Great advice. I would add, you needn't take a class as such, find a good instructor and pay him to evaluate your skills and discuss, and work on what is needed. A class is good if you need a particular skill, but becoming a better diver is a more nebulous question and may not be found in a...

Not anymore. The first dive of the day there is extra air, extra buoyancy, in all your gear that won't leave until you are at depth. So if you have weighted neutral at 15', empty BC, with 500# in your tank on your last dive, you will be positively buoyant on your first dive next time out...

For those that haven't heard about Sherwood. From 1930 was one of the formost US companies in design and manufacture of high pressure gas valves, regulators and associated equipment. They are still in business. In the 1950s, as the fledgling scuba industry developed, they turned to Sherwood to...

Not my experience, although I can see how it could, when unpressurized.

That's what happened to mine, except it did not ruin the reg, only the dry bleed system. I had the the dry bleed swapped out, with the last dry bleed the shop could find, and the reg rebuilt. I now use that reg on my pony. Not bad for a demo reg I bought cheap from a shop in 1980.

Yeah, worded poorly, the IP should remain about the same, but would seem lower since it is not compensated for depth. With an IP of 140# at a depth of 130' the iP would be about 65# lower than an unbalanced reg wants at that depth. I don't know if one could breathe off the reg, but once panic...

It should be resolved by now, as the link is from 1998. I am confused, as this was not how my Sherwood acted when the dry bleed system malfunctioned and I continued to dive it. To be accurate, there are two different systems, and I believe the one mentioned is newer than mine, however both...

If the night watch was there at the time, as a roving watch he could be somewhere else long enough for the fire to become deadly. All trash is kept onboard so it would have only moved the fire, placing it with more fuel.

It's been so long I couldn't tell you what brand, or diopter, but I think it was the same as my readers. As for application for stick ons, insure everything is clean and wet, place the lens where you want it and press it down on the glass forcing out as much water as practical. Because I dove...

5.32.005 B and 5.32.060 A, exclude any motorized craft of any type, regardless of description. Sounds like a scooter could easily be included. I would, of course, ignore it and play stupid, although some say it is not an act, when caught, apologize and retreat. In my experience there will be...

I don't know what 120's you are diving, but the Faber MP 120's I have are great for me in cold water diving wet with a single tank.

Amen to that.

Rent a bigger tank and see how it works for you, it will give you more air, and you can see if there is a down side for you.

For those three, go to PigBoats.com and look up the boat for pictures of the salvage, that Ric could find. For books: On the Bottom: The Raising of the U.S. Navy Submarine S-51 Blow All Ballast!, but it's easier to find The Terrible Hours, or Back From The Deep. If searching the web, check for...

I wouldn't have bothered, not because of the overhead, or the U turn, but because I did not have experience with the divers accompanying me. Being last or first in line wouldn't be a problem, but I doubt you were given a choice.

Has nothing to do with the tank, if we had your 300 bar tanks, it would still have to have a burst disc.

That's why I picked up my AOW 29 years after OW, hell, that's why I pickerd up my OW card after 17 years of diving, sooner or later I knew I would across a knucklehead that wouldn’t understand that I was a diver when I talked to them, and I wouldn't get a fill. Get your card, it will save you...

Kinda, a lot of folks I know that go snorkeling never get the top of the snorkel wet, and believe that's how it is meant to be done. That's why I try to make a distinction between the two. Like Cthippo said, I think there is a lot of overlap in the recreational world. And terms change meaning...

It may be possible, but would not be prudent. It's kind of a trick question, since any US scuba tank made for 3500#, and over, is required to use a DIN valve. As a recreational diver you probably won't run into a 3500' service pressure tank anyway, unless you buy one used. I've used my...

There is Freediving, and then there is freediving. The first is focused on records and the other on spending some time underwater enjoying whatever brings you there. If you are there for a record, for God's sake, get some training. If there for fun, do not hyperventilate, and surface when you...
