Before inserting the probe, assess the situation and gather information about the victim’s last known location, the terrain, and any potential hazards. This includes checking for any signs of a secondary slide or nearby unstable snow. Ensure you have a clear path for probing and a plan for potential rescue scenarios.
Probing Technique
Insert the probe at a 45-degree angle, using a gentle and controlled motion to minimize further snow displacement. Probe at intervals of 2-3 feet, depending on the victim’s predicted burial depth, which can be estimated using a snow profile or the victim’s height. Continue probing until you reach a depth where you feel resistance or encounter the victim’s body. If you encounter a large obstacle, such as a tree or rock, probe around it carefully to avoid causing further damage.
Probe Insertion Depth
Insert the probe to a depth of 3-4 times the victim’s predicted burial depth to maximize the chances of locating the victim. For example, if the victim is estimated to be buried 6 feet deep, insert the probe to a depth of 18-24 feet. This also helps to prevent over-probing, which can cause further snow displacement and make the rescue more challenging.
