500meter depth gauge or computer computer - does it exist?

[realcs]

:14:in our quest for the depths and longer bottom time.
is there a gauge or computer thats 500meter depth rating? dose it exsist?:coffee:
if there is what brand is it?:popcorn:
if its a computer what algorithym dose it suport?:D

[DA Aquamaster]

Sp used to make a 500' depth gauge.

The new Uwatec bottom timer I think goes deeper than the old one - 400' maybe?

[SteveAD]

the uwatec galileo is rated to 330.5 meters-1084 feet

[Gombessa]

Scubapro's new bottom timer goes to 330meters (about 1100ft). At 500m, would you start seeing those creepy transparent, bioluminescent fish with huge teeth?

Thats pretty deep. I hope you are AOW certified.

[JahJahwarrior]

I think the real question is how many tanks do you need in order to get in a good dive at 500 metres AND decompress?


Makes me wonder, what kind of stops would be required for a dive to 500metres? Also, that's, what, 55 atmospheres? Wikipedia says the average lung capacity is 6 liters, lets assume you only exchange half of that per breath, that means at depth every breath uses up about 6 cubic feet of air, right? So you'd get 14 breaths off of an 80.....


^did I do that math correctly?

Google: 77.4 cubic feet / ((500 meters / 33 feet + 1) * 3 liters) = 14.4070012

Can you imagine your SPG dropping by 200 psi every time you inhale? I think I'd have to go with surface-supplied. :D

Do you really want a third of a mile of umbilical line? If I ever considered a dive like this it would be rebreather time.

[ClayJar]

Do you really want a third of a mile of umbilical line? If I ever considered a dive like this it would be rebreather time.Absolutely, I'd want myself and the bell to be on an umbilical, and I'd want sandwiches waiting for me inside so I can grab a bite as I begin the long deco.

[Dark Eternal]

The amount of gas is not the problem - it is what gas and what the pressure affects are. You would need such hypoxic levels of oxygen to stay under a reasonable P02, not to mention the narcotic effects of your mix gases, helium included at that depth.

Plus, the pressure at that depth would probably throw you in to some kind of deadly neurological spasms due to HPNS.

[SteveAD]

Sandwiches? For a deco from 1500 feet I think I'd want a bed!

[fppf]

Sat Rats have been heard to go to that depth.
Of course it takes 7 or more days to deco.

[mempilot]

At 1600 fsw, you would be habitat supported with a either a RB or an umbilical or both. The depth guage wouldn't be needed, since you'd be diving from a habitat (known depth) while saturated. The Megalodon has been sport dived to @ 1000fsw, but other more commercial units have been used much much deeper. Remember though, with sport diving you are starting and ending at the surface. You would have one hell of a time with decompression logistics from that depth. The guys doing work at those more extreme depths are in saturation and do their decompression later on the way up in the habitat and then on the surface in the habitat/recompression chamber. Many days of it. :)

Do you have any reference to this? I thought the rebreather record was 270m and I am not finding anything otherwise.

[mempilot]

Shy of 1000 fsw. I wasn't quoting an exact figure. Cederic Verdier on his Meg might hold that number you are speaking of. Others have gone deeper and died.

[buddhasummer]

Thats pretty deep. I hope you are AOW certified.

;)i have already finished my dive mastership and im doing more advanced training and would like my progerssion in diving to be directed at my goal to break passcal bernabe's world record set at 330metters hence the need for a 500m depth gauge or computer that has a good algorithym.

[Thalassamania]

My old ScubaPro Helium Depth Gauge goes to 500 feet.

[texdiveguy]

...No, at least not through your LDS or an internet supplier.

Where do people come up with this stuff.... :rofl3:

[mempilot]

Ok, this thread went from funny to scary. Good luck on that 'goal'. Eveyone's got to have em, but don't you think that training, diving, and experience should be a little higher on the priority list than buying a depth gauge????? The fact that you are asking here on SB is the first sign that you are already misguided in your path to your goal. Sorry if this sounds harsh.

