Ortovox carbon probe, 240cm. This is an older model, so the set-up system is a bit different. Please check the photos. The tensioning part uses aluminum, so it's heavier, but the durability is better than plastic. There are no issues with the joint adhesion. The pipe diameter is 12mm, and the weight is 300g for the main body and 10g for the case. I bought this as a spare, but I've never used it. I never took it to the mountains, so it's completely unused. I set it up once to check it when I bought it, and then put it away.
