Oh, yeah. I almost forgot to mention all of the divers I know today who supposedly got certified in Aruba, or Cozumel, or Bonaire, or Curacau.....and their certification documents never made it to the issuing agency, and therefore they had to do the class again. Listen to Jon above. He is right about the sites they will take you to for your cert dives. 25’ sandy bottom boring. Good luck!
