If anybody's interested, we (Stingray Divers) are currently running what I think is the first normoxic trimix course given in the NY/NJ metro area. It's an IANTD course and J.D. Selser of Sartek is the instructor. Prerequisites for the class are listed on Stingray's and IANTD's web sites. Any interested parties please contact me via email or phone. Normally I wouldn't post something like this to the list, but given the rarity of a class like this being held up here, I thought it was warranted.
