    For Sale Andy's Trilam Front-Entry Drysuit Size 2XL

    Here is a trilaminate drysuit for sale in excellent condition. The person who bought it ordered it without getting measured and ended up with the wrong size drysuit. They ended up getting a custom-cut suit and practically never used this suit. It's in very good to excellent condition. The...

    Deco tank valve recommendations

    Leaving aside all discussion of valve wheel colors, regulator colors, hose colors, left or right bottle carrying, etc. and just focusing on the valve: I would recommend having a “Pro” convertible DIN/yoke valve on all of your tanks. Obviously back mount doubles are going to have an isolator...

    Shortage of hot dipped galvanized tanks in the US?

    And I just sold 12 steel scuba tanks… Congratulations to those who got them. Not sure I would’ve sold them had I read this first. :-) Of course, when I look at how many I still have left… Yeah, I’ll be OK. :-)

    Why dry gloves are in blue color?

    I prefer the Ansell cut resistant chemical resistant gloves: here’s a random link. https://www.safetycompany.com/test/ansell-alphatec-gloves-pack-of-6/?sku=AN-58-735-010 I like the cut resistance for the large amount of zebra muscles we have here in the Great Lakes, and they’re much less stiff...

    Question Oil selection for Poseidon compressor

    Well, Dana at Poseidon compressors in Vermont is still answering the phone on occasion, so you could try to ask him. But as a fellow Poseidon compressor owner, here’s what I can tell you: When I bought mine, it came with a container of “Poseidon 751”, with the Poseidon Vermont company address...

    Question Took my first deco, help me to understand my computer behavior

    Sure. I went and dug into my logs. Turns out I usually *had* bothered to set the Oceanic to the same Nitrox gas as the Shearwater. In most cases, the Oceanic simply never went into deco and the Shearwater did, so of course it didn’t get bent. Like I said earlier, when I started diving the...

    What do double HP 120s weigh

    You’ve seen the numeric answers, and the Updated SCUBA tank specifications list -- in PDF and spreadsheet can give you details about other tanks. For me, there is a noticeable difference between double HP 100/LP 85 and HP 120. The extra weight above what is already a heavy load is really...

    What Color Tank Should I Buy?

    Ah, the joys of tank ownership. :) (ETA: It’s really more accurate to say: Ah, the joys of your average local dive shop…) It’s traditional that if a valve is removed from the tank that you need a new visual inspection. Do you really need a new inspection? Well, seeing as there are no legal...

    Question Took my first deco, help me to understand my computer behavior

    I know you’re making a joke, and that that statement does have a significant amount of truth to it, but that was something that was definitely a change of mindset when I switched to my Shearwater. Previous to my Shearwater I had an Oceanic computer, which are pretty well regarded as the most...

    Question Catalina AL80 Tanks

    My *exact* thought. Think of the impound scene in Liar Liar.

    Question Catalina AL80 Tanks

    You’re asking a question that we can’t answer. But I’ll try. :) As for Catalina and the “bad aluminum“: my understanding is the same as yours. Catalina never made tanks with 6351 aluminum. I don’t have an official reference from Catalina, but here’s some confirmation on a previous scuba board...

    What Color Tank Should I Buy?

    Despite being your typical ‘serious’ tech diver, I honestly love the look of brand new exotically colored aluminum tanks. Candy apple red, metallic purple, electric blue… Whatever. Love it. Never mind the fact that I no longer dive single tanks or aluminum as my main tanks. They’re just...

    Cave diver drowns - Jackson Blue Springs, Florida

    Thank you for this, both asking Edd directly and your description. I loved panic diver on the surface in my rescue class. And the concept you’re conveying really translates: grab their opposite hand, spin them around and grab them from behind. You’re not actually doing that in this case, but...

    HP QD Connectors

    My solution is to use stainless plugs with brass sockets. Solves the high-pressure denting problem. If you are going with pure O2 and want to stay brass for compatibility, I don’t usually find the denting problem too difficult to deal with. The biggest problem I have is I sometimes have to...
