Last one I bought was from Northeast Scuba Supply, Blue Steel.

Filters work well. Alt, try getting a 50w HALOGEN light and filtering that. There is a boatload of non-visable light pouring out of that. You might even find a UV bulb for a few bucks only.

Ditto!! Count me in (please)!

Vortex?

My DAN expired yesterday. I've been a longtime member, but had a very encouraging conversation at BTS this year with Dive Assure's rep. After looking over the policies, 2 things grab me in particular with DA: 2 or 3 wheeled Vehicle exclusion "Mountaineering" exclusion So If I repel into a...

Update: I completed the classroom and pool sessions with Peter and the Staff Instructors at Scuba New York in Yonkers, then finished the OW in West Palm Beach, FL. Peter, and all of SNY were great and I would highly recommend any/all of them. Got perfect 5's for the in-water portion and...

Reckless endangerment? Criminal Mischief? Failure to obey boating laws? Vandalism? Assault? Pick a couple, make at least one GOOD one stick. Fine enough to let him, or anyone reading about it, never ever muck with a dive flag or the diver under it. Same should go for those special little...

Wireless is for convenience only. If it matters, and I argue it does, one needs a reliable mechanical backup. An O-ring on a port plug or an O-ring on a sensor are all the same to me, but there are no electronics in my SPG... YMMV

LONG "safety stops". SLOWascents. Go diving, get on a plane, go home.

He's getting off WAY too easy....

20.5' to even begin on-gassing beyond immediate assent... A buddy of mine used to dive a cave with average depth of about +270 and run time of +18 hours. He'd fly, almost every week, 4 hours after surfacing and was never bent, year after year. The real issue is after a dive like that is if the...

You can stay indefinitely at 20.5' and still ascend immediately to the surface. 19 hours after a 30' dive, I'd not worry. It's all about coming out clean anyhow. Do slower and longer ascents and dive nitrox if available. Hang at 15' until low on gas, then take 5-10 minutes to surface. Do this...

Is that Hog 32# a singles wing?

So almost ready to assemble my LP50 doubles with a narrow manifold and bands. Wing Candidates: Oxycheq 42# horseshoe Halcyon 40# Evolve Nomad (old style) Dive Rite Venture wing (old style) Total width shall be a tick shy of 13". My guess is the Oxycheq, but I might be selling...

Ok, a standard 3000 psi AL80 nominally holds 77.4 cubic feet of gas. Period.

Helium is a tad different at pressure as there is a compressibility factor. I don't recall the math, and as was alluded to, it's an ideal gas law. In practice it's more a "fudge factor".

There is a partnership going on to some degree. The new Halcyon reg is only cosmetically different from the SP by all accounts. BP but not wings same, spring straps same..... Much overlap....

The Scubapro backplate also works, but that's for hopefully obvious reasons.

When I spoke to the girl in the video whom was being antagonized, she told me she was pretty scared at the time. The whole thing still creeps her out to this day... They sorta laugh about it, but it's a bit of a nervous laugh.

Ha! Egg on my face! My bad all the way! I knew they were looking for a chef on the Kona boat, saw Aggressor and misspoke! They had also been looking for a chef on the Bahamas boat during BTS, so might be that one ...
