My wife and I are avid divers, we have been dive buddies for 30 years. I am AOW but she is just OW. We have talked about getting her AOW but just can't seem to see any reason to spend the money or time. She has 500 plus dives, excellent buoyancy, doesn't get lost when we dive in Bonaire , constantly dives to 80- 100 feet and follows all safe diving practices. We don't feel.any need to get further badges just to say we have them. We think that experience is much better than any badge we may have. Only once did her cert level, or lack of, be questioned (Florida key when we wanted to dive Speigal) but once the master watched us it was not a problem. How many of you did not pursue advanced certifications? Bill ( i have AOW but was 20 years young when i got it....i am now 58)
