While only very experienced divers, with professional Dive Masters supervising the dives – including blending the gases – many professional divers, and very experienced and serious amateurs can safely pursue depths up to 400 ft. Two of the primary deep mixtures include: Hydreliox, a blend of carefully metered oxygen, helium and hydrogen; and, Trimix (the more commonly found blend), a mixture of oxygen, helium and nitrogen. I would imagine that the experienced divers involved in putting this video together were using one of these mixtures -- NOT for general recreational divers!David Forwardhttps://www.blogger.com/profile/15838876992410760867noreply@blogger.comtag:blogger.com,1999:blog-365858055267871677.post-30503765396722116632013-11-16T17:00:03.401-05:002013-11-16T17:00:03.401-05:00That IS a deep dive for a surface dive!That IS a deep dive for a surface dive!Old NFOhttps://www.blogger.com/profile/16404197287935017147noreply@blogger.com
