Гриша от Вертикали - тест на разных верёвках / Промышленный альпинизм

Grisha - Vertical descender/belay device. A quick test on different ropes: the new Kolomna, the old Kolomna, and the Vento Static. I bought it for myself for my "emergency" kit and for my pendulum. ---------------------------------------------------------------------------------- Thank the author for the content: 5536 9139 1938 7924 (Tinkoff) ---------------------------------------------------------------------------------- I'm on VK: https://vk.com/id169151110 Our live chat with subscribers on Telegram: https://t.me/+149yG94_11AzMWJi ----------------------------------------------------------------------------------- #climbers #industrialmountaineering #mountaineering
