Hey guys, trying to put together some numbers for NH with regards to the affect divers have on the lobster fishery. Does anyone know what year the law was passed for Mass divers to hunt lobster? And what year the law went into affect? Also, is anyone aware of any formal studies that have...

Other than the obvious spelling mistakes it was not a trick question at all. My point was simply that most people believe empty = 0psi. But when you are down say at 99 feet empty is typically the point that you can no longer breath off your reg. The two are not the same. When you are down...

I watched a Navy diver forget to set his j valve and do a CESA from 80 feet on a fun dive. He was diving and got seperated from his group and was about 50' from me. He looked fine like he was doing a normal ascent but I noticed the steady stream of "small" bubbles and no inhale. He was calm...

exactly! call him and ask...

I actually worked the numbers and in NH divers would probably take 1600 pounds of lobster a year give or take... The inshore commercial guys take 1,400,000 pounds a year. Even if we took the lobsters right out of their traps--I am not sopporting that in any way--at the end of the year they...

Although it looks like another year and another strike on the NH lobster Bill. Interesting thing though after speaking with fish and game. Did you know hunting lobster was a social issue? I confronted F&G with some real numbers (thanks to mass for keeping good records) and they relented and...

I was not going to reply, having read this thread late but your reply is a contridiction by itself. You first say that you could have a leak in the first stage of your pony and not have the gas there when you need it. You go on to say if you are going to use one to sling it (i agree with this...

The posts here are good. One thing to remember is that SAC rate is typically in terms of psi /min. That will help if you alwyas use the same tank but a more useful number is ft3/min. The previous post did a good job of explaining how to convert between ft3/min and psi/min. Understanding...

The idea is that you will not have time to nicely purge your reg. You are going to inhale instinctivly.

I thought it was 83.2%....

So you are basing your assertion on what you have seen or heard about and not any real statistics. 10 accidents in 5 years may or may not comprise "most" accidents. Although you want to make a point so you say "most". Please PM me the reports they may make for interesting reading.

you are at 120' same thing happens???? It boils down to training...

Not that I advocate this practice BUT comments like this are entirerly unfounded. What statistics do you have to say "thats when most accidents and fatalities occur." If you look at the DAN accident reports you will find, at least with their reporting, that your comment is not true or in...

It seems like you have a reason to do it that goes beyond "I want the card because it is cool". Too many people do it for just that reason not understanding that there is a liability associated with it as well as additional responsibility. If you have a good reason to do it then go for it...

So just so that I understand, you were able to do your DM course without a log?

That is cool and I was not trying to one up you at all it is just that there are a lot of people out there that believe it is propper to ditch and dart if they are OOA. I actually know somone who did it and then had a chamber ride for the effort. The reality is, and there are a lot of...

Dropping your weights should always be a LAST resort. You were trained to do an emergency swimming ascent and for that you need your weights. Once again, dropping your weights should not be the first thing you think of when you are OOA and your buddy is not around. You are absolutly correct...

I hate posting in threads with this many responses but here goes: first: as was brought up in many posts there is really no reason short of catastrophic failure (and even then) to have a total OOA. Next and more importantly, you need to be conditioned for such an event. It is not...

My question is this: Since it sounds like you are very close to neutral at the start of your dive, is there any chance that you are properly weighted at the end of your dive? :06: Proper weighting would mean that you are overweighted at the start of a dive by the swing weight of your tank...
