Thumbs Down: DiveNavís Fake Nitrox Class

from the March, 2012 issue of Undercurrent   Subscribe Now

Nitrox certification is a snap. I can't imagine than anyone has ever failed a course. But now comes along a group called DiveNav. Its email advertising says, "You probably heard about nitrox during your OW course, but are a bit concerned that a nitrox class may be too difficult for you. We are here to help!"

Its "Introduction to Nitrox" online class teaches "everything you need to know about nitrox ... physical and physiological aspects of diving nitrox ... the important limits of nitrox ... how to determine the best gas mix ... the use of nitrox tables and how to calculate oxygen exposure limits ... how to analyze the content of a nitrox tank . . . the class includes both quizzes and a final test. All of this for just $4.99 . . . Complete the class, then visit your dive store, easily pass their agency-provided nitrox course, get a nitrox certification card and then .....become a Nitrox Diver!"

Take this course and exam for pretend, then do it all over again for real?
