On your 150-foot dive, did you have a dive buddy? And if so, what would have been your ascent strategy if at 150 feet your buddy would've signaled OOA?
Sometimes we hang a bottle from the boat in case, but we always use buddies at those depths. OOA procedures are similar as for shallower depths, go to your buddy, signal, and ascend together. We always have ample gas left over, so any deco acquired (if any, usually only a minute or two) are done as directed. The only time I went through this scenario (OOA from deep) everything went as planned. As mentioned previously in another post, they are usually not square profiles so as to maximize bottom time, however we have dives to 120' that are squarish that we do on 80's regularly.
