Hi Jay
Thanks for your input ,being a commercial diver
using Poseidon and Kirby Morgan has become a religion to me over the
years , not because they the smoothest ,but to me have proven there
reliability .The cyklon 300 and 5000 when there lp valve is full open delivers
20 bar this should be enough pressure to over come the pressure at 100meters,
and also ok for my bail out supply .The deepest I have dived is only
65meters, so diving to 100meters is something I am looking forward to
.
I will speak to some of old tech divers
,thanks for bringing that to my attention.
All the best
Glen SA

Glen,
There
is only one regulator I know of that will function maybe to this depth.
Poseidon made a special regulator for regulator testing and it has been used
for the very deep tech dives such as Sheck Exley made in South Africa and
others on the WW I German battleships off of Virginia. The air in a
cylinder that passes through a regulator at 60 bar is very ?thick? (much
higher density) and does not like to go through a typical regulator plus you
have to worry more about icing of the regulator. I have experienced
issues with the seating material and parts of the piston in a regulator when
running them at pressures higher than they were intended for. You might
consider using the Poseidon regulator (if it is still available, Poseidon in
Sweden has went through some management changes since I last dealt with them)
or adapt a regulator that is manufactured for these pressures to a scuba tank
yoke.

I
like you pics you would do well in Africa.I am waiting for my Elliptical end
for my hatch to be delivered in +- 2 weeks,but I have already finished making
all the viewports I was hoping to release the hold down device at say 3meters
below the surface on diving and pre resurfacing as part of
a compulsory check list I plan on using a slotted hinge system
which allows the hatch seal to mate flush with the hatch ring.Its a good idea
to go lighter with the hatch its the last place one needs allot of unnecessary
weight but as you can see I plan to use this weight to my
advantage.
James
seems to be considering saddle mbt's(nemo style) I have already decided
on going this way to minimize deck space and freedom of manipulator
operation. I was thinking of fitting bilge pumps to get max floatation on
surface the other thing is should I make the saddle mbt"s with fore and
aft compartments to prevent airlocks.I am also trying to modify a scuba
1st stage regulator to deliver an higher pressure on its lp outlet to a
max of 60bar to reduce my pressure on my air system because its easier and
cheaper to get high quality fittings in lower
pressures.
Any
thoughts will be appreatiated.
