Physical fitness supports safer diving, but when and how you exercise around dives matters.

DAN recently hosted the Instructor Qualification Course (IQC) and Instructor Trainer Qualification Course (IQTC), co-taught with the Powered by DAN partner training agencies: SSI, NAUI, IANTD, and SEI.

Through Powered by DAN, dive training agencies integrate DAN’s full curriculum for basic life support, CPR, oxygen administration, and first aid directly into their programs. The goal is simple but critical: capable first aid providers at every dive site.

DAN’s curriculum is the most comprehensive in the dive industry, covering more skills than any other courses for lay providers.

Most divers know that failing to equalize can cause pain or injury but fewer realize that unequal equalization of the two ears can lead to disorientation and vertigo underwater.

This article explores alternobaric vertigo, what causes it, and how divers can reduce their risk. Read more here: dan.org/alert-diver/article/understanding-alternobaric-vertigo.

Part of being a great diver is knowing when you may need a refresher course! 🤿

For your first dive after a period of inactivity:
✔ Consider diving with a Divemaster or Instructor

As water activities increase, so does the need for highly specialized rescue and recovery support. IUCRR is rebuilding its operational strength and welcoming motivated, qualified divers who want to make a real impact.

Thanks to everyone who joined us! These presentations will be available on DAN’s YouTube channel in the coming weeks.
