Postupné zatížení ukáže, jak snadno dojde k vzniku lomu, jeho šíření a jaký je způsob lomu. Kompresní test je dnes v severní Americe i v Evropě nejužívanějším testem stability (Jamieson, 1999). Může jej rychle provést i jedna osoba, pozorování způsobu lomu je náročné.





Výsledek testu je „nestabilní“, pokud dojde k náhlému lomu nejpozději při třetím úderu předloktím. Tak lze odhalit téměř 90 % nestabilních svahů.

Při kompresním testu (CT) je postupně zatěžován sloupec sněhu o rozměrech 30 x 30 cm. Nebezpečné jsou náhlé lomy při malém zatížení.

We have received inquiries about the design and safety of the Pieps DSP Sport and DSP Pro avalanche beacons. These beacons have undergone vigorous testing and exceed all certification standards. They have been sold globally since 2014 and used by countless backcountry travellers ever since. A beacon is a personal safety tool which must be properly used and maintained. Any misuse may compromise its functionality. Please refer to the video on the fourth slide for how to inspect your beacon. Your safety in the backcountry is our top priority. Please reach out to Black Diamond Equipment in North America and Pieps in Europe if you need further information or if you are unsure how to verify the condition of your beacon.

Notable part 4: In the following days I was in disbelief that Nicks transceiver had turned off. The experience left me questioning the Integrity of the Pieps DSPpro. A few days after the incident I sent a email to the guiding community enquiring about similar experiences or issues with this device. I was surprised to see my email flooded with similar accounts, even dating back to 2017. ⚠️The problem being it can switch modes easily without the user’s knowledge⚠️ Due to poor design the button wears out and no longer provides resistance allowing it to slide out of send mode. We suspect the impact from Nick being dragged through the trees switched his to off, burdening us with a full burial with no signal. This only confirmed our lack of confidence in the device, a piece of equipment that is paramount to the safety of backcountry riders. We as a community should not question the reliability of rescue gear and should demand industry standards. Nick has been in conversation with Black Diamond/Pieps with hopes of a product recall of the Pieps DSP pro/sport models and dismantling sales of this product. No recall has been publicly communicated and this device is still for sale online. Our main goal is to get this device off of users in the ski industry, so this doesn’t happen again and again. •If you or someone you know owns one I would suggest contacting BD/Pieps warranty and request a replacement upgrade model. •If you’re in the market for a new transceiver I’d suggest a Mammut barryvox #notsponsored I think it’s a premium product. •Whatever gear you’ve acquired use it properly. Wear it properly. Practice all and every scenarios so when shit hits the fan you can be there for your partners. •Take avalanche training courses. •Hire a guide! Lots will be looking for work this winter. •Find a mentor. •Do a mandatory morning transceiver check. •Acquire a backcountry communication device. The list goes on ... but I hope this has been helpful. Stay tuned as @nickmcnutt & @ianmcintosh will also be sharing more in the coming weeks! Be safe have fun ❄️
