Scuba Diving Gear

Used Scuba Gear

how long is it posible to stay under water using scuba gear?

whats the longest someone has stayed under water for and whats the longest time one can stay under water for? 3 days ??

Your question can not be easily answered, since the deeper you go, the less time your air will last.
Consider it this way...every time you double your depth, you halve the amount of time the air will last. It's not accurate, but it's a rough estimate.

Diving at 30 feet (approx 10m), for someone whom is fit and not exerting themselves, they can spend somewhere around an hour exploring on one tank before they start running critically low.

As for staying underwater, I believe a research crew in the Carribean has the record there. They stayed in a habitat for several months.

Good Luck!

Scuba Gear in the Bathtub $25.19 Edna Goldberg often finds herself exasperated by her husband, Henry, and his unconventional behavior. Henry enjoys his antics thoroughly and loves to annoy his proper, strong-willed wife. Thus begins a marital struggle of miscommunication, circumstance, and sometimes embarrassing situations. Like any married couple, Henry and Edna have their nuances. Henry's slow driving habits and his tendency to roll his hankie up in the car window to dry are enough to make Edna want to shove him out the door. Henry must contend with his wife's snoring and hogging up the bed, but through it all they still love each other, and in spite of everything, reminisce about their wedding and how their life together all got started. Though they encounter many minor mishaps, they wed at last and live happily ever after-for the most part.
