happy new year to all! i would like to re-open the old dicussion on the military non.mag regs. i recently picked up a u.s. divers aquamaster doublehose non-mag on ebay and i would like to find out all i can on this regulator. i have read the old posts from guys like SDM, searat, byran, etc.. the disscussion that was posted then, mainly identified what regulators where made and what kind of outside finnish was applied to them to make them non-magnetic. but what about the guts? i would like to find out what might be special about the guts in these regulators and what special care we might have to take with them when rebuilding them. i have consulted with dan, grandmaster of VSS, and he has told me that there were gold plated parts in the nozzle? if anybody can post new info on these i would really appreciate the input. thanks, vintagemike  inland divers vintage dive club |

Talk with Bryan at vintagedoublehose he knows a lot about them and owns several that are diveworthy thanks to his expert workmanship. I also think he has a few military contacts that have provided him with a lot of info and may still be in touch with him. I have one myself and I think it is the deal and quite the conversation piece.
Bryan also has some pics of his NON MAG in action at the Toledo Bend trip on his web site.....Check it out.

A lot of what I know came from Dan, Sam and Ron Miller. I have some contacts that are current and former Navy EOD guys that have given me all the info that they could remember or could scrounge up on them. They were also able to supply me with some spare parts. The regulators that I have are a brass/bronze combination inside and out. Various combinations were used to get the lowest magnetic signal possible. The testing procedure is very long and complicated as I understand it. Standard DA Aqua-Master parts will interchange and will work just fine but would not be correct for the regulator. Nylon as opposed to phenolic gaskets were used,the diaphragms were a bit different and the hose clamp screws and nuts had were brass as well. Hope this helps

hi byran, thanks for the info. i am going to contact you at your home web-site. i think the one i picked up has never been opened. the hoses and duckbill were petrified and i am worried about the diafram because the two case halves are really stuck together, even a B.F.H. made no difference, just kidding about the B.F.H. . the one i picked up has a (trident stamp)? on the yoke and the body, not the case, the body. do these stamps really mean anything? and thanks to rob for referring me to you. i would really like to make that florida diving you guys are planning. this year at wazee you must borrow my farallon to payback the kemps cow. thanks, mike  |

The trident stamp means that the regulator has been tested and certified as non-magnetic by a Navy approved testing facility.

Right on the money as usual Tom (sorry about LSU  ) I've never seen one that had the case stamped so that's not a big deal. Cases are really too thin to take much of a stamp to begin with. I have seen a few that have the trident scribed on the cases. Bear in mind that this trident IS NOT the same as the SPECWAR (Budwiser) trident. This is a symbol for the low MU magnetic signature of the regulator parts. According to my sources the regulators were on a regular schedule of checking the magnetic signature and all had to be re-certified each time they were serviced or repaired. I've seen case halves pinched together either with pliars or by being smashed or sometimes the diaphragm simply deteriorates to the point it becomes soft and acts like an adhesive and holds the two halves together. Very similar to what the duckbills do when they are allowed to rest against the top box for years! Damn near impossible to remove.... E-mail me if I can help. |

thanks to tom and byran for further info on the non-mag. byran, could you post any pictures of the various stamps found on the military double hose non-mag reg's? it would be nice to have a picture reference for the future when trying to i.d. these regs. when they pop up on ebay or at byran's scuba double hose garage sale. thanks, mike |

I don't have that information all in one place yet. I hope to make a page dedicated to these regulators on my site in the next few months. Stay Tuned!

Hi Bryan and Rob,Someone saw the Kemp;s Cow using a nonmag reg in Christmas Lake a few years ago!
He is a Navy Cow too!

Does the Kemp's Cow use two or four fins?
