Didn’t even see a pool during my entire OW all of it was in ocean. Yeah the first two were in confined water but it was choppy and we got the experience of diving off a boat and getting back on, stuff you miss in a pool and less challenging than in fresh water so I feel that this was a plus over my daughter’s experience who I believe did her check dives at Blue Grotto.
I’m not an instructor, but have been along on 4 OW certifications. Two were for my two daughters, and two were for me.
First, my daughters’ classes as they were fairly typical. Both had several pool sessions. Both actually had extra. Oldest daughter completed her pool sessions in private lessons, then weather cancelled the dives. So, they added her to the next classes roster. So she did the pool sessions again. Checkout dives were at Blue Grotto and Devil’s Den. Devil’s Den was not part of the original plan, but the Gulf was not cooperating that week.
Youngest daughter was similar, all though the cause of her rescheduling was due to her nervousness. She did the pool sessions twice, then did checkouts at DD.
Both are very comfortable on boats, and both have been diving off my boat since, so I’m not really concerned about that not being part of their checkouts.
Now for mine. I have 2 OW certs, and neither was what I would call typical.
First OW cert was done without any pool sessions. We were shown how to setup the gear in the shop, and worked through the academics. OW dives were planned for two days. First day was a shore dive in the sand. Max depth was maybe 8’. I’m fairly certain it was just one dive that day, but possibly two. We just did the skills and that’s it. The next weekend was planned for Rainbow River, again very shallow. I couldn’t make that due to schedule, and the instructor did not require me to make it up. I got my card after just that one day in the water.
The second OW was quite different. Course was over 6 weeks. We met 3 times each week. 1 was for academics, and the other 2 (3 hours each) were for doing a bit of planning and spending the rest of the time in the pool. Pool was at least 15’ deep, so much deeper than my first dives. After that, we did several boat dives in the Keys. Standards are different today, my deepest dive on that trip was around 80’.
