    People embarrassed to do pre dive buddy check?

    The first clue that you need a buddy check is that you state turning on the Oxygen... inexperience and reluctance to seek advice leads to problems. When I first started diving, everyone had everyone's back and it was common to interact with other divers to insure equipment and dive planning was...

    New Toy - Airetex 45 w/ CB Nitrox

    Still running like a top. I had to replace one one the piston diaphragms in one of the compressors running the pressure swing input manifold. 20 bucks. As an aside... One of my dogs developed fluid congestion around his heart and had a hard time breathing while we were trying to medicate him...

    Best material for building a blending stick.

    You can buy a gas turbulator cheap and incorporate in into the compressor intake with a solenoid to shut off the other gasses when the compressor goes down. Pictures: Another: And another:

    Autodrain settings?

    Muffler insert slides up into a same saize union inside the lager pipe creating a "skirt" just like a muffler for a combustion engine.

    Autodrain settings?

    I built a manifold with a smaller diameter pipe inside drilled with holes. All 3 of the drains tap into the manifold forcing the air through the pipe with holes to reduce the sound. The manifold has a drain that I attach a hose to to move the water outside of the garage. I have a picture around...

    Why O2 before Air for PPB Nitrox?

    I think what you are seeing in the dive shops is the NITROX fill from a bank, NOT pp blending. A big difference between introducing 32% and 100% into a possibly contaminated tank or valve.

    What is that Noise

    My guess... If you hear the sound at a constant level, and is in rhythm with your breathing and seems to come from behind your head.. it might be the first stage seating and unseating. I have a piston regulator that seems to click in very cold water.

    Just ordered new tanks - anything to note?

    6 - 133's.... you are not playing around. Buy a pack of paper 3" stencils and spray paint an identifier (clean the surface with acetone and use enamel), just below the shoulder on the back side of the valve so it can be seen when mounted and seen from the top among standing cylinders. It is...

    Catastrophic BCD Failure questions

    One other thing to consider... If the hose was extended, and the cable extended too, you need to consider a longer inflation pressure hose as well. When you pull on the dump valve hose and the pressure hose is too short, it will pull on the first stage preventing the cable from loading and...

    A word to the wise when dealing with any enforcement authority...

    Never provide information unless questioned and never provide an answer to a question you are not sure of. Last week coming into Cancun, we went through customs and pushed the "button" which turned Red. My wife and I were herded over to an inspection table and they started going through our...

    Accomodation in PDC or Cozumel for diving in Cozumel

    Unless you are stuck using a timeshare in PDC, Cozumel is your destination. Most all the resorts have gone all inclusive which is a rip off if you are active and away from the resort, Cozumel resorts are the same way. Aldora Divers has a 7 night partner hotel and 5 days diving w/free nitrox for...

    Video Cozumel April 2018 with Tres Pelicanos (3P’s)

    I'm thinking you might be talking the "safe second" ID. On my Sport diving single tank rig, I have one (my best breather, SP S600) normal face-plate, but on a yellow pull-free necklace and served by a yellow 6ft. long hose... tucked between me and the wing. This is the one out and I'm using. It...

    Can your compressors for air on the go..... New tech replacement!

    I was on EBay looking if someone was wanting to part with a Scubapro Muli-tool and low and behold this pops up. I wonder how many will fall for this? Smaco Mini Diving Scuba Cylinder Oxygen Respirator Tank Underwater Breath Tools | eBay I sure would like to get look at how that is made -...

    Mule needed

    Just out of curiosity... Have you tested the cost of just having it shipped back to you? Back in 2010, I had my backup prescription mask which was left on the boat shipped back to me from Grand Cayman for 18 bucks and that was air. Of course you would have to have a cooperative dive op go to...

    Old steels denied fills due to store "policy"

    What was said about tanks being up to the job by conforming to the DOT inspection and testing requirements is absolutely correct. The presumption that the testing is done by a "fire extinguisher" shop is somehow deficient lends to my conclusion that you don't understand the industry or the...

    Exploding pressure ?

    Hydro's are usually at 5/3 the rated pressure. The expansion and subsequent retraction of the tank has to fall with a certain percetange. You would have to go well beyond this unless there is a problem with it and failure is imminent.
