Several buddies of mine and I also took cavern thru full cave (in addition to AN, Deco, and Trimix) through Jeff Bauer. He was fair, worked with us, and provided us the opportunity to work on many different skills and drills Also, he had an uncanny ability to remember all of our mistakes during our checkout dives. All of the above have helped make us better cave divers and made sure we could handle various issues while cave diving. Jeff lives in Tallahassee so it would be easy for him to do a day of dives at JB and alternate with Peacock, Ginnie, or Little River. The millpond also has some other caves in addition to JB.
One of my buddies took a gas mixing course with Jeff Loflin and was impressed with him. I have met Jeff several times at Edd's and found him to be good guy.
I dove with Tracy Grubbs during an NACD skills seminar and based on that dive and feedback, he seems to be a good instructor.
Ditto what others have said about Rich Courtney. I have not dove with him but have met him several times at his shop, on a dive trip, and at the NACD annual social - super guy!
Do you know if that's the same Jeff Loflin that is a PADI course director...?? (Tampa) If so, I did my IDC with him 15 years ago in Key Largo..Glad he is still diving...
