Subject: RE: Helmets for cave diving. What's the deal?
Date: Mon, 14 Jan 2002 06:35:03 -0500
We have sidemount situations in WKPP diving, mostly to check new things out
or remote locations, or to map very tight passage, but we see no need to do
it like strokes.

There are SAR divers who use our methods, and there are several police
forces who use our methods. Check with Mark Lonsdale of LA County Sheriffs
and see how he does it.

Some military also use our methods, and two of my people just got back from
working with Marine Corps . JJ and I did a presentation for Special Forces,
and those guys did some more work with JJ.

You guys can piss and moan all you want. If any of you can come up with
anything that works better than DIR or makes any sense at all, I'll kiss
your ass in Macy's window. I have had that bet out here for years and have
yet to see one of you come up with anything but bullshit.

In addition to rec, tech, and commercial diving there is a 4th variation
(and some will say there are more ) on being underwater called Public
Safety Diving. PSD itself has many incarnations, including swiftwater
rescue and recovery, but the main stem of this activity is recovery of
bodies and evidence in waters less than 60ft with visibility approaching or
at zero(blackwater),  with a high potential for encountering unknown
obstructions underwater including masses of barbed wire and abandoned
vehicles,  often in very cold and contaminated water.

Painting with very broad strokes, the diving is performed by single divers
on SCUBA using back mounted single tanks and mounted, not slung pony
bottles, tethered and controlled by tenders, with two backup divers on the
surface, one ready to go.

No buddies, no doubles, no DPVs, no reels, no cannister lights,no 7 ft
hoses, no wings,  pockets instead of d-rings, etc. Not DIR, unless by this
term you refer only to a method of thinking.

Reading the account of the form of cave diving performed by the Brits, in
very tight circumstances in zero viz it seems that what they are doing is a
lot more like PSD  than 2 mile penetrations at 60 fathoms,(where DIR has
more than proven itself to be the method par excellence - no argument
there).

How would DIR configure the PSD diver?  Is there a DIR form of PSD diving?
Who practices it and how are they confgured? And how would the DIR diver
configure himself in the sumps the Brit divers "stroke" through?

This is true. But can it be said does it apply to DIR itself especially
after those at the top of the DIR hierarchy have decided how it is to be
done?
