Summary: The Pieps TX600 is a miniature transmitter for dogs and other equipment (like that pricey sled) that might be buried by an avalanche, but which should never be rescued before humans.
The TX600 transmits 1 kHz below the frequency used by avalanche transceivers (i.e., at 456 kHz), so it will not be received when searching for an avalanche transceiver.
The Pieps Pro/BD Guide, the original (yellow) Pieps DSP (with the version 8.2 update), the Pieps DSP Pro, and the (recalled) Pieps Vector can be toggled into a special mode where they will then search for this off-frequency signal.
