Black Diamond Recalls PIEPS DSP Avalanche Transceivers Due to Risk of Loss of Emergency Communications; One Death Reported


PIEPS DSP Pro, DSP Pro Ice, and DSP Sport Avalanche Transceivers


The transceiver can switch modes unexpectedly when not locked or installed in the harness. When this occurs, it will prevent the transceiver from transmitting a signal and can make it difficult to locate a skier in an avalanche, which can result in severe bodily harm or death.
