272 ft. on a breath without fins

Just came across a video that explains why the record attempt was shifted to the shelf of the Blue Hole from the open ocean. It includes some great training footage including Martin electing to stay at 90 m (296 ft.) for 30 seconds as a part of his modified regimen?! I think I stayed for maybe twice that long around that depth on SCUBA a gazillion years ago, narc'd out the wazoo and falling into O2 Toxicity. Amazing performance!
