digital signal processing dsp rapid signal recognition and long digital range with direction and distance display as well as 457 khz and w-link signal pattern recognition for quick and reliable recording of multiple buried subjects in a list multiple buried subjects intelligent search audio-supported fine searching in a cross bracketing is simplified by using arrows these clearly show on the display the direction to walk in based on the distance and signal information in relation to the avalanche transceiver the device helps users by means of information regarding when to change search direction and the optimum transition from fine searching in a cross bracketing to probing pinpointing photo marc van swoll the starting point for guided fine searching dynamically adapts to the depth of the avalanche and the device guides the user based on the remaining distance to the buried subject using one or more processes of fine searching in a cross bracketing pattern recognition is used to record buried subjects in a list and record them as found by means of a marking function this means that multiple buried subjects can be located without having to use special search methods analog mode analog mode is for resolving challenging search problems using micro search strips the 3-circle method and circular fine searching the width of the search strip can be increased to 80 m in analog mode and the receiver sensitivity can be adjusted manually earphones can be particularly useful for analog searching rescue-send this mode is used by all rescuers who are involved in a rescue but not personally carrying out a transceiver search in this mode the 457 khz signal is temporarily switched off to avoid interfering with the search in the event of burial by a secondary avalanche the motion sensor detects what are now only very slight movements by the rescuer and automatically switches the transmitter back on after four minutes allowing the buried rescuer to be located using a transceiver vital data a highly sensitive motion sensor measures even the most subtle motions of the body e.g those caused by heart and lung activity each movement is interpreted as a sign of life and displayed by means of w-link as an increased chance of survival message in the form of a heart icon in the list of buried subjects on the searching device energy source the devices in the barryvox® family can be operated using different battery types alkaline lithium in comparison with alkaline batteries lithium batteries offer longer operating times in low temperatures and do not cause any damage due to leakage • element barryvox® alkaline • pulse barryvox® alkaline lithium
