To make sure everyone is aware: the Pieps DSP Beacons/Transceivers are consistently switching modes while stowed properly. If you haven't heard the story specifically,
Nick McNutt's ski partners think his beacon switched off during the avalanche, which resulted in the full burial. Nick's beacon had been checked at the trailhead.
Since putting stories out on social media, everyone is hearing more and more fail stories of DSP Sport and Pro avalanche transceivers. A lot of folks just thought "oh shit, I guess mine is being funky, must be my fault." I've personally heard from a half-dozen or so friends who have seen the same issue.
IF YOU HAVE A DSP PRO OR SPORT BEACON: keep that shit in a drawer.
Also, consider emailing Black Diamond and Pieps requesting an exchange for a transceiver that will work under stress.
Ideally, Black Diamond, Pieps, and/or their parent company Clarus Corp will issue a mandatory recall notice on all DSP Sport or Pro models and immediately discontinue sales. This is a beacon that has a huge potential to fail during the times you need it most. This is a model that carries potentially criminal negligence due to the manufacturing errors.
However, they haven't done this yet. So, it might be helpful for their office folks to know how unsafe their product is.
If you need help finding the email addresses of Clarus Corporation employees, feel free to DM me.
TLDR: Don't use that shit, your life depends on it. Don't let your friends, their lives depend on it. Go raise hell until we have a safe product.
