So the problem is your trim then, floating head down? You could try adjusting your tank so it sits lower in the BC and/or try some ankle weights in place of an equal amount of belt weight. That might get you floating a little more horizontal. Or if you mean you are floating face-up then you...

Jeanne Bendick, How Much and How Many, The Story of Weights And Measures., (New York: McGraw-Hill Book Company, Inc. ©1947.) Second Printing. p19 Of course, if your personal library is either bereft of such valuable reference books or packed away in storage with your regulators awaiting your...

An inch was originally the width of a man's thumb. Of course, since the Villiage Blacksmith always felt cheated when he bought a 6" roll of twine, it was later officially defined as the length of "3 barleycorns, dry and round, placed end to end lengthwise".

First of all, I should preface this by saying I'm an old Canadian. So I've grown up with the Imperial system, the US system and the metric system and I use each almost interchangably. Metric is easier for math, no question. But there are some instances where the Imperial system is far easier...

I don't know what the specific situation in Nova Scotia, but here in Ontario the Ministry of Labour inspectors are supposedly actively engaged in seeking out recreational divers that perform services for any sort of renumeration. If you take money, they want to see full compliance with...

My computer has an automatic backlight (red). There's a light sensor that turns it on if it's dark and submerged.

Will you be able to get your metric tanks filled in Florida? I know they can't be filled in Canada without a TC or DOT rating.

"Well, I might hit into a water hazard and then I need this stuff to play through..." :rofl:

And how would one go about doing that, exactly? I tried to PM you and it was not allowed.

Dymo?

Seems to me the local LDS had them for about 1/2 that price. A quick google comes up with a number of on-line sources at under US$80: http://shop.store.yahoo.com/scubagear/025055.html http://www.scuba.com/shop/product.asp_category_615 http://www.strategosstore.com/product.asp?3=1342...

Well, I think I said the risk was "no greater", so I'm not sure where the quarrel lies, but no matter... You are almost certainly correct -- on any summer weekend when the citiots come out to play. During the week in the off season, about 1 in 7 residents have float planes. Not counting...

I saw the ocean once -- clear like drinking water, but it tasted funny. Heck, I bet you could look up through it and see if a plane was landing. You are right: it was big, probably almost as big as one of the Great Lakes. Certainly far bigger than my little lake here. :fork: True. Timing is...

I was thinking of that. If it's big enough to be seen from the air, is it still classified as a flag or is it bordering on a sail? :rofl: (I'm not a pilot, but apparently flags are hard to spot from up there. I'm told that's why wind socks are 3 dimensional.)

This question might seem a bit odd but I'm sitting here looking out the window and I noticed my neighbour landing. Right were I was diving the other day. I can hear approaching boats from some distance but how close is a float plane likely to be at the point when it can be heard underwater?

I was attempting to put into words my perception of the prevalent attitude. You are absolutely correct: I am not aware of any agency that has actually said "any buddy is better than no buddy". But at the same time, the agencies are giving people cards certifying, in part, that they have been...

Just curious: Why left? Is this a matter of convention (to keep everyone on the same page) or is there a specific reason it should not be on the right side?

Are you by any chance thinking of "composite" cylinders? Usually a thin aluminium shell wrapped with kevlar or fiberglass, they have a lifespan of 15 years and must be tested every 3 years (in Canada anyway).

I have no knowledge of this incident or what might have caused him to bolt and spit out his reg. But aside from the obvious possibility of equipment malfunction, I have observed that it is not uncommon for a person experienceing a heart attack to fight the oxygen mask -- claiming it was...

Rationalization, or reaction? The "buddy team only" adherents cry loud and long that any buddy is better than no buddy and that, by extension, a diver is safer if there is another diver in the water at the same time. The author draws a distinction between true mutual support and a "false buddy...
