| Megalodon Sighted...proof that living specimen exists (AP) Reuters April 27, 2007 - 12:32PM MST by Jdicediver - Not a staff writer Earlier today, just off the desolate coast of Alberta, a previously thought extinct species of giant shark (Megalodon Charcharadon) was sighted by an excited local enthusiast and admirer. The entire population of these primitive sharks were thought to have been decimated by the giant squid (genus architeuthis) around the time of the last ice age (12,700 years ago) but new compelling evidence proves otherwise. Contrary to the beliefs of a contingency of scientists known globally as: A. (additional Rebreather(s) you have had experience on or have owned) this ISC derivative species has ruled the Oceans of the globe for millions of years, and will continue to do so for many more. I do have your attention now, haven't I? Well...enough fun on my part. Now...on to the exciting part... Finally paid for, One COPIS Megalodon, training to be initiated 12 May with his eminance Mr. FIGJAM himself... Looking forward to experiencing what all the rave is about... |

| Re: Megalodon Sighted...proof that living specimen exists Well...I now do understand. Definition form Wikipedia.com: A rebreather is a type of breathing equipment that provides a breathing gas containing oxygen and recycles exhaled gas. This recycling reduces the volume of breathing gas used, making a rebreather a lightweight and compact breathing set for long durations in environments where humans cannot safely breathe from the atmosphere. Hmmm...interesting concept, now all I need to do is quit "nosebreathing" to maximize the recycling of that exhaled gas... Wait a minute...so how does that wediveBC guy get 4+ hours on 500PSI worth of O2? OK...it says "Humans"... LOL, gotcha |

I don't think 4 hours + on 500 psi is possible its probably closer to 1.5-2hrsDefinition form Wikipedia.com: A rebreather is a type of breathing equipment that provides a breathing gas containing oxygen and recycles exhaled gas.

| Re: Megalodon Sighted...proof that living specimen exists I don't think 4 hours + on 500 psi is possible its probably closer to 1.5-2hrs That's only approximately 100 liters of O2 (if using 3L tank).So depending on how deep the dive (and the diluent used), you might just used up a portion of that to get to SP at depth. My guess is 100 liters will be good for about 1 hour before the pressure is too low to flow... :) |

| RBW Member | Re: Megalodon Sighted...proof that living specimen exists That's only approximately 100 liters of O2 (if using 3L tank). Yeah that sounds about right. I know I can get close to 6 hours of diving out of a 3l cylinder filled to 180 bar. When I fill it it usually has 20-30 bar left. I'm sure Dave is about the same unless he doesnt breath.So depending on how deep the dive (and the diluent used), you might just used up a portion of that to get to SP at depth.
