Myles and Jake talk all things dive theory and dive medical knowledge with Seth Tufvesson, a commercial diver, hyperbaric chamber operator, and PADI Course Director. He tells us his favorite dive theory facts, how hyperbaric chambers are used for more than just diving, and why he keeps learning new things!

**Reminder** Free Descent is intended only as entertainment, not as a replacement for formal dive training. Always listen to the instructions of your divemasters and instructors, and dive within the limits of your training and experience. Be safe, and have fun out there!
