New Tech-?

I ran across a Military diver who stated that they are now diving surface supported mixed blood gases via wrist mounted digital moduals. Meaning that the diver's mix is controled by a surface attendent who inputs the data for the correct gas mixtures. This person said they are regularly diving at depths in excess of 750'-! I, for one cannot envision this type of diving technology. Do you think this is possible-? I don't know if I would trust someone else mixing my gases while I was deep underwater-!

Surface supplied (commercial) is restricted by OSHA and USCG to 300 fsw and up, after 300 you have to go into Saturation.
Usually your longest hose is 600 feet, if diving to over 700 feet you would need at least 1000 foot hose, if you were changing mixes at depth the diver would have to free flow his hat for a long time to flush 1000 foot of hose, you would have to have thousands of cubic feet of gas onboard to do something like this.
It really doesn’t make senesce to do something like this; Sat is the way it is done.

In surface supplied you don’t carry any gages and you are 100% totally dependent on the guy setting at the gas rack.

You will be surprised at how much and how many military divers there are out there. Most of them have no clue but since they are in the military it sounds good.

The military does do some awesome and innovating stuff out there but commercial divers do about the same. It is always fun to paly with a diver that says they were a military diver. Expecially when they were a SEAL or Force Recon. I know how much training they get and it in no way makes them a better diver then you or I. Now a Master Diver is differant.

Hahah--OK. Well I have a DD-214 but not a MOS. MOS is for enlisted only.
I had an ODC, do you know what that is? :?:

Yeah I too know a LOT of SEALS who don't know where Coronado is :!: And a few "Navy Divers" who do not whatt SurDO2 is. Lots of 'em out there.

I thought you were stating that real military divers knew nothing about diving.

Since I was just a lowly 5345 and a 5343 I would love to see how you play with divers...

Dang!! Now you've done it Slim. You done poked the old Hornet's nest of Military Veterans. It might be time for us to pile on for a good old fashioned Blanket Party. Which material would you prefer? Wool or the classic Cotton shelter half? Nah. I understood what you meant.
I agree Jim. There are quite a few wannabe heros out there.
I myself was a diver for Delta Force, TF-160, SAS, SBS, GSG-9, and the Mossad. Unfortunately I washed out of S.E.A.L. training due to a terrible sand rash and a painful hangnail. Doh!!!
Now if anybody asks, My Dog ate my DD-214. :-D

I met a navy diver who didn't know what an M-value was or the relation to the Navy Dive Tables but when I explained it he got excited and pointed me towards the tender diving medical officer I think he remembered recently hearing something similar when he had had to sit through some stupid weekly training on. ;-)

What's 'SurDO2'? Surface duration O2? Never mind - I better not ask.

Surface deco on O2. In a recompression chamber.

0311 is the only MOS that does any work, all others are just there to support us.

Not entirely true.... I started off as a 5811, ended up working exclusively with 0311s in the field... and not in a support role either. Which makes sense since 5811 is an off branch of the 0311s...

Could you guys tell us what all these numbers mean? 0311, 5811 etc.

MOS's

Per the MOS Manual:

"The Marine Corps Occupational System uses a four-digit number code constructed on the concept that occupations with similar skill and knowledge requirements are grouped in functional areas, known as occupational fields (OccFlds), and jobs, known as Military Occupational specialties (MOSs); "

5811 - Military Policeman
0311 - Basic Rifleman

Every Marine from a cook to a General Officer has an MOS.

Okay, Jim, as we both know, since we both dive the same dives and talk to the same experts, the Navy no longer does thier own deep water research. They use the private sector for research. My advanced diving says more about what is to come then my Marine Corp MOS (1161). If someone wants to know what's coming in tech diving, ask the experts in the private sector, not the military. Ask the divers that are plowing the frontiers. Sheck Exley did what he did because he was a math teacher and a math wiz. Look to the folks with that ability that are diving to see what the future of tech diving holds, both those with and those without degrees...

OKay Bruce, that is certainly an interesting perspective. A quick Google search on the Navy Experimental Diving Unit (NEDU)yielded the following information from the NEDU website. http://www.supsalv.org/nedu/

During the 1980s and 1990s, NEDU did a large amount of saturation diving to evaluate diving equipment, examine deep saturation diver thermal protection problems, test active and passive diver thermal protection, validate decompression algorithms,test various carbon dioxide
absorbents and scrubber systems, develop Treatment Table 7, and conduct mission-specific training for various special projects.

In 2001 and 2002,NEDU divers made essential contributions
to the ex-USS MONITOR salvage project. The mission was a three-year, joint National Oceanographic and Atmospheric Administration and U.S.
Navy expedition to recover artifacts from the historic site 16 miles
south-southeast of Cape Hatteras Lighthouse off the North Carolina Coast.
In 2002, NEDU completed the final openwater demonstration dives for certification of the MK 16 Mod 1 UBA to 300 feet of seawater (fsw) in the Gulf of Mexico. The 300 foot open-water certification dives completed a fouryear product improvement process that included: extending the
working limit from 200 to 300 fsw, developing 1.3 atmosphere constant partial pressure of oxygen decompression tables for nitrogen (N2O2) and helium (HeO2) diving, providing an HeO2 repetitive dive capability
for dives shallower than 200 fsw, testing an emergency breathing system (EBS) with integral communications, adding an integral buoyancy compensation device, and adopting an improved full face mask.

Over the past 75 years, NEDU has evolved from a small team of Navy divers to a diverse workforce of over 150 people including military divers from the Fleet, EOD, SEABEE, and SEAL diving communities; PhD scientists and engineers; diving medical officers, physiologists, and research psychologists; and many talented technicians and support personnel. NEDU’s mission has evolved from Gunner Stillson’s original assignment to evaluate diving equipment and procedures to a much broader mandate that includes a wide range of undersea and hyperbaric
biomedical research and development. As NEDU looks towards the immediate future, we foresee research focused on procedures
for contaminated water diving, advances in diver thermal protection, furthering our understanding of oxygen toxicity and decompression illnesses, and preserving a Navy capability for saturation diving.

It reads, at least to me that perhaps the Navy is doing some research.
