Are newer beacons significantly better than older models?

Advances in Signal Processing

Newer beacons typically use advanced signal processing techniques such as dual-antenna technology, which allows for more accurate triangulation and faster search times. This can be seen in beacons like the Pieps DSP Pro, which can search up to 50% faster than older models. Additionally, some newer beacons, such as the Ortovox S1+, use a “double-antenna” system to improve signal accuracy and reduce false alarms.

Increased Sensor Resolution

Newer beacons often have higher resolution sensors, which enable more precise detection of signals. For example, the Mammut Barryvox uses a high-resolution sensor to detect signals at a distance of up to 70 meters, allowing for faster and more accurate searches. This increased sensitivity also reduces the likelihood of false alarms, which can be a major issue in high-noise environments such as an avalanche burial.

Improved Display and Functionality

Newer beacons also often feature improved displays and user interfaces, making it easier for users to navigate and interpret the data. The Ortovox S1+, for example, features a large, high-contrast display that makes it easy to see the signal strength and direction. Additionally, some newer beacons offer features such as a “follow-me” function, which allows the user to mark their own location and make it easier for other rescuers to find them in an avalanche burial situation.
