Some of the replies on here are absolutely bonkers. People should not be advocating that it is okay for just a "little deco" dive for the average, not decompression trained recreational diver. There is no such thing as "lite deco." 10 minutes of deco is NOT SAFE if you are not trained for decompression. Neither is 5 minutes, etc. Going into decompression essentially creates an imaginary hard overhead for the diver. Would it be okay to recommend the average recreational diver without cave training do just a "lite cave" dive. Only 10 minutes in an overhead. No big deal?
So much can go wrong doing decompression even with a trained diver, not to mention an untrained diver who has no clue what they do not know. It's not about decompressing on air or not. Are you sure you have enough air for your decompression? What if you go deeper or stay longer than planned? Do you have enough air for that? What if you lose gas or free flow? Does your buddy have enough air for you to deco on? Are you going to be able to maintain your buoyancy during deco if something happens like loss of gas or free flow? What about when you lose your mask and can't read your gauge to conduct deco properly? Do you have all the redundant gear you need? You're now in a hard overhead that if you ascend above you are seriously risking your life.
There's no such thing as "lite deco" just like there's no such thing as "lite cave" diving. If you're untrained for it, stay away from it. If you're interested in it, go do the training. Telling people it's "probably okay" to do "just 10 minutes" of deco is irresponsible and is going to get someone hurt.
