Abstract: The width of the coarse search strip that is applied when scanning an avalanche is a major factor influencing the time to locate buried victims. Wider search strips help in reducing this time. If the width is chosen too large, there is some risk of not detecting a buried person. Various methods have been proposed and used for the determination of the optimum width of the coarse search strip. The results obtained by these methods are widely varying because of their dependency on the ability of the testing persons. Also, some methods make assumptions about density functions. These assumptions are not very solid. All of these methods require a substantial number of experiments to obtain useful data. A new method is proposed which, while reducing the testing effort considerably, removes as much dependency from the testing person's ability as possible. The method can also be applied to multiple antenna beacons. The results provided are at least as accurate and reliable as the results obtained by earlier methods.
