No, the OW cert is valid to 130 ft. The recommendation is to dive to 60 ft, unless you have furter training/experience. I concur with the rest of your post. Good job, OP.A diver with a PADI Open Water cert is supposed to be limited to a max depth of 60 feet. So the fact that you were going 25 feet beyond that depth and that he had just a few logged dives should have been a red flags for both you AND your buddy! Thankfully you were level headed and handled the situation allowing the dive to end without becoming a major incident.

It is not true that you cannot breath below 150 lb tank pressure. Easy to prove. Turn your valve off and breathe on your reg.
Almost all major certifying agencies use the depths that you outlined as recommended limits. Everybody is free to make their own decisions. That said, you generally need to hire somebody to get you there and they'll start asking questions.I don't agree with this. I was OW certified in December and they told us, and I also read this during the KR portion, that the limit for OW divers is 60' or the max depth at which you were trained. AOW is when you are certified to dive to the rec limit of 130'.
Even if you were right, the AOW depth would be 100, not 130.I don't agree with this.

In fact, the actual OW certification is to 130. It is only recommended to stay at 60 with OW and 100 with AOW.
You are referring to the maximum "training" depth, 60 ft for OW and 100 ft for AOW. The recommendation is you not dive beyond your training depth. I am referring to the "certification" depth; the OW card is good to 130 ft.
I'm sure you're correct about the policy, but it sure sends mixed messages, doesn't it? It's easy to understand why a new diver might be confused about what is an appropriate depth. Adding to the confusion is the fact that 60ft in warm clear water is a lot different than 60ft in poor visibility, currents, cold temps, entanglement hazards, etc.....
It's not an easy thing determining a "safe" maximum depth, and that's probably why PADI doesn't do a good job of providing a clear simple policy. Personally I don't know if there's a possible improvement or even how important it is.
here are no enforcement bodies patroling, writing tickets or pulling cards for violations. It's up to the diver, the DM, the operator and common sense to keep divers alive and safe.
OK, let me do a simple math that you can prove me wrong. Let's say I'm in 60' deep, ~ 30 psig or 2 barg or 3 bar absolute (bara) ambient pressure. The SPG is showing 150 psig or 10 barg or 13 bara pressure. I have 30" long hose of each low pressure hoses for the 2nd stage primary regulator + octopus + BCD inflator (total 90" long) with 1/4" (6.5mm) ID hoses, which sum of the volume comes up to 76mL x 13 bara hose pressure / 3 bara ambient pressure = 328 mL ambient air volume. My lung has about 6000mL volume. 328/6000 x 100% = 5% of my lung volume. I call that OOA.
