Dealing With Depth
- Divers carry larger volumes of breathing gas to compensate for the increased gas consumption and decompression stops.
- Rebreathers manage gas much more efficiently than open circuit scuba, but are inherently more complex than open circuit scuba.
- Use of helium-based breathing gases such as trimix reduces nitrogen narcosis and stays below the limits of oxygen toxicity.
- A diving shot, a decompression trapeze or a decompression buoy can help divers return to their surface safety cover at the end of a dive.

Famous quotes containing the words dealing with, dealing and/or depth:
“In my dealing with my child, my Latin and Greek, my accomplishments and my money stead me nothing; but as much soul as I have avails. If I am wilful, he sets his will against mine, one for one, and leaves me, if I please, the degradation of beating him by my superiority of strength. But if I renounce my will, and act for the soul, setting that up as umpire between us two, out of his young eyes looks the same soul; he reveres and loves with me.”
—Ralph Waldo Emerson (1803–1882)
“What we do in our dreams we also do when we are awake: we invent and make up the person we are dealing with—and immediately forget that we have done it.”
—Friedrich Nietzsche (1844–1900)
“People who comprehend a thing in all its depth seldom remain true to it forever. For they have brought its very depth to light: and there is always so much nastiness to see there.”
—Friedrich Nietzsche (1844–1900)
