Everyone gets Narced, no way around it. Even if you don't "feel" it, its there.
Have them do a simple math test and see what happens at 130 feet.
I was at 126 in 45 degree water, found a really nice port hole. My wife said I cleaned the outside off really well, then started knocking on it and talking through my reg. She asked "Ok?", I said "Ok" we went on with the dive. Got back on the boat, she said "Did you see the anchor? It was next to that port hole." I said, "What Anchor?"
