ABSTRACT A device for detecting persons buried by avalanches which consists of a hollow rod connected to a suction pump and detector for breath of persons buried. The rod is closed at its lower end by a probe head whose outer configuration is greater than that of the rod. A sleeve is carried by the rod adjacent the probe head and its outer configuration is smaller than that of the probe head, the sleeve consisting of porous metal and radial bores in the rod on the inner side of the sleeve connecting to the hollow interior of the rod. Pore ducts in the porous metal thereby connect the environmental atmosphere adjacent the probe head with the detector and do not become blocked by snow into which the rod is thrust.
