ONE OF THE BEST-PERFORMING
REGULATORS
I have ever used is the Atomic T2. It was designed by Dean Garraffa after he left Scubapro. He and business partner Doug Toth's originally wanted to make the regulator for Scubapro, but the management of that branch of the big US corporation was focused only on the bottom line at the time, and wouldn't countenance it. So Dean and Doug started Atomic Aquatics, and the rest is history.

Atomic's venerable T2 is no more, but taking its place is the more nitrox-friendly T2x. This solid-billet-titanium super breather comes with a factory-sealed first stage and a low-pressure port swivel turret. The second stage even sports titanium Comfort Swivel (which we loved). It also has a seat-saving orifice and uses Atomic's Automatic Flow Control, a depth-activated venturi control. Work of breathing barely changes from a moderate breathing rate at 20 feet to a heavy breathing rate at 200 feet, and in the ocean the T2x provided smooth, dry performance in all swimming positions, along with minimal bubble interference and a powerful purge.

BOTTOM LINE: The T2x is the Rolls Royce of regs, with top-drawer performance, exotic metalwork and lots of cool features.

Atomic T2

THE T2 HIT THE MARKET in May, easily earned a 2005 Testers' Choice in our June review of new regulators, and has had divers talking ever since. In standard breathing simulator tests the T2 delivered a perfect score without breaking a sweat. In the muscle test the reg was able to attain a breathing rate of just under 91 RMV.

Over $500 Tester's Choice

This powerhouse reg (T2) smashed all previous records for low work of breathing on the ANSTI simulator and for in-water performance, collecting more Excellent scores than any regulator we've tested.

If you're a believer in the adage, “You get what you pay for,” then you're going to love the T2 from Atomic Aquatics. This sleek-looking super breather is the Ferrari of regulators, with a price to match—$1,399. But just look at what you get for your money.

In breathing simulator tests, the T2 smoked every RMV/depth category, delivering a perfect score without breaking a sweat. So we turned up the heat. But when we punched in extremely stressful breathing rates and excessive depths, the reg smoked those too. It didn't seem to matter what RMV or depth we threw at it, the T2 continued to breathe like a dream. When we took the T2 into the ocean it repeated this superhero performance, scoring Excellent for ease of breathing regardless of position.

En route to earning a Testers' choice nod in this year's review, the ST1 proved to be the latest in a long line of top-performing regs from Atomic Aquatics. It's loaded with all the performance goodies Atomic regs are famous for, plus adds a couple dollops of comfort by way of a well-designed mouthpiece and Atomic's Comfort Swivel. In the 2007 primary reg review, the ST1 also turned in the lowest work of breathing scores on the ANSTI machine and was named the “smoothest breather of the bunch” by test divers.

Conclusion 
“At the end of five days of exhaustive testing and comparison the test divers had got to know each regulator pretty well. We then spent a day of leisure diving when each one could use the regulator of his own choosing. This revealed true preferences. First choice was clearly the Atomic M1, closely followed by both the Apeks ATX100 and the ATX200 and then, in no particular order the Aqua-Lung Legend LX Supreme, the Scubapro 5600/MK25 and the Mares Abyss.”

…this reg turned in Excellent performance on the breathing simulator, earning perfect work of breathing scores when subjected to our standard reg tests. In the muscle test, it reached a breathing rate of just over 81 RMV. Past and present in-water tests have shown the M1, a 2002 Testers' Choice, to be a real easy breather in all positions. The reg has a very efficient purge system and minimal bubble interference. Test divers liked the mouthpiece and low-pressure port turret on the balanced piston first stage that simplifies hose routing.

Atomic B2/M1/Z2

True to Atomic's claims, the redesigned B2 and M1 did deliver improved work of breathing on the simulator, although this improvement simply puts a shine on what was already stellar breathing performance. The Z2 effortlessly kept pace with its higher-priced brethren.

