Viton is good if not absolutely necessary, but do it for peace of mind, and it's fun (Yippee, I converted my own reg). If your first stage is a piston I suggest you get the factory O ring kit. One never knows if the aftermarket vitons have the right durometer rating for particular apps.

I had never heard of this problem until about 5 years ago. A friend of mine would make a puzzling remark that he wished he could stay level as easily as I. He eventually went to ankle weights and is happy with them. I still don't know what the specific problem is. He says it is the same with...

Evidently, the "DIR" divers are required to use soft weights. Otherwise, I don't see how they could ditch the belt. A DIR afficionado named Wendy, who dives with wings (including crotch strap), claims that if she needs to drop the belt that she can simply pull it through and drop it. I don't see...

Have you tried your new reg???

Rodale's tested the Atomic fin in two versions including an "EZ Kick" which was more flexible of the two. Both models had the same basic performance. They said the sizes run large. Also, they intended to test the unusual quick release buckles for durability.

Pug, the pumps are hard to find nowadays. Occasionally they show up on E Bay but the prices and condition of the item are individually or collectively subject to question. The buyer really has to be familiar with the mechanics and what questions to ask. Many years ago, these items were...

OMS's "captured O ring" is the DIN 477 system. Should be compatible with Genesis.

Aquamore, I agree about the ultrasound, but bear in mind that ultrasound is used in laboratory experiments to initiate rectified diffusion (bigger bubbles). About the formula, all that says is that frequency and wavelength are inversely proportional. So, what's new? Does sound a bit like...

Sulaco, don't feel bad about the razzing. Heck, my compressors are home built, sort of. In years past, the performance of commercial units was pathetic. You had to pay a lot of money for a clunky 100 pound portable with cast iron cylinders, crappy filter, which would only put out 2.5 cfm. So, I...

Sulaco, for that money you may be able to find a SCUBA compressor with condensator/filter and be ready to go. Just because you're on a budget doesn't mean that you have to settle for a "jurry rig". Look for a 3.5 cfm/3500 psi, or better, unit on E Bay or in the classified. Six months ago, I...

I bought a new SP G250 over two years ago and it was delivered with Christolube, standard. I didn't know what that white stuff was that was showing through the ventilation ports, until I wicked out a bit with a toothpick. It is standard on their regs. I suspect it is becoming more common.

Stone, if the high end Genesis has oxy compatible grease and monel parts I wouldn't hesitate to use it for oxygen service. A lot is made of O2 "clean" but I think the whole scene is overblown(pun?). Documented regulator fires are rare and seem to involve first stages which were packed with...

Armied, you will need a small crescent wrench and some soapy water. Remove the plug on the regulator first stage marked "HP". Attach the console hose end to the hole marked "HP". Screw it in by hand and snug with the wrench, just snug so it won't back out. There may be a hose protector which...

BillP, thanks; the article goes on to say that spines broken off are absorbed, and doesn't refer to the broken spines as "pigment". Pigment would wash out with the blood anyway. As far as infections, the article says "IF" infection happens, do such and so forth. There are a lot of ifs. From this...

Unfortunately, the BC designs which followed the patented SP stab do not always afford consistent positioning and stability. The crotch strap addresses these inadequacies. The wings harness is a retrograde copy of 1950's style gear. One problem with the stab is that it is a one fit device. If...

Let's not get too excited by "froth". Even an athletic diver shouldn't transfer enough bodily energy to cause excitation of micro nuclei and stimulate a small bubble, at least not through rectified diffusion. I also get the impression that Dr Deco is ambivalent about the role, if any, that...

The question you're asking harks back in time to when diving began. The early harness systems used a crotch strap to center the tank and prevent the large diameter double hose regulator from bumping the back of the head. Most divers didn't like this strap for several reasons. So, when the...

I'm seems as if the weirdness evidenced when surface breathing new regs is more common than in the past. I have a SP G250HP and AL Cousteau. Both breath a little strange on the surface, but not when submerged where breathing "feel" becomes quite smooth. On the other hand, my old SP adjustable...
