Digital Technology What is the difference between digital and non-digital (analog) beacons and how does that make the Tracker DTS better?
The Tracker has two major advantages over analog avalanche beacons: digital processing and a dual-receiving antenna. Digital processing removes the searcher from the process of having to interpret the victim’s signal. Rather than the searcher walking in a “grid” or “tangent” search pattern, stopping regularly to determine the signal’s “fade points” and turn down the sensitivity control, the Tracker’s microprocessor does all that internally. It receives the signal, filters out extraneous noise, adjusts the sensitivity, determines the direction, measures the distance, and provides information to the user in clear visual displays. This is much less time-consuming and training-intensive than grid or tangent searching. The Tracker is the first beacon with a dual-receiving antenna. This enables the Tracker to be extremely precise in determining the direction of the victim’s signal. As a result, the user has a very precise indication of which direction to travel to stay on the electromagnetic