When the regs were taken out for some real-world diving they proved to be sweet breathers in all positions. Test divers considered the B2, Z2 and M1 to be the driest breathing regs in this year's go-round. The regs come with a two-year/300-dive service interval, and the limited lifetime warranty is not contingent upon annual servicing.

The key to the success of the Atomic brand seems to be not to make things particularly different but to make them better. The B2 is a second-generation design which combines a new second stage that has an all-Titanium mechanism with the previously available B1 chromed brass and 316 stainless-steel first stage. I never found this regulator wanting in the amount it could supply, yet it was discreet and subtle in its delivery. There were no sudden and dramatic rushes of air – it flowed. It was sublime. Added to the fact that it is a jewel in the way it is made, any purchaser is likely to be a proud and long-time owner.

Atomic Aquatic's B2 breathes effortlessly on the simulator, regardless of RMV or depth. But this isn't just a laboratory reg. The B2 earned the highest total score for in-water performance of any reg in any price. It breathes easily in all positions and is the only reg to earn an excellent score for dryness. The B2's dual silicone mouthpiece, introduced last year, is still a favorite among testers.

This 2003 Testers' Choice breathed effortlessly on the simulator, delivering perfect scores on ScubaLab's standard tests. When pushed to its limits, the reg was able to achieve a breathing rate of just a tad over 75 RMV. Take the B2 into the water and it breathes easily in all positions and is dry as a bone.

THE Z2 ONLY RECENTLY hit dive stores, but already it is developing a reputation as a superb breather. When subjected to ScubaLab's standard simulator test protocols, the Z2 delivered perfect simulator scores. When pressed to the limit, it was able to achieve one of the best breathing rates of this group, just over 87 RMV. This superior performance carries into the water as well, where test divers found the reg a very easy and dry breather in all positions with an excellent purge. The Z2 has a new high-flow second stage casing similar to what's on the new T2. Like all Atomic regs, the Z2 also uses Atomic's patented Automatic Flow Control and comes with a great dual composite mouthpiece.

Atomic Z2x

Atomic added its Comfort Swivel to the Z2 and renamed it the Z2x. Its balanced-piston first stage is available with a seven LP port design or a five LP port swivel turret. The second stage's brass valve body is plated with palladium/zirconium for corrosion resistance, while the lever, orifice and second-stage spring are titanium. It comes standard with Automatic Flow Control and a seat-saving orifice. When placed on the breathing machine, the Z2x kept up with the T2x at every RMV/depth level and then did the same in the ocean. Our test divers found very little bubble interference and lots of comfort.

Bottom Line: The performance benefits of the T2x at about a third of what it costs for “the best”.

“I almost forgot I wasn't using my primary” is how one test diver summarized the SS1's performance during our in-water testing. It was the only reg to earn any Excellent ratings from test divers—once for ease of breathing and again for user controls. “The buttons are easy to use even when it's in your mouth,” commented one test diver. On the breathing simulator, the SS1put up work of breathing numbers worthy of a primary regulator, earning Excellent ratings in three of the tests, and a Very Good in the most extreme breathing category—67.5 RMV at 165 feet.

BOTTOM LINE: The SS1 is the top-of-the-line octo-inflator and our 2007 Testers' Choice. It's also the most expensive unit in this review, but worth every penny if you want the ultimate in performance.

The Atomic Aquatics Frameless mask was such a hit that divers were soon asking for a smaller version—and they got it. The new Medium-Fit Frameless uses the same large Ultraclear single lens, surrounded by a soft silicone skirt (black or clear). The only difference is the size of the skirt, about a quarter-inch narrower than the original.

The shape of the Atomic Frameless lens was computer-designed to maximize field of view both side-to-side and vertically, and no mask tested here could beat it. In both the full-sized version and the slightly narrower Medium Fit version, we measured an impressive 85 degrees of horizontal vision and 75 degrees vertical.

BOTTOM LINE: This is our overall favorite frameless mask. It fits great, has a wide field of view, great squeeze-tab buckles, and it folds up flat in a cool low-profile case.

