I notice they are now downloadable at: CG-45 - Downloads /downloads/Manuals/DACOR/

Was told, and then confirmed that VDH no longer allows downloading old manuals and catalogs, although they can still be viewed. I can only speculate about rationale. Feel free to PM me.

Alert Diver | Snorkels: Pros and Cons

Doctor Pollock has now graciously retracted the erroneous statement. See the Letters column of Alert Diver (Winter 2016).

Whenever you're in water more than a few degrees cooler than your body temperature there is a net flow of heat from you to the water. I've had similar experiences as you, but instead of the hydration explanation, I theorized that staying warmer means less heat energy lost. Less loss of energy...

For many years we planned to retire to the Cayman – English speaking, low taxes, low crime, good medical care, short trip to the US – but then my wife got a job in Hawaiʻi ... Our second choice was Belize.

As with so many things, “it depends”. I’d never take a large open water class over a wall. However, on a couple of occasions I have taken a pair of open water students down a wall to 55 feet on dive three of their training after first assessing them on dives one and two and after discussing it...

Anyone who added the comfort swivel (02-0095-3P or 02-0195-3P) to their Atomic reg should have one lying around. But I checked, and I have the universal fit version (02-0097-3P) instead, so I don't. sorry

To clarify, are you looking for: a Jam Nut - Atomic part number 02-0037-00-B or a bolt or something else?

Brac hotel owners told to clean up site :: Cayman Compass

Unfortunately the THC in this context (as I understand it) is mostly methane.

The short answer is: for non-tech diving you’re probably fine getting it from a firehouse. Especially if the firehouse has the proper valves for filling scuba, and even more so if they have their own scuba team. The major difference between SCUBA grade E and SCBA grade D or L is total...

The OP said and folks here have interpreted that as never working as a DiveMaster, which is not quite the same thing. It's possible Wiltol simply means just what he said - no intention of making it a career. I taught scuba for several years and never considered it a career - it was a sort of...

CO2 is what triggers us to breathe. Off-gassing CO2 better by more complete exhalations (reducing dead air space) invariably reduces gas consumption. Simpler than yoga.

Agree with tursiops, awap et. al. For starters, the link you provide for Dive Gear Express shows 9/16", all the Home Depot ones are 1/4".

Lubricate both O-rings and threads. from: http://www.anchorrubber.com/specialty/parker_o-lube.pdf And some "light" reading here about thread lubricants...

Using Hoover’s book as reference it appears to be a Blackside Hawkfish AKA Paracirrhites forsteri AKA hilu pilikoʻa.

At least I haven't heard the opposite postulated. Although there's surely someone who thinks diving nitrox makes them more tired (oxygen toxicity aside).

There are many variables in actual dives and divers, and fatigue is subjective, so it’s difficult to design a valid study. But there are so many independent anecdotes that it’s hard to dismiss the concept. I’m one who thinks Nitrox helps me – especially on multi-day...
