I did my PADI DiveMaster class online , and also Dive theory . Both ran about $225each . Dive Theory online test counts as part 2 of the required actual tests. I still have to have my LDS proctor the part 1 test, then go through all the rest of the actual hands on training. If I go forward to instructor, I’ll probably go IDEA. verses being locked into PADI and PADI membership/dues/fee’s .
