Avalanche transceivers are small electronic devices worn close to the body. When travelling, everyone’s transceiver sends out a radio signal. In the event of an avalanche, those not buried switch their transceiver to search mode and follow the signal toward a buried person.
Three antennae digital transceiver with a visual display and audio display set the standard for ease of use, speed and accuracy. Features and functions may also include a marking function for locating multiple burials, or transmission of “vital data” to support triage.
Single antenna (analog) transceivers are considered obsolete. Need convincing? Three antennae digital transceivers generally won’t find single antenna transceivers as well as digital units. That means if two people are buried close together, the one with the digital transceiver is likely to be isolated first. Signal overlap can also be a significantly bigger issue with old transceivers in a multi-burial scenario. If you are still hiding your SOS under your jacket it’s time for an upgrade.
Got that? This is important stuff.
