    You guys ever see this photo ?

    Years ago,we had a semi-regilar client/friend that dove (dived? dave? had diven?) with our shop back in the late 90's. He was a pretty serious photographer, and after the afternoon boat trip one day, he and the other divers came back to the shop raving about the dive trip, and some photos he...

    Antique bottle hunting in cozumel

    Years ago, I had a bottle hunting phase, and would sometimes hop on board our afternoon boat, and have them drop me in the water in front of the plaza Las glorious (IIRC). I'd then swim north with the current, zig zagging left and right scouring the bottom, and (hopefully) exit the water real...

    Crotch strap for BP/W......

    I'm wondering specifically about strap thickness, what most people prefer,and why. It's been decades since I sold my dive rite rig,and cant recall what I used at the time, but I suspect it was a 2in width. Now I'm leaning towards the thinnest 1in width, and I'm wondering if there are any reasons...

    Where to find good, cheap single-gauge boot?

    Reviews, prices, quality,shipping,etc are all over the map, (yet still not lot of usable options out there that I could find), so I figured it couldn't hurt to run it by the matrix. Any points in the right direction are much appreciated. BTW, I'm needing it for the common italian-made...

    Question about DIN converters......

    This is probably a stupid question, that I should've already known, but...... Are regs that come from the factory as being DIN, able to have the DIN unit removed, and be fully converted to a yoke reg? I'm not talking about the common DIN-to-yoke adapter, the yoke that threads onto the DIN...

    Questions about wing sizing (how much lift for specific environment,gear, etc.)?

    I checked that wing-lift-calculator thread, but I guess the link is old, because it sent me off into deep space. Anyway, I'm wondering how much wing (in pounds of lift) I'd need for diving in fresh water (cenotes), in a 7mil suit, and toting 3 big steel tanks (like hp120's) ? I used to dive the...

    What's the latest on the NACD ?

    I've just recently found out what a train wreck the NACD has become, but not sure on the details, or what their current status actually is. Most of what I'm able to find is older, and vaguely references things, without providing much detail on what's happened ( apparently resulting in a mass...

    What's the lowdown on stainless, braided HP hoses ?

    Apologies if this is the wrong sub-forum, it seemed about as close as I could get. I'm surfing around the websites of a couple tech operations and noticed these braided steel high-pressure hoses, from Dive Rite, and was curious.

    remote exhaust, or a plain elbow ?

    Just wondering what the consensus is on BC's/wings that offer the option of a plain elbow, or a ("pull-to-dump") remote exhaust ? Love 'em ? Hate 'em? Unnecessary junk? Potential weak link? My interest is primarily in a wing system, and for tech/cave applications. (And to head-off the most...

    Cost, obsolescence, and how much 'better' can lights get ?

    Going by my convoluted thread title, you probably gathered that I have a mixed bag of questions. I just read a comment referring to the advancements dive lights have made just since 2010, and then i think back to the big, badass (and heavy) Dive Right canister light I had back in the mid 90's...

    Y'all expect the lionfish population to surge during the diving shutdown ?

    As I understand, the lionfish are often (and legally) killed on sight in the marine park, and I was wondering if it's expected that the shutdown might noticeably affect their numbers.

    Help w/ budget XXL suit for nephew.......

    I've been largely out of the scene for a decade+, so I'm not really up on who's-who and what's-what these days, concerning both manufacturers and retailers, so I figured I'd ask The Matrix here. I have a nephew that wants to start diving, and he's been messaging me (hoping I could still certify...

    Building your own IP gauge.......

    Though the little $10 Intermediate Pressure gauges sold by Leisure pro and others seem to get pretty decent reveiws, I read in a recent thread that you can build/assemble a much better one, for not much money. After doing a little digging around, I've found what look to be decent,economical...

    What's this grey plastic ring on the threads of new Scubapro HP hose ?

    I just got a couple Scubapro instrument consoles (new, but from ebay), and both (pebax) HP hoses have this odd grey ring at the base of the threads. The regular o-ring is on top of that, (followed by the disposable thread-protecting cap). This grey ring looks like something that would be...

    Question about odd hose on complete Scubapro gauge console assembly.....

    Hey guys, I recently snagged a couple new/un-used Scubapro consoles on ebay (they just arrived a minute ago) but I'm curious about the unusual hoses on them. At first I was concerened that these might not be the original hoses, but I was assured they were the original hoses, and now I see...

    O-ring picks: Brass vs. nylon

    A couple search attempts yielded nothing, so this seemed like as good a place as any for this. I'm looking at getting an o-ring pick, as reasonably as possible, just for occasional personal use (so I'm not looking to buy the most-expensive-best-of-the very,very-best.:D) The 3-pack brass kit...

    Pelagic-made Genesis computers made in China, or California?

    Even in the lengthy lists of details,stats,features,specs, some information of obvious interest can still be tough to find. I posted questions on the websites of 2 large retailers, and got conflicting answers. I was told the new React/Resource computers were made in the USA and came with a 2...

    Requesting advice/info on possible Genesis computer/compass/SPG purchase....

    I'm still (very) casually looking into getting a decent but basic, budget-oriented computer, and aren't looking as closely at the Aqua Lung i100 or Cressi Leonardo as I had been. Now the Genesis React Pro and Resource Pro have both gotten my attention (or more specifically, the current sale...

    Can a Zoop Novo be taken out of console, and have a strap installed?

    I would assume the console-mounted computer would be identical to one sold with a wrist mount, and that they'de be interchangeable, but you never know, so I thought I'd ask. (I'm considering a deal on a used Zoop Novo console, but like having the option of popping it out and making it a more...
