:beerchug: What is thought to be the world’s oldest drinkable champagne found in wreckage between Sweden, Finland. LOUISE NORDSTROM Associated Press Writer STOCKHOLM — Now that’s some vintage bubbly. Divers have discovered what is thought to be the world’s oldest drinkable champagne...

I recently went through the same thing. I dive mostly cold with some warm water. I went for the 40 lb wing. It doesn't have much more drag than the 30 lb, so I really didn't see a downside. I dive wet in a 7mm farmer john and a steel tank. So the SS BP, STA, steel tank, and regs are about...

I did AOW in Utila, were planned on doing 6 dives prior to the trip. We paid about $75 more than we would have for the 6 dives (total $240??), they gave us the book, and we picked dives so they would satisfy the AOW course. We did the education part on the surface intervals, and took the book...

Thanks TSandM. I've ordered a used wetsuit so I don't have to worry as much about additional weight and have a source of redundant buoyancy. I know a SMB and lift bag can also be redundant buoyancy sources, so long as there is enough time to deploy (in a potentially stressful situation)...

I find it particularly amusing that he offers no support for standard length hoses, other than "that's the way most manufacturers ship them, so there must be a reason". I also am amused by the "what happens if the primary fails, the octo is too short to buddy breathe." If the primary was...

Duh :bonk:, because he needs 40 lbs. of lift.

And if you can flip some rocks without kicking up silt, and happen to find a crayfish, the bass will eat it out of your hand. :D Pretty cool to watch.

Thanks Math major. :eyebrow: Interesting reading, and teaches some of us new guys a lot who actually have an interest in understanding the math and physics of diving.

The tables assume you spent your entire time at max depth (and using air?). So the tables assume you went to 130 feet for 60 minutes. Theoretically you could calculate your time spent at each depth with no surface interval to understand accumulated nitrogen loading at the various levels. That...

The wetsuit will lose between half and two thirds of it's buoyancy at depth, depending on the depth. So the wing needs to lift that 16-22 lbs of buoyancy loss, plus up to 7 lbs. of gas consumed in the cylinder. That is 22-29 lbs. It also needs to float the rig on the surface without me in...

Thanks for your reply a22shady. It looks like you dive with a similar amount of ballast with your drysuit as I do in my 7mm super duper buoyant farmer wetsuit, and a similar setup/tank. So let's say you wore your weight on a belt instead of the trim pockets. If you ditched it you'd be...

My thinking was that I was wayyy overweighted. But Ilve had to use that much in the past and the wing lift calculator confirms it. It's the 32 lb farmer john that is the problem. Run the calcs and tell me what I'm doing wrong? I'm using a total of about 30 lbs of ballast for a 32 lb wetsuit...

Thanks for your reply. After dumping the 10 lbs. weight belt I'd still be swimming 20 to the surface (6 lb BP, 6 lb STA, and up to 10 lb tank). What I'm really getting at is should I go with an AL80 tank instead of the HP100, but the 9 lbs I'd cut from my back would need to go on the belt...

So to keep a long story short, I'm a wetsuit diver and I typically dive coldwater in the Atlantic off NJ and a at local quarry. I've recently made the switch to a BP/W to get some lead off my belt and onto my back, previously trim was an issue with a heavy wetsuit. With a BC I was carrying...

I took the time today to do a buoyancy check on my Neosport Farmer John, 7mm XL John with 7mm XXL Jacket. I folded the suit nicely with my weight belt wrapped around it. It took about 30-32 lbs to sink. I did my best to get all of the air out of it, but maybe I didn't. Does anyone think it's...

Still looking.

I'm looking for a used/great condition Halcyon Eclipse 30. PM me if you have one for sale.

I'm sure there are people that dive without an analog backup, and some will tell you it's fine. I believe in the philosophy of redundancy, and dive with a wrist computer and analog console backup. My console is a Zeagle Co-Pilot slimline, it has the pressure and depth gauge on the front and...

wrong forum.

I've been diving for about a year and still sometimes struggle with the same scenario you describe, especially when adding a new/different piece of gear. Buoyancy checks on the surface will get you close, but you need to dive your configuration and adjust your weight based on the results you...
