Having winterized regulators over the years -- primarily Poseidon -- I had been wondering whether anyone was still using silicone oil for antifreeze purposes, akin to the "Mares MR16 / V 16 Cold-Water Diving Kit" that I had recently seen listed, on a popular auction site? It seemed definitely...

Here's another blast from the past, from forty-odd years ago -- Poseidon's first stab at their "upstream diaphragm-actuated servo-assisted system" (which just rolls right off the tongue) -- the "Cyklon Maximum," which would later become various models of the "Jetstream," including "Thor,"...

Poseidon recently ran a recall of their older M28A computers, due to an issue with the two wet switches on the rear of the earlier models, and the threat of water intrusion, a malfunctioning depth sensor, and even failure -- and mine, which I purchased at a major fire sale, on the cheap, in...

Previous firmware updates, for Poseidon's M28 CC/OC dive computer, were akin to a root canal without all of the whimsy -- so much so, that DGX once ran a multi-page, multi-stage instruction sheet, a few years back, to avoid any gaffes that would, well, "brick" the M28, when the manufacturer's...

Offered here is a great collector's item, from three decades ago -- the Poseidon Cyklon 300 14K gold-plated swan-song from 1993 -- being sold on behalf of a friend of mine, who's even a greater Luddite than I and who also abhors the computer age, even though he had earned his substantial crust...

We purchased -- over-purchased, quite frankly -- a number of Shearwater products a few months back, and finally opted for the Teric, for its diminutive size and the NERD 2, with its heads-up display for use with a full face mask in less than ideal circumstances, which has lately been our lot...

So, a message arrived with my promotional emails this morning, from Light and Motion, who is now apparently flogging a new brand of regulator -- from Nex Underwater Products, along with that all-too common word soup of some "shared commitment to minimize their environmental footprint."...

I had wrestled with the notion of finally buying a nice yup-scale ultrasonic cleaner for some time, after going through a couple of Vevor models, from “LexCorp” over the years — each at about US 100.00, give or take; but decided once again to go the cheap-o route. Both of the recent cleaners...

For you Light and Motion enthusiasts out there, I have a question. Recently, I received a Sola Dive 2500 S/F light for my birthday and was wondering whether anyone out there had come up with some sort of lanyard solution for the thing? That ridiculous nylon wrist mount is a hard f****** no...

Here is yet another Rube Goldberg, decades-old cold-water fix from the folks at Poseidon, which was intended to semipermanently replace the top (secondary side, down to the springs) of a regulator, similar to some later designs, from the 2940-80s (Cyklon 300 and Thor) through the 2950-60 series...

Much like a contractor whose kitchen remodel is never quite complete, my gear is often the last in line for repair. Both were heavily-used Jetstream second stages which required attention -- one from my day-to-day gear, and the other, part of the Atmosphere full face mask, the "PP" (positive...

I have always had an issue with follow-through with gift cards / certificates, but recently had a chance to splurge on a pricey little tool (at US 82.50) with "funny money," since men have been unable to resist the lure of shiny new tools for over a hundred thousand years. This is a product of...

I once asked, during a Poseidon tech course, whether there was a bit of latitude when it came to IP settings. The answer, from the instructor, looking over bifocals at me, had been a terse "absolutely not" at the time and "pay attention to the manual" -- even though settings had changed a bit...

Falling under that category of "an embarrassment of riches," I recently came into the possession of an extra copy of Vance Harlow's 1999 Scuba Regulator Maintenance and Repair, which I would like give away to some lucky SB "DIYer" who will not immediately post it to eBay or gouge someone else...

I thought that it'd be a good idea to get a few FFM repair manuals on this newer forum -- for educational purposes only -- and not just those typical consumer "useless as t*ts on a bull" consumer versions, which are laughably bad -- some printed with red, yellow and green traffic light...

For those of you, who have never worked on the Poseidon Cyklon second stage, there was always an odd step, during reassembly, where the "valve piston" and its spring are inserted, within the LP valve housing and compressed, typically on a drift, while an o-ring remover, etc, was inserted through...

A friend, visiting from Baja, for the first time, since the covidiocy, brought along an older Cyklon 5000 of his, that had recently been "serviced" near La Paz, since he didn't quite trust Correos de México, their "occasional" postal service, to ship it to the States. Where to begin? The...

Here is the late, not-so lamented Triton 2000, an interesting though, apparently, costly experiment by Poseidon; and the only model of their second stages that had been discontinued. I found it interesting, at the turn of the century, with its compact, swiveling, omnidirectional design, and even...

GLITCH, GLITCH, GLITCH . . .

Here are a couple of true "blasts from the past" -- finally rescued from my dismal Bay Area storage unit, which had always reminded me of the "Your Self Storage," from The Silence of the Lambs. Among them, is a "Barakuda - Cyklomat," produced by Poseidon / Aqua Sport, some five decades ago...
