This episode is brought to you by our brilliant sponsor, XDEEP and the patrons of Speaking Sidemount. Huge thanks to both for their support that makes this podcast possible.  In this episode, I catch up for the third time with Thorsten Waelde or Toddy as he is known. I first met Toddy in Episode 24 when we did a deep dive into Toddy Style Sidemount. We caught up again in episode 44 to talk about his Utopia Exploration project in Sardinia only a few months after I had returned from my trip there. I've since been following Toddy's exploits with interest and when I saw the stunning work he was doing on the Bel Torrente exploration via a video on Toddy's YouTube channel (See link below), it was time to catch up and hear more. The amazing part of this project is that it is a multi-sump or siphon project where the cave under exploration has dry sections connected by flooded passages. The penetration length requires the exploration team to live underground for several days, staying at base camps in the dry sections as they progress further into the cave. This creates massive complications to the project, especially the logistics of moving the equipment required and the physical and mental application required is immense. In this episode, Toddy gives us an overview of the Bel Torrente project. He talks of the team he has assembled, the skills required before we get into the logistics of this project, the equipment, and the evolution of their procedures as they encountered new challenges and requirements at each section. We talk cave geology and the risk and danger of an accident deep in the cave before Toddy explains how he uses Seacraft Dive Propulsion vehicles and the new lightweight Seacraft GO that is easier to carry across the dry sections. We finish discussing the Cave Camps that Toddy runs at Protec Sardinia, where qualified cave divers can experience aspects of these projects by diving into a cave and spending a night at a base camp. The Cave Camps include workshops on how to use dry tubes to take equipment into the cave and a heap of time exploring the beautiful dry sections of the caves in Sardinia. I am super excited to check these out. Enjoy, cheers!! Steve Thanks to: Our Sponsor - XDEEP Thorsten "Toddy" Waelde - Protec Sardinia YouTube Video - Follow the Conger: Exploring the Bel Torrente Cave
