I don’t ride it to "0" in the ocean, only on the rock jetty. And I try to avoid babysitting on a dive. A Master Scuba Diver shouldn’t be paired with the guy who just finished OW cert. last week. I know sometimes it’s unavoidable, but teaching is what the AOW and Rescue course are for. Not my job on a charter.
I shouldn’t have to "tag along" bored to death babysitting the newbie. I paid the same price for the experience that he did. I should be able to spend my dive enjoying the dive, not looking over my shoulder to see if the newbie grabbed a lionfish or got sucked into a porthole on the wreck by the surge because he didn’t know any better.
