Yes, you are correct... but.... First, using air dil at 50 meters is not advisable... Most training agencies state that the PO2 of your dil shouldn’t be higher than 1.1 bar at maximum depth. That way, one can actually flush done the loop if the gas inside it becomes suspect. Additionally, the...

Umm... a Perdix measures 74mm x 83mm x 39mm... according to Shearwater’s website. Interesting concept - especially, the loading of custom tables. I wish the best of success with this project.

In regards to the nitrox tanks being off board, think about it.... one of the least appealing characteristics of some of the older SCR’s is the twin 7 liter (50 cuft) tanks attached on either side of the scubber.... HEAVY.... as an SCR does need considerably more gas than 3l. A big part of the...

The one unit did have the “Travel Tank Mounts”, with cam bands, vs. hose clamps, but that about it...

Mares/rEvo are expecting to make their big product launch, for 2019, at the Boot Düsseldorf show in late January... from speaking with Paul & Pieter.

Yeah... the B-17 is on my list to see! Were you on a dedicated charter or one of their Advanced Nitrox and Half-Technical Diving cruises?

Very nice video! Thank you, for sharing! What shop did you dive with? I'm wanting to dive Vis later this year... it looks like really great diving.

Just a guess, as a layman, I would think that any injury that negatively affects circulation could be deleterious in regards to DCS risk.... But, that should be confirmed, or refuted, by a medical professional...

Ummmm..... @rossh.... how many times does it need to be pointed out, and by how many people, that Don’s dive didn’t conform to the strategy that Simon has suggested might reduced decompression stress upon surfacing? Even Don, himself, said that he wasn’t attempting to emulate Simon’s strategy...

I have to say that I agree with the above. This thread has a lot of potential for educational value. And, I believe that a spirited discussion of various strategies, and their implications for such a dive, or any decompression diving, would add to that value. However, the fact that the proponent...

New price... $5500.00 I’d like to see this move...

Hello Max, they were made in a small batch by/for someone at Hollis. I don’t know if any more exist... sorry about that.

New price... $5750.00

Hollis Prism 2 Tek, with DiveCAN NERD monitor. This really is one of the nicest Prism 2’s that you’ll find, with just under 16 hours. It is the latest Tek version, with Petrel 2 controller and Shearwater NERD monitor. Also, it has Hollis stand and ratcheting tank bands. Deep Sea Supply heavy SS...

That’s a very cool video! Definitely, inspirational! Thanks, for sharing

Odd as this may sound, by occasionally going out on the commercial dive boats, with OC divers... and spending the day talking about CCR diving (but, hopefully, not in an egotistical way). It just reinforces that we get to do something rather special every time we get in the water.

For sure, all Petrel versions are DiveCAN... A friend of mine is looking to sell his very low hours Prism 2... it’s probably one of the nicest ones I’ve seen, with many nice extras (NERD monitor, Hollis stand, ratcheting tank bands, etc...). PM me, if your friend is interested. I’ll be posting...

In the spirit of the title... I’m looking for a RMS scrubber cassette, or two.... and, TBH, looking at the markup on OEO’s website, it’d almost be cheaper to fly to Belgium and by direct... However, if I can find someone who’s got one,or two, languishing in their spares kit, and would like to...

I have a set of Hollis valves that need a new home...

By definition, drowning is "the process of experiencing respiratory impairment from submersion/immersion in liquid." As such, a hypoxic or hypercapnia event whilst submerged would be a case of drowning, regardless of a lack of aspirated water. So sad to hear of something like this happening...