A speed demon on the slalom course, Atomic's SplitFin is pretty fast flat out too. This robust fin's rather stiff, longer-than-average blade doesn't fold up in a power stroke like some other splits do - good for when that eagle ray flaps in out of nowhere and you want to accelerate. For close work, the fin is both nimble and efficient despite its length. A well-shaped foot pocket ensures stability and comfort. We found the SplitFin to offer the best buckle system of all the fins we tested, with a special buckle that slips over a mounting post on the fin. To detach, you simply squeeze both tabs and slip the buckle off the post. To attach, slide it onto the post where it clicks into place. Couldn't be easier!

The first time I tried Atomic Aquatics' SplitFins®, I knew that my ideas about kicking would have to change. These fins ate up distance without hard work. Due to a lack of ankle strain, I felt like I was wearing no fins at all. The most dramatic difference that I noticed was when surface-kicking on my back. My legs felt much lighter on the upbeat and follow-through with the SplitFins® than with paddle fins. I also found that the SplitFins® work best with a short, fast kick as opposed to a long, slow one. It isn't often that a revolutionary product comes along that changes the way we dive. The SplitFin® is one of those products.

While it excels in performance, no other adjustable fin comes close to the scores Atomic earns in fit and comfort. The foot pocket maintains a grip on your foot that virtually eliminates wobble. Even female test divers were able to achieve a good fit.

Kicking out from shore requires power and acceleration and the Atomic SplitFin delivers both. The best buckle system in the business makes it literally a “snap” to put these fins on and take them off when entering the water. And a well-shaped foot pocket ensures stability and comfort.

This impressive new fin gets its name from the smoky transparent panels on its long split blades. They are a bit more flexible than previous versions of the Atomic Splitfin, but still generated the highest thrust measurement of all the fins in this review. The Smoke on the Water fins also tied for the fastest speed score among open-heel fins and slashed through the slalom course with a top-three performance. In ergonomic tests, it was one of only two open-heel fins to earn an Excellent rating from test divers for Acceleration, and it also earned the highest score possible for ease of donning and doffing, thanks to the new spring straps with oversized finger grip. Firm rubber rails produce great power with little effort and provide stability with all kick styles.

TEST DIVER COMMENTS: “The perfect balance of comfort, speed and maneuverability”... “An all-around great fin made better with the spring strap”... “Power and control: What more can you say?”

A 2007 Testers' choice winner for its near-perfect blend of power and agility, this fin not only delivers serious performance, but it looks cool doing so. Named for the smoky transparent panels on its long split blades, the fin burns the competition for sheer speed and acceleration, plus it has no equal when it comes to pegging the thrust meter. Down on the reefs, it's nimble and responsive to minor course corrections, and its firm rubber side rails provide stability with all kicking styles. Uniquely designed spring straps with oversized finger grips make donning and doffing a breeze. Simply put: This is an all-around great fin.

Atomic Liquid Blue SplitFin

This new fin shares the spotlight as this year's best overall fin. Named the Liquid Blue because of its translucent look, this fin is identical in shape to the original Atomic Aquatics SplitFin, but is made of a slightly softer high-performance thermoplastic rubber material. This makes it a little lighter than the original and gives it a bit more snap. That said, the performance of the two fins is nearly identical. The Liquid Blue provides acceleration when it's time to go turbo, but is also very responsive. The Liquid Blue is just as stable as the original SplitFin, and shares the same buckle system. One of three fins rates "very good" for maneuverability.

The magic behind the SV1 snorkel is an additional tube inside the lower breathing tube. This scupper valve allows water washing down the barrel to bypass the mouthpiece without getting inhaled. Below the scupper valve is a regular purge valve, and with every exhalation, any accumulated water is expelled. A flared top maximizes airflow, and down below, a rotating mouthpiece can be easily positioned for a perfect fit. MSRP $55.
