You want something that's attached to the bottom, not the surface, because the surface moves.
But you live in California... surely you are aware the "bottom" can move here!

I know my ascent was not too fast and disregard the warning... I always follow these rules: never ascend faster than the bubbles...
Published rate can vary between faster ascent of 30 ft./minute to a more conservative PADI recommendation of 60 ft./min. If you are using the bubble trick you should be looking at the smallest bubble, not the largest bubble.
At what rate do your bubbles ascend to the surface?
" I was watching the computer ".......So this how some 'new divers' do an ascent??..ie watching their computer???...........Practice staying below your smallest bubble---if you want/need a guide/gauge---& it's colorless.................
Read that link again! It does NOT say bubble ascend at 60 ft/min. They may go faster. [Also, the smallest one don't go up at all. So if you follow the bubble of a certain size, maybe you are OK. Which size? Depends...] So the linked article says don't follow your bubbles.I've heard from Scubaboard and some other places that bubbles ascend at about 60 ft/minute: Scuba Diving Bubble Mechanics

If you still have air in your BCD at 15 ft with about 500 PSI in the tank, you're overweighted, so get rid of a couple pounds of weight on the next dive.
