Advanced signal searching for very large avalanches

The analogy between a landing airplane and the different phases of a transceiver search include numerous points , such as a good balance between search speed and search precision, or the distance of the device to the snow surface.

Important measures for avoiding interference when using transceiver.

The Basic Snow Conveyor Belt, allows for efficent excavation of a buried subject with minimal rescuer training.
The system is optimized for average burial depth. Special cases can be handled more efficiently with the full version of the Snow Conveyor Belt.

Precise fine search technique for very deep burials, such as subjects in terrain traps, narrow creek beds, or crevasses.

The Group Check verifies that the transceivers of all group members are turned on and functioning properly. This systematic approach provides a quantitative range check on a daily basis. The tests are done within a defined test distance with minimum requirements for transmit field strength and receiver sensitivity. The single group check only checks the SEND function of the participants and the SEARCH function of the group leader. The double group check verifies SEARCH and SEND of the participants and the group leader.

An ideal ratio between search speed and search precision leads to the best search performance: as fast as possible and as precise as necessary.

Understanding  the problems interference can cause, distinguishing a "real signal" from a "false positive" and searching in heavily disturbed areas.

 Pravilno tumačenje oznake udaljenosti i izrada mentalne mape scenarija spašavanja pomoću višestrukih podataka o zatrpavanju koje primi primopredajnik ključno je za uspjeh. Pravilno razumijevanje situacije omogućava donošenje ispravnih odluka koje se tiču najboljih strategija pretraživanja i spašavanja.

Efficient use of resources when multiple rescuers are present while finalizing the last two search phases. Thanks to clear commands and physical separation of work spaces, the team is saving time and increasing the chances of survival.

Achieving the “Greatest Good for the Greatest Number” when you are short of rescue resources.  Buried subjects in shallow and average burial depth require less resources to be saved and have higher chances of survival. It is advised to prioritize those subjects before excavating deep burials.  Deep burials absorb a lot of the limited resources and the likelihood of survival is lower.

How to achieve “Greatest Good for the Greatest Number” when you are short of rescue resources. Taking into account burial depth, terrain features, trees, and presence of vital data, when defining the sequence of actions, will lead to a higher overall success rate. Buried subjects with a higher chance of survival, who require fewer resources, will be prioritized.

Personal rescue equipment for traveling in avalanche terrain.

By determining the position of the buried subject with multiple probe hits of a probing spiral, it is possible to optimize the starting point and alignment of the Snow Conveyor Belt.  This reduces potential for mechanical injuries and head access times.

The overview is showing the four search phases of a transceiver search in avalanche rescue. This sequence of actions provides an efficient and systematic approach to search for a buried subject.

Procedures for solving multiple burial scenarios with an avalanche transceiver. Taking advantage of the user friendly and efficient marking features is the first choice.  Based on reliable criteria it is useful to determine, when it is time to switch to an alternative search strategy: The Micro Search Strips or the Three Circle Method.
