- Cedric Verdier: Cedric Verdier is a Meg instructor who has tested the machine and himself to astounding depths. Cedric, a Technical Diving Instructor Trainer for 16 years, pushed the limits of the SRA Keow Cave to 201m/663ft on May 17, 2006. For this 6 hour-long dive, he used a standard ISC Megalodon Closed-Circuit rebreather with an axial scrubber and no major modification except oil-filled handsets and battery compartments. The Megalodon CCR performed flawlessly at these extreme depths. To learn more about Cedric and the Yamashiro project you can visit his site at http://www.cedricverdier.com/.
