Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesnt inhibit airflow. It backed that up in ANSTI testing, showing excellent ratings at In partnership with the marine exploration nonprofit OceanX, University of Miami scientists using ROVs discovered the massive brine pools more than a mile deep. But the regs our testers liked best had controls that were easy to use and effective (and well marked). It prompted test-diver comments such as all around comfortable to use and everything you would want in a reg. Our ANSTI testing showed the F8 was giving up nothing in performance for the comfort, and doing it for the lowest price here, making the Zeagle F8 our Best Buy. The purge cover, which takes up the whole front of the reg, is soft and rubbery, the breathing adjustment knob is a full inch in diameter and ringed with soft rubber, and the Venturi lever is one of the easiest to reach and operate weve used (and is clearly marked). This also protects against contamination from particulate matter in silty conditions. Goliath grouper spawning, manatee snorkeling, freshwater springs, shark diving: it's all here, and this is when you can do it. scubadiving.com is part of PADI Media, a division of PADI Worldwide. If you continue to use this site we will assume that you are happy with it. The metal gas tube and precision components of this second stage allow for precision tuning for extremely easy breathing while also retaining heat and moisture from exhaled breath. Where the sprocket-like heat sink connects to the second stage, fingers are protected from scrapes by the wide, soft hose cover. But while the second stage is ambidextrous, the purge is less so. It can bit a bit strong so you will want to be careful as you purge to avoid an unwanted blast of air. I am personally using a ScubaPro MK25/600 and love this regulator. Exotic materials helped keep components light for comfort without sacrificing performance or durability. Breathing adjustments allowed fine-tuning airflow with changes in depth or breathing demands. IT has a large, soft, easy-touch purge cover, and a Venturi switch thats well marked and located on the top of the mouthpiece, where its easy to reach and operate. Second stage features: possibility to regulate both respiratory exertion and the Venturi effect. We conducted these tests at Alexander Springs in Florida with a team of divers who recorded their scores during their dives using underwater slates and waterproof test sheets. Streamlined exhaust tee directs bubbles to the side of face. INT/Yoke fitting only. vibe. The Fusion's unique design elements include the long, curved air-bypass tube to the mouthpiece, a purge cover thats hinged like a trap door, and a rotating air control on the hose fitting that the manual says works like a motorcycle throttle twist forward for less, back for more. The RS790 has a sealed first stage rated for cold-water use in which two of the four low-pressure ports (marked by HFP) are designed to deliver up to a 15 percent increase in airflow. It provides easy breathing in swimming position, dry-air delivery in any position, ease of clearing, and effectiveness of the breathing adjustment thanks to an oversize, grippy knob. Test divers rated it very good for ease of breathing in swimming position, dry-air delivery in any position, ease of clearing, and effectiveness of the breathing adjustment, which divers found easy to dial in thanks to that oversize, grippy knob. Always be sure to give clean, fresh water time to wash away any salt that has accumulated before it can cause corrosion or other damage to sensitive parts such as valves and diaphragms. ScubaLab put these regs through two tests the first is conducted on a breathing simulator (objective), and the second by our team of test divers (ergonomic).

Explore the colors, wildlife and formations found in these unique environments. The marine brass metal body is protected on the surface by a special treatment called PVD (Physical Vapor Deposition), which compared to traditional chrome coatings is exceptionally resilient to the mechanical and chemical wear caused by dives. This new mid-range regulator from Aqua Lung is available in two versions. You can see how each reg performed on the breathing simulator in the charts that accompany the reviews. The cool finish and metal diaphragm cover give it a tough, all-business look. On the ANSTI machine, the XS Compacts performance was rated very good at max recreational depth and good down to our test limits. The next graph shows the same reg at 181 feet and a breathing rate of 30 breaths per minute. The DX200s purge cover is a large, rounded triangle that allows good control a gentle push on one of the corners provides an easy clearing of the reg without an overly strong blast although some divers thought it required more movement than it should have. The F8 1st stage has a dry-sealed spring chamber (to stop freezing at water temperatures below 40 degrees F). The second stage is light enough to be quite comfortable in the mouth and has a purge cover that is soft and large enough that its easy to reach and operate. Test divers found the Venturi lever well marked, effective and easy to operate, even though its small and tucked in out of the way. The small and lightweight 2nd stage help reduce jaw fatigue and in-water drag. The Zeagle F8 was also rated as the Best Buy among regulators over $500 by ScubaLabs. 