I object to the ad because what it is really saying is, "So simple even a dumb chick (and we know that she's dumb because she's clearly had breast augmentation surgery) can use it." Now put Sylvia Earle or Kathy Sullivan there with a rebreather and I'll pay attention.
One a more personal level I find three problems with the ad and the thread:
"Chicks" (except one "chickdiver") are not people I respect or turn to for advice about anything that my life my depend on. Maybe I'm old school, chicks no, women yes.
I do not really trust people who, barring horrendous disfigurements, are so uncomfortable in their own skin that they have to pay someone to take a knife to them and, despite significant health risks, alter the way they look. I would not knowingly seek advice from someone cursed with that level of vanity about anything that my life my depend on.
Bikinis are not practical dive wear, people who mix them with rebreathers (at least after Labor Day) as so déclasse that I'd never ask such a one a question concerning anything that my life my depend on.
