He's gone out since then. A bunch of time's while he was in Guam and a couple times with me last year. He's just a little upset as he'd rather not have to pay to be AOW certified now just so he can go off of a boat.
It's not a law, it's a policy. Seems like an easy fix, talk to the boat operator and show the dive log. If they don't want to recognize experience then find another boat.
Experience should be worth something. Who is likely to be more comfortable in the water... a PADI AOW with 15 dives or an OW with a 100?
One of my dive buddies in Japan only had an OW certification... but he had been diving for over 30 years and had over 2000 dives