[SteveAD]

Agree 1000% Asking about what algorithm a computer uses implies that you would be letting the computer manage the deco. Before planningon breaking any records a person should be very well versed in the chosen field. A computers algorithm is based on a theory that should be tested in the real world before the computer is released. In a record attempt, by definition, no one has done it before, therefore the algorithm is not tested to that extreme.

If you want to set a record, first become an expert on decompression theory, so that you can devise your own deco schedule. Then, if what you have learned hasn't scared the carp out of you, dive your own plan.

[realcs]

this is why i seek knowledge, and on the boards and all advices i shall take into account.
its healthy to have fear but dont let it get the better of you.
oh... i was also hopping deep divers would come in on the discution and help me out find a deco plan that i can work to my needs.

You are either trolling, kidding, or very naive. :no

[realcs]

well the best of deco's is what im looking for but im not going to use it just now... heavens sake!
theres a lot of training that id need to go through about 2 years more plus half a dozen more certs. to clear and then maybe then i might give it a try. still id would want to hear from the population of scubaboarders on the deco plan they use..... and whats the norm on deco's today.
"would you mind not going thermal nuclear"

[mempilot]

How about you go through the training, ask your instructors along the way, come back and tell us how your training went, and then maybe you will get a better response here.

I don't think you are going to find anyone willing to talk to you about any of this until you are certified to practice it. How will they know you are certified you ask? It will be quite a bit more obvious than it is now.

I don't believe Cedric or anyone else has been close to 1000 ft (yet). I believe Dave Shaw still holds the sport RB depth record at 890ffw and it wasn't on a meg.

If your goal is to break Pascal's record, finding a depth gauge is the least of your worries. And I don't think you'll be running your ascent following a computer either...

Good luck... how long are you giving yourself to work up to your record breaking dive and how will you be funding it?

Maybe you could buddy up with Papa_Bear on this dive?

Bad advice! if this kid really is naive and not a troll, he might just listen to papa and surely end up dead.

for me training first plus scuba boards advices how can i lose...:D

[BringTheDeep]

What nitrogen charts did Pascal use cause if im recalling correctly wasnt it something like 360 meters.... this is just my humble opinion but there is much more to see a little higher up...and everytime talks of record breakind depths there seems to be a rise in body counts...but what the hell if we never pushed the limits we'd still be in the shallow end at the YMCA

:popcorn:learn to be an expert...... hmmmmmm...... an expert should at least have a good number of principles tryed and practiced in his feild of endevour diving. even when i get the N.A.U.I.cert's i can only say im a good N.A.U.I. member and not the expert since i know only one teaching.
now with the help of the scubaboard guru's i hope that one day i may be considered in the intermidiate category.:crafty:

[mow2000]

It's gutsy of you to ask a question like this on this board. As you have found out you will be labeled a dangerous heretic and quite possibly will be disallowed from diving ever again on this planet.

Years ago i worked with a company that operated and built deepwater ROVs - 0 to 20,000 ft. We had a variety of sensors. You might find some pretty decent, affordable and reliable equipment related to that industry.

Good luck. Go for it. More power to you.

[mempilot]

You are right. I misread the depth in his article. 663. Damn, I need to get my eyes checked! :D

plus scuba boards advices how can i lose...:D

Ahhhh. And the project's achilles heal is identified. :D

[bjpell]

:rofl3::rofl3::rofl3::rofl3:
I was thinking the same thing!!! that was great wasn't it.:D

[realcs]

thanks guys your the best...
2 of my gurus have just drove in and il be jioning there clases in manila after that to sunny tubataha for the start of the diving season.
oh,,, in keeping with the traditions of N.A.U.I. "plan your dive and dive your plan" im going to study, workhard, get more certs. in 2 years time do the dive...... if ive gained enough of all thats needed.............
"water tricles everywhere so dose knowledge" thanks!!!!!!!

Why do I perceive Rod Serling all over this thread?

[ianr33]

To answer the original question (Novel concept :D )

Dont know of anything rated to 500m but the Liquivision X1 will display depth to 400m.

Unfortunately going deeper than 350m will void the warranty. (Thats why I dont have one yet ;) )
