Martin is back on his game, sinus' have eased. He hit
107 m (352 feet) constant weight (mask, fins, snorkel, weight belt only) yesterday! He did this with NO PACKING!? Packing is a way that advanced free divers use to compress air in their lungs increasing the volume and bottom time. In Martin's case this means increasing volume of 8 liters to 12 liters (adult males are typically around 5 liters without packing), 30% more air. This is almost akin to one of us grabbing a quick breath and dropping for a shallow, casual free dive. Amazing things are in the works. Good luck Martin!
