I used Mike O’leary, his cell# is 386-961-8075. he is an excellent instructor, he has been around forever,we did our dives in peacock springs, and cow springs. he uses Dive outpost I believe, he is a NSS-CDS instructor. when I get some time to get some more cave dives in, I will use him for both apprentice, and full cave. he is funny, he yells underwater too, quite funny. good luck with whomever you choose. it is excllent training.
