Questions & Answers

JASON S : What are the differences of the Z3 and the B2 Stage 1? I was told they are the same exact part, looking to confirm.JOE S : The B2 has a swiveling 5 port cap for the LP hoses. The Z3 does not have the swivel component.
KEVIN C : This is open box that is all meaning never used except display ??? Also environmentally sealed? Im am thinking it is worth the extra money to get it sealed?KEVIN F : It's a store display model that does not have the box anymore. Never used. Not environmentally sealed. Get environmentally sealed only if you plan on diving icy waters or if you plan on diving very dirty or contaminated waters.Daniel R : Not worth the extra money if you will be diving warm water. IF you plan to do cold water and warm water then would prefer sealed.JEFF C : It takes a lot to screw up an Atomic... I'm a professional working MSDT who Dives everyday all year round in Hawaii. It's a great Reg, but if you don't dive as much as I do or even 100 times a year - it's way too much for the average recreational diver. That being said - I have 2 Atomics and I love everything about them.
RANDALL M : is this regulator ready to go out of the box, or do I need to have it "set up"? Also which Seacure mouthpiece works on this regulator?JEFF C : This Atomic Reg is NOT ready to use out of the box! As are most! Remember when you buy a 1st stage alone or with a 2nd stage along with it you're still missing 3 important things to dive safety. There's no SPG console(High Pressure) included. There's NO alternate air(Octopus 2nd Stage and there's is NO power inflator hose(Low Pressure!) As a certified diver you should hand all these things and then some. As far as mouthpiece's are concerned that's just a matter of preference - this 2nd stage primary unites with almost all mouthpieces. So that's just a matter of "feel" or "comfort." I'm a working dive professional who does 4-6 repetitive dives a day - sometimes 7 days a week so, I prefer something strong and rigid. That's up to you. This is is a Top of the Line Regulator! I would tell the average recreational scuba diver that it's a bit much for 3-5 dives a month, but if it's quality you want & money you have - this is as good as I think it gets. Maintaining it with care and proper storage is everything! I hope this helped... Dive safe & Dive Smart! Aloha, JeffONUR B : You would have to connect the hoses. A small adjustable wrench and some silicon lube will get the job done. Never used a Seacure mouthpiece, so I can't comment on that. This is a great product by the way. I have used it in both cold and warm waters for many years and never had an issue.LAUREN S : Check out the regulator size chart on the Seacure custom mouthpiece website.RICHARD BRAD R : Yes, out of the box and good to go. Great regulator. Not 100% certain, but different mouthpiece should be no problem. Make sure to position vinyl tie wrap correctly. I have great comfort in using the mouthpiece sold as is.......why replace?
Steve K : Does the Z3 for $529.95 come with a sealed first stage?YAN G : No, this is the sealed version: <a href="http://www.leisurepro.com/p-atmz3sy/atomic-z3-sealed-swivel-regulator?RRref=productPage" target="_blank">http://www.leisurepro.com/p-atmz3sy/atomic-z3-sealed-swivel-regulator?RRref=productPage</a> .
Shopper : Does the first stage have the LP swivel?Jon A : The first stage does NOT have the LP swivel but there are 6 evenly radially spaced LP ports.DOANE K : Nope 2nd stage -- works like a charmYAN G : NO, the Z regulators do not have a swivel. They are a fixed first stage.SANDRA K : If I understand the question correctly, yes it does. Very nice regulator. We're very happy with it.

200 + dives and still as strong as new

I purchased my Z3 with a Z2 alt. I put in 175 dives in 74 days in the water. I have had no issues what so ever with either reg. I have been in every position I could get in underwater, head down, head up, upside down, and any other position I could get in. I did have a raspy sound when face up in the prone position, but no leakage. I frequently position myself that way when under wrecks or reefs. I am considering purchasing two more Z3s to make a sidemount rig with. To say I am pleased with my purchase is an understatement. Worth every dollar I spent.

Good, but not as good as I thought

It was a good product, but when you breath upside down, the reg can get a bit raspy and water leakage often occurs. Also, the swivel is prone to getting "stuck", where it no longer moves smoothly. A good thing is that, as advertised, the bubbles do steer clear from your face. All in all, a good reg, but not necessarily worth the money

Atomic Z3 Regulator with Sealed 1st Stage Review - $569.00 - Scuba Gear Customer Reviews

This is a very well manufactured regulator. I have just logged 20 dives on this since I received it a couple weeks ago. This REG is very easy and effortless to breath. The first stage does have a unique way that the lines connect to, but it does not cause any discomfort or problems whatsoever. I would strongly recommend to a friend.

Great Regulator

Easy to assemble. Has so many ports, too many for us but maybe good to have in the future.

Great Regulator

This is a great regulator. I love it. The only thing to consider is that if you ever think you might decided to use a high pressure tank (and you probably will) get the DIN valve on the first stage and buy a yoke converter. I switched mine useing a DIN converter kit, which was easy enough, but taking that off and putting a yoke back on requires having the right tools and ideally you don't want to do it too often. However, attaching a yoke converter to a DIN valve is easier. You can put it on and take it off with no tools if you need to. For a few extra dollars I think it's worth haveing the flexibility and convenience.

ATOMIC Z3/YOKE

By FRANCISCO Q.

excellent. perfect for me especially since I have given up on cold water! (getting older)

The Atomic Aquatics Z3 is a compact and budget-friendly regulator that outshines even the most expensive competitors. Based on the B1/T1 platform, it offers the same performance and patented features as the Z2, plus some extras. Its balanced flow-thru piston design uses a high-flow stainless steel piston and a self-lubricating high-pressure piston seal for low maintenance. The unique jet seat system prevents seat damage over time, and the precision-machined valve seats enable a 2-year or 300-dive service interval. The Z3 excels in diving performance even at low tank pressures.

Freeze-protected and factory-sealed, the Z3's first stage prevents silt and sand contamination. It's Nitrox-ready up to 40% and features 2 high-pressure and 7 low-pressure ports.

The Z Series second stage boasts a balanced linear flow design for effortless breathing at all depths and conditions. Built to last, it features a Zirconium plated brass demand valve body, titanium lever, sealing orifice, and high-quality silicone rubber diaphragm. The patented seat-saving dynamic orifice extends the life of the second-stage poppet seat when not pressurized.

The Z series second stage is equipped with Atomic Aquatics' patented automatic flow control (AFC) for optimal breathing resistance. A soft over-molded rapid adjustment knob is available for special situations. The titanium comfort swivel eliminates the "pulling effect" when turning your head underwater, allowing 30 Degree rotational movement without binding or kinking.

The Z3 offers a high-flow second stage case, magnum lever design, dual material second stage cover for easy purging, and a dual silicone comfort fit mouthpiece. It comes with a 3/8" threaded 32" low-pressure hose, weighs 2.6 lbs., and includes an owner's manual. Experience the exceptional performance and value of the Atomic Aquatics Z3.
