DEEP PRIMER

WHY TAKE THIS COURSE?

GUE’s Deep Primer (formerly known as Triox Primer) is a course appropriate for recreational single tank divers or double tank divers. It is designed to teach divers the use of triox 30/30 as a GUE standard gas to reduce the effects of increased gas density in recreational divers and to prepare divers to dive to a depth of 100 ft/30 m.

WHO IS IT FOR?

Diving in more challenging conditions—be it deeper, more complex dives on a project or executing a strenuous or complicated task—calls for high mental capacity for all team members.

All divers ambitious for project diving or challenging themselves with dives in demanding conditions should consider using a helium-based breathing mix to make their dives safer and more comfortable. The Deep Primer course is also a great way to prepare for deeper dive training by introducing and practicing ascent protocols.  

WHAT WILL I LEARN?

Course outcomes include, but are not limited to: skill cultivation and refinement, familiarity with the theory and practice of decompression, correct ascent procedures and practice, the use of helium to minimize narcosis, CO2, gas density, and post-dive “nitrogen stress”.
