Here are the pictures. There is no sign of corossion or grunge anywhere, which is what I expected from the description. The seat is pretty engraved though. I thought the latest poppet came with two o-rings. This one only has one? Is it still the style where I can replace just the seat? I...

The pictures clearly show a metal barrel with a retainer clip, so I am pretty sure it is a G250. Thanks for all the tips. I will let you all know how it goes.

I presume you are just talking about soaking in water so as to avoid removing any lubricant. Another piece of information is that the person I bought it from claims only to have used it in fresh water. Is there somewhere in particular I can look to verify this claim. Ie somewhere that prudent...

I just bought a new-to-me G250. It looks brand new in the pictures, but I know it has been shelved for 8 years. I think it was made around the turn of the century. It looks like the G250 HP except that it is a G250. I have the schematic for the 109, and the G250V. I am pretty sure that the...

All of which are during maintenance tasks. There are virtually zero elevator related deaths from normal use ever since Otis invented the braking system that, in its modern form, is used in all elevators in the world....and five more characters. ---------- Post Merged at 03:38 PM ----------...

Actually, freediving you should never let go of your breath (except what you require to equalize your mask and ears) until you are at the surface and have air available for another breath. This is a huge rule because you carry the majority of available oxygen in your lungs.

You cannot die from breathing too much helium or any other inert gas at 1 atm unless you fix it so that you continue breathing it when you are unconcious. In order for it to kill you, you would have to continue breathing it for several minutes after you passed out. If oxygen is added, it is to...

Awap: Would you not agree, however, that while servicing your own regulators is certainly something that can be done by most mechanically inclined people, it is not a cheap and easy alternative to taking them to your LDS. You need to become very familiar with how a each stage functions in...

I have never heard of any reason why gloves are necessary in cold water other than comfort.

I dove on a beautiful reef today, and I learned some things, and I wanted to share something that I already believed. I dove with a novice dive buddy (6 dives), and we had discussed diving together the week before. I felt that I would much rather dive with someone who has 6 dives, and will...

First off, a reg of the age, in a completely unknown condition does not need to be "checked out". It needs to be serviced. This entails replacing wear parts (seats and a few o-rings), cleaning metal parts, and careful inspecting all of the other o-rings (or just replacing them). There is no...

I see a filterscreen. It's the sintered metal bit below the star washer.

Follow up question. Any reason not to use the second stage from your pony as your octo?

The "when filled" part won't work as the tank will be negative at that point. Subtracting the difference in air weight from the "when empty" part will, however will give you this value.

Taking a course with dives is absolutely crucial to getting value from it. It really isn't rocket science, and is something that could be easily self taught. If you have to pay $200 for the course, you might as well get a couple of free boat dives out of it.

You dive nitrox to decrease your effective depth for nitrogen. What you do with that decrease in EAD is up to you.

I tried the frog kick two weekends ago and it surprised the heck out of me. In surge I was used to kick kick kick kick kick kick gliiiiiiiiiide. With the frog kick I got kick glIIiiiiiiiiiiiiiiiide, wait for my buddy, kick gliiiiiiiiiiide, wait for my buddy.

Assuming you were in some sort of quarry, I would be concerned about some bug crawling up inside of you, and giving you a serious infection. Be careful that relief from your treatments isn't masking a serious bacterial infection.

You will never get people to stop putting their kids in the bed of their pickup truck, you will never get people to stop texting and driving, and I am afraid that very few people who are determined to go into an overhead environment untrained and ill-equipped will be persuaded by anything you...

I second practising in safe waters. It can be quite tricky until you get the hang of it. I taught myself in a local quary over the training platforms.
