I thought I post an update for some closure to this thread.
We went to the pool by ourselves several times after certification to work on my wifes kicking technique and it improved greatly. Something finally clicked and now she doesn't have to think too much about it.
We wanted to do some more pool dives, but the dive shop ended up not allowing us to tag along after we had been certified.
They said they only allow students who have complete confined water training, but are not yet OW certified to go to the pool for independent practice. I am more than a little annoyed by this because we really shouldn't have even been certified in the first place.
We talked to another shop that would less us tag along to the pool, but they do all of their confined water training in a 5 ft. deep pool which seems pretty useless. If I remember correctly, many of the skills must be completed in water too deep to stand in, so I have no idea how they get away with using that facility.
We ended up going back to the quarry by ourselves for a couple dives last weekend and actually had fun this time. We kept it simple and mostly just practiced establishing neutral buouancy and swimming around the training platforms (15 and 30 ft). This experience gave us a lot of confidence and we will continue learning to dive, but definitely with a different instructor/dive shop when we feel we are ready for AOW. I think our way forward will be to continue diving, but simply stay well within the bounds of what we feel comfortable doing. Right now that may only be circling training platforms between 15 and 30 ft., but we will eventually progress at our own pace.
While waiting on the surface for an OW class to leave a platform, we saw our first "emergency". A geyser started coming up from the training platform from a free-flow. We assumed that it was part of the training, but then a student pops up hacking up a ton of water followed by an instructor that is beating on the students regulator to try to stop the free flow. The student was towed to shore and looked pretty disoriented, but was apparently OK.
