Title
Precision Diving - The Great Lakes Premier SCUBA Dive Training
Description
Excerpted from the website:
- I began diving in 2001 and quickly fell in love with the sport. In 2004, I became an instructor. Quickly afterwards, I came to believe there was a better approach to diving than what was currently being taught. I was fortunate to have been trained in skill mastery and team diving concepts by some of the greatest instructors in the world. I found this was the way I wanted to dive and teach my classes.
