I dont want to piss you off or anything but a dive buddy of mine bought a aqua lung(US Divers) regulator and it almost cost him his life 2 times.. Freeflowed at about 90 feet in a quarry.. Then it froze shut as in not giving air at all on his 2nd dive with it.. I have heard bad things about the us divers regs so I avoid them like the plauge.. Thus the name USeless Diver..

Shut off?
Please explain how that could happen, and which model it was. Surely there was an official report on such a serious life-threatening malfunction.
Strange I haven't heard...

As we discussed previously, the Sherwood is a very innovative and competent first stage. They feature a dry bleed piston mechanism which keeps water out. It is known for being freeze resistant. The manufacturer is the same company that makes many of the products sold under other names.

The plastic USD second is pretty much bulletproof. Very simple design. It features a large diaphragm and levers for good mechanical advantage and ease of inhaling. You should find that it breaths dry and purges well. Just normal maintenance, and annual inspection for any hairline cracks in the plastic.

Price sounds way cheap.

My Conshelf 14 was rock solid for year after year of active diving.

I wish I still had it.

I've used the US Diver Conshelf during one of my AOW dives. I thought the 2nd stage was enormous, but I had no complaints with the way it breathed.

As with any used reg, I think you should get the reg overhauled at the LDS before you dive with it.

Rabbit, I have to say in my limited experience, The conshelf 14,20,21,SE all kick ***. Low maintenence and bullet proof. My only wish is that they had better material on the 21 second stage. You got such a good deal that you don't have to DX the sherwood 1st stage or the Octo.LOL I have dove the Conshelf 1st stage and second stage for 17 years, 5 years of that 80% blackwater for the US Army. I have had it ripped out of my mouth by tree roots in 4 knt water, twin 80's fall on it, and even slapped in my face by a 30# Grouper that just did not want to become dinner. The only reason I DX'd my Conshelf SE Octo is because my pit bull used it for a chew toy so it is not so pretty any more and When I was at the Zeagle Factory working on military gear with them they said ya wanna Air plus on that RANGER BC. Good deal get it serviced by someone you trust and it should give you years of service. ;)
Tgreaves, No offense bro but don't blame the equipment for not being adjusted correctly. A free flow at 90ft is life threatening to a newbie who did not remember how to fix it, or grab his Octo, or ascend. The free flow could be caused by a butt load of things, dirt, and improper adjustment, being probably 99% of it. Freezing up???? If you break ice you need to winterize your gear, my 21 (still my main ) is winterized. Locking up is again an adjustment. I am not saying it didn't happen but it was Operator / Maintainer error. Or a fluke not the USD name. They Navy, Army, Air Force, and even the Marines dive USD. You think they would let a Grunt go down with something that was not bullet proof??? Remember A look every year and a rebuild every five years or as needed and you will have NO problems.
JMHO Look me up in the welcome thread to find out where I come from.

I've got an OLD Conshelf SE2 and I love it. It's rugged and breathes very well.
Bought it from someone on ebay, had it rebuild and for 240 bucks I have a great regulator.

Well then stupid him for not having it checked out and fully serviced before he used it. And if he did, then it is to be blamed on the tech. These are bullettproof regs and they cannot be beat. They are still being made today in the form of the Titan. I highly doubt that it would freeze shut, and if it did, then he should have been using and envormentally sealed reg for the conditions he was diving in. I agree with Rick that there would have been some kind of recall on it if this happended and would be interested in seeing it.
Furthermore, The conshelf and its versions have been in existance for a long *** time and I don't think that your buddy was the first one to take one to 90ft.

They are great regs. Bulletproof and so far ahead of their time that they are still in the running today.
Now that all that junk about the first stage has absolutely nothing to do with you anr your reg because you have a sherwood first stage, it is the next best old reg. It has the dry bleed as mentioned and the only problem that you may run into is an original piston in which the Hp seat cannot be replaced and thus the piston is replaced. Still only $30 CDN. good deal for $50

maybe you should have asked these questions before making the purchase. The Conshelf series has been one of Aqualung best sellers. It may not be the most advance but it's a good "nuts and bolts" regulator. There has been problems with some models and they were recalled for upgrades to solve the trouble. The unit you purchase sounds like it was made from various parts of different rigs. That would have made me think before I purchased it. The good news is you can find parts and service for what you bought. The bad news is after you get it checked out by a repair tech you may find it would have been cheaper to purchase something else... good luck with it ..

Heck, if I'm not mistaken, they still make the XIV. At least, I have seen a lot of places selling them new.

I wouldn't be intimidated. In a sherwood, outside of the piston assembly, there is not a heck of alot that can go wrong and cost you a bundle. There are very few parts here. I have had many people in a similar situation to your with a mixed reg come it and yeah it doesn't look to pretty or match but it works good. The USD LP seat alone will likely be close to the cost of parts for the Sherwood first and second stage. I don't know why most of the conversation revolves around the USD as it is only the octo. The primary assembly is a sherwood if I am not mistaken.
Yes they still do make the conshelf (http://www.aqualung.com/products/conshelf_xiv.html), how many they sell is another story.

I dive with a Titan regulator and love it. Never free flowed, don't dive cold so I can't comment about freezing. It has always been easy to breathe.

OK ... lets all agree that he should take the regulator down to his LDS or service tech to be inspected. Buying used scuba equipment is like buying a used car ... you never know what you're getting until after you drive it around the block a couple of times. The 1st stage should be looked at to see how clean it is and if there is any worn or damage parts. The 2nd stages should also be inspected and adjusted. All this will probably cost between $40 and $60 plus parts depending on the shop. It's well worth it because you don't won't to be in a middle of a dive and find out about a problem the previous owner had.

I dive a Conshelf SE3. Never had a problem with it. Bought it in 1995, had it serviced for the first time in 2003. They can't be beat.

I also have an XIV that I bought on eBAY. Just got service kits for it and a service manual. My winter project is to clean and rebuild it. I'll try it out on my April 2005 dive trip.

So you were the one who outbid me!! ;)

I am doing the same thing. The more I learn about the old Conshelfs, the more I like them.

Like I said they are standard issue for the Four sevices and the CG (Yes the Air Force has divers :11: .) On our dive team we used XIV because of the Brass housing on the 2nd stage. I guess I cheat cause I was sent or rather Bill Brumiller came to our camp and gave the USD maint. class. I was the maint. guy on our team. Then I moonlighted at the local Dive shop in Niceville FL. So I got experience in a lot of gear. The only ones I didn't like working on was Mares. I have dove my 21 for many years and only one time had a problem when my outlet disc tore and I was inhaling some H2o. bad on me. used my OctoSE to finish the dive and during my down time till the night dive took the 5 minutes to replace the outlet disc and was in buiness again.

Agreed. A good shop that you are in good with will look at the thing for free and give you an estimate on what it needs.
