Earlier quoted context omitted.
Past CDL holder here. Fyi, you are then a "professional driver" even in a normal car driving to the grocery. If you get a ticket, many states will instantly double the fine because as a pro, "you know better". Plus there's the medical aspect and other bullshit. Unless you're going to actually use it, dont get it. Learn to drive an 18 speed with air brakes etc, sure. Just dont get the actual cdl.
to add to this, if you dont actually use your SCUBA or first responder or pilot skills on a regular basis, those certs are worthless at best, and dangerous at worst.
Dive shops with more advanced dives ask for total and recent experience as well, and sometimes require you to do a refresher or dive with them once before they take you on the advanced dives (deep, night, high current, overhead obstacles etc). The OW cert is a big contributing factor, but it's not the only data point.
That said most other recreational certs are useless and just a money grab, even including advanced, imo. Shops generally rate OW+30 recent dives higher than OW+AOW, and rightly so.
