Same gauge and same price as DGX. My experience with Piranha has been very uneven. I’ve never had anything but positive experiences with DGX. I’m not saying I wouldn’t buy something from Piranha if I needed to: I have before and likely will again. However, I know where I would prefer to buy...

Wow is that expensive! For me, the first place I always go is Dive Gear Express. They don’t carry everything, but what they do carry is usually exactly what you want to buy. If they have it, I’m pretty likely to buy it from there. Here is the generic one they carry. It’s all of $17...

Others have harped on it, but I’m going to as well because the information is so inaccurate. This statement above is 100% incorrect. You are making a very fundamental flaw and comparing compressible gas to incompressible liquid. You’re right in that 1 gallon of water going into a hose means 1...

If you’re planning on doing more than one dive a day, it’s usually traditional to use a set of doubles that will handle what you’re looking for. So, if you’re doing two dives and can’t do it with a single set of LP 50s, do it with a set of LP72 or HP 100. I mean, if you want to have a couple of...

tl;dr at bottom. Yup. Both statements can be equally true. My personal belief is that both statements *are* true. Increasing your personal capabilities, understanding your own equipment, etc. all lead to being a safer diver, which lowers the chance of injury. However, if you do not do either...

Practically, IMHO, none. I’d never own LP tanks without being able to get at least a *moderate* overfill. Otherwise I’d buy the HP (rough) equivalent and get the capacity. However, there are tanks that don’t have a direct HP equivalent: LP50, LP72, and Faber LP85 (with the narrower diameter)...

Umm… dive it? :) Seriously, these are industrial-grade cylinders. It will outlive you, even with its flaws… ETA: here’s a tank I bought. Cleaned off the corrosion. Hydroed it: passed just fine. Do not worry about such microscopic details…...

As someone who has put some time into creating a list of tank specifications, I can agree that what we see in print often has very little resemblance to what we might experience in the water. :( I’ve seen tanks manufactured by the same company (Faber), but distributed by a different company...

You say that ironically, but I think most people would say that earnestly. Why would you invest more time, effort or energy into a task than you have to that you’re only going to do once? Or very infrequently? And given that the safety statistics for scuba are both really very, very good and...

I’ve experienced the same thing and I have been told it is a tip thing. They feel that if they don’t take care of your gear every time you won’t feel obligated to tip them, and they want — need, really — to be tipped. My problem was: I didn’t like the way they were treating my gear…. :(

I swear I read that twice as “aloe – infused Chairman“. And I thought, “who in the world wants to infuse Pete with aloe, and what exactly do they want to do with him?“ I’m not at all sure I want the answer to any of those questions. ETA: In fact, I am certain I do not want the answer to those...

My understanding is that Eagle does not actually build the “compressor” per se. They buy a different manufacturer’s compressor head, usually Bauer, and then just assemble all of the pieces around it. Mako compressors are similar: either Bauer or (more recently) Reavell in their case. I’ve seen...

That is a point worth repeating. The current Faber coating process is different than the older process. That’s why I’m careful to call them epoxy tanks, *not* painted. Painted tanks are awful. OMS-branded Faber tanks are well known for rusting. The yellow is a dead giveaway: the epoxy has...

I'm a huge fan of hot-dip-galvanized tanks. I'm a pretty big *opponent* of painted tanks, *especially* steel tanks. However, the Faber epoxy tanks aren't really "painted". You can read about it in more detail, but it's a galvanized/epoxy/clearcoat process. It's *very* durable. Objectively...

Here is a quick write-up of my carbon monoxide (CO) calibration / bump-gas setup. I had previously written up my experience as a comment in a different thread (see below for details) but it's poorly named and spread across multiple posts, so I thought I would combine it all in a single...

Grainger. By far the cheapest source I’ve found. Edit: I was tired of nobody (including me!) being able to find my comments about CO calibration, so I wrote it up as its own post: Carbon Monoxide (CO) calibration / bump-gas equipment and setup Hopefully, this will make it more findable (and...

I should have checked that. And that makes buying Chinese tanks a lot more understandable. Sorry for my American myopia. :-) I’m not certain, but that might have more to do with covering the tanks that have already been made than expecting new tanks to be made that way.

That’s always the problem with buying things made in China sold by a Chinese company. Really, that’s always the problem buying things made in China (and elsewhere, including the US), but at least with a US company there is hopefully somebody doing quality assurance of the items that has a little...

That is also the GUE standard for recreational diving. I recently made the mistake of diving a 6 foot hose. That was stupid. It was too long to simply wrap, and too short to conveniently put under a canister. I have a long enough torso that I just left it wrapped and it wasn’t that much of a...

Dark water sucks. Actually, any water you can’t clearly see in sucks. My least favorite dive on earth is 18 feet deep in a nearby inland lake. The water is green, you can’t see anything, and they have sunk things for diver entertainment. You know, boats, equipment, things like that. The...
