    Question Argonaut Kraken Owner

    Depends on the reg, who set it up and how it's dove. Granted my AK was tweeked a lot but it was put on a modern test machine and had test ran on it. It beat top of the line Scubapro and Atomic regs by a good bit, so much so the shop ran it a second time because they didn't believe the results...

    Question Argonaut Kraken Owner

    Once the quarry warms up a little, I'm sure they guys will be itching to get wet. There are 4 of us who regularly dive DH hose regs....and a new guy just learning so make that 5 of us. Always happy to help a new DH diver. Biggest thing you need to look into is a suitable BC, it needs to...

    Question Argonaut Kraken Owner

    The Kraken is at it's heart a Conshelf and with the exception of a couple of common orings, all of the normal service parts are the same ones in the Conshelf (as well as almost all AL/USD diaphragm regs) so as long as Aqualung is making parts, service parts are available. It's not hard to...

    U.S.Divers Mistral sizes

    I will need to look but I'm pretty sure its the same as some other USD regs of the era. If so, it's a CUSTOM size thread with a 20 tpi pitch. You will have to custom cut it or buy an expensive custom tap if it's what I think it is. Pretty sure I have a body I can check and seems like I have a...

    Submersible IP gauge?

    You can as long as the gauge is not sealed (back working parts in ambient pressure), most are not sealed with SPG's being an exception, it will work . SPG's are sealed and are effected by depth but the difference is not really important, does it really matter if a gauge reading 3000 psig if off...

    Question Identifying reg and old tanks from the 60s

    It's unlikely anyone will touch the reg, no factory parts but it's a basic flow by piston so there are 2 orings and a HP seat in it. The orings are common size I'm sure and the HP seat is most likely OK and/or it can be flipped. Odds are also good a SP MK-2 or Sherwood seat would work. It's...

    Question Are most people confused about unbalanced first stages?

    I's still around sir but not as much as the old days. To answer this question, first you have to understand what balancing is, what it does and the difference between balancing and depth compensation. You also need to understand the difference between psig and psia. Basically, psig...

    Who is Herman?

    Just so I was clear, the plunger can be most any material , the forcing cone is what must be of a harder material .

    Who is Herman?

    I answered him via message but figured I'd chime in. I no longer make tools but last I heard you could get it from Aqualung IF you can get a dealer to order it for you. One thing I would HIGHLY caution about is making it from anything other than steel, mine were stainless. Reason being is...

    Question Is a 20 year old regulator safe to use?

    Ahh come on Mark , I see those red AK hoses. :) Had to razz you my friend . I dive a lot of older regs, both old double hose and single hose. Bottom line is, if you can get parts and it has been serviced, there is no reason at all to not dive an older reg and IMO, the quality and materials...

    PRAM build...

    Did a little digging, the pin is 0.060 diameter, 1.33 in long and the spacing under the pad is 0.040 in. Pretty sure I cut them out of 1.5 stock. The length is best cut a little long and tweaked in rather than cutting to length the first time. The length is not super critical but it's a lot...

    PRAM build...

    I put this on VSS but I'll post here too. The Phoenix should have come complete with a pin, pad, gaskets and all of the internal parts (the internal parts are the same as a Conshelf or Titan so those are available), if you didn't get them, you will have to. Most of the stuff from a Titan or...

    Question Argonaut Kraken secondary leak adjustment

    While not the approach I would normally take, it's possible to replace just the HP seat, they should not be hard to find as 90% of all UDS/AL regs in the last 60 or so years have used the same seat. The hard part is getting the springs and balance chamber back in without the proper tools. IT IS...

    IP issues with RAM conversion

    I suspect you might be chasing the wrong problem, a leaking balance chamber (scratched, dirt or bad Oring). will allow the IP to creep up as well. Are You sure you have the correct oring in it , the backup ring in the correct place and many BU rings have a specific way they go in so that needs...

    Wells Marine First Stage Part?

    According to an earlier thread, the reg is a re-branded Aqualung Micron .....I have no idea if that is correct but if so a Micron pin will work. An AL dealer can get them.....odds are service kits are a lot cheaper too. https://scubaboard.com/community/threads/sidewinder-first-stage.614147/...

    Electric in Bonaire

    Been on Bonaire many time and never needed an adapter or converter. However I always bring an outlet strip because most places don't have enough places to plug things or it's in the wrong place.

    Got my first ever DH reg

    It may or it may not, there are 2 types of threads on the AK, the early ones had a standard US Diver thread (custom for USD) , the later ones had a metric thread. Which you have I can't tell just be looking at the photo . To be honest, unless you have a really good reason for DIN, just stick...

    Royal Master conversion to Royal Aqua Master

    If all you are trying to do is convert a DAAM to a balanced first stage, just to find a RAM nozzle and replace the nozzle in a DAAM. The pin will also have to be replaced but rounding up those parts is not hard using Conshelf or Titan parts. I know I have some DA nozzles but there might be a...