7 Bubble interference in vertical/stationary position Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures. 11 Comfort of mouthpiece Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/572. Nylon fiberglass design features SCUBAPROs largest second stage casing and diaphragm. In its latest EVO incarnation, a smaller body houses a larger piston for more-sensitive response, and its rated for cold water. diving scuba ALL RIGHTS RESERVED. $957.00 Buy NowReturn to Scuba Diving Best Regulators Reviews List*I try to update the prices regularly, but please check links in case prices have changed or for any special offers. Located opposite the hose and angled toward the back, it can only be easily pressed with the hand on that side, and a careless jab will kick of a blast of air that some test divers found too forceful (though a benefit of the design is it wont free-flow in a strong current or on a fast scooter.) All rights reserved. The reg is novel enough that test divers found that it took a bit of getting used to. This site uses Akismet to reduce spam. The cool finish and metal diaphragm cover give it a tough, all-business look. scores at recreational depth, and delivering air effectively even at a Second stage material: technopolymers, elastomers, with components in metal and cover with Luxury Technology treatment for abrasion and scratch resistance. All delicate parts of the 1st stage including the main spring are sealed behind the clear hydrostatic diaphragm away from the effects of salt or other contaminants in the water, making it environmentally sealed. The simulator pressurizes the test chamber to simulate depths of 132 fsw, 165 fsw and 198 fsw. The exhaust ports on the MX100 are quite short and curve in along the bottom, which helps make the second stage very compact and light but also seemed to allow a little extra bubble interference noted by some divers when vertical, although it wasnt noticeable when in a swimming position. The loops go clockwise, starting at the right, as inhalation begins, and moving to the left, where exhalation starts. Likewise the purge: It feels odd at first, but with a little use, youre able to use it very precisely. The MK25EVO is a balanced piston first stage, Scubapros absolute top performer. With more than three full turns of adjustment, changes made a big difference, allowing test divers to dial in performance and helping the DX200 earn a very good score for ease of breathing and effectiveness of adjustment. The regs we tested in this price range showed slightly higher performance overall on the breathing simulator than their thriftier brethren (principally at greater depths and extreme breathing rates). I have been taking photos of our Underwater world in Europe, Africa, South America, North America and Asia and I want to share those images and experiences with others. These may be some of the many questions you think about when looking into a new regulator for scuba diving. The glossy purge cover and satin-finish metal surrounding it give the reg a refined appearance. Key features include: Over the past 40+ years, SEAC has built a strong reputation relying on quality, innovation and cutting-edge designs. While theres only about 18 of a turn in the Venturi lever, the settings proved just right, with surface free-flows curtailed and easy breathing at depth. Airflow at 2900psi/200bar: 1400 l/min 50 SCFM. None we tested in this price category had breathing resistance adjustments, rotating first stages, swivel hose connections, titanium goodies, etc. The flow is driven by the change of density in water with temperature. 1 Ease of breathing in swimming position Each breath by the machine moves 2.5 liters of air through the regulator, at breathing rates of 15, 25 and 30 breaths a minute. In our ratings, a score of 1=3j/l or greater; 2 = 2.26-3.0 j/l; 3 = 1.51-2.25 j/l; 4 = 1.1-1.50 j/l; and 5=1j/l or less. Super-flow hose features an oversized bore (larger inside hose diameter). Zeagles new flagship reg links to the companys heritage (F8 is a nod to the long-running Flathead reg series), but with a different look and feel oriented as much toward comfort as performance. Divers noticed this attention to ergonomics, and that earned the F8 top ergonomic scores by ScubaLabs. One of the most extreme environments on the planet, such oxygen-less pools may hold the keys to important medical breakthroughs. The SC designation on this model of the new T10 stands for sealed chamber, signifying the environmentally sealed diaphragm first stage thats rated for cold water. breathing. Scavengers eat animals that are already dead instead of hunting live prey. The graphs below show results of ANSTI testing on the same reg at different depths and breathing rates. The top graph was taken at 132 feet at 15 breaths per minute, and recorded a work-of-breathing score of .73 joules per liter excellent performance, showing it was able to deliver air at that rate and depth with little effort. In this edition of Ask a Marine Biologist, Dr. David Shiffman discussed shark feeding behavior. It also made its way onto more divers top-three- favorites lists than any other reg in the test. Below the centerline shows the negative pressure required to inhale; above shows the positive pressure needed to exhale, measured in millibars. regulators effective Venturi and breathing-adjustment controls, and its 7-Ns Ocean Bungalow; diving magnificent, protected reefs; unlimited diving on house reef; gourmet meals; world-class service The good news is that the quality of regulators has improved dramatically over the last several years and there are now a number of high quality regulators to choose from in the marketplace. The Mares Prestige 15X is available in both DIN or A-Clamp (international) fittings and is more than up to the requirements for recreational scuba diving and would make a perfect traveling companion as well as a first time regulator purchase. Key features include: Another of the best regulators is the Tusa RS-790. The nicely finished MX100 has lustrous chrome on the first stage, a braided hose, and an abrasion-resistant finish on the purge cover. Cressi has pulled out all the stops with this new Pro version of the XS Compact, providing a regulator which is ideal for traveling as well as suitable for diving in the coldest waters. If possible, soak your reg while its installed on a tank and pressurized, which will prevent water from getting inside. The lightweight balanced-diaphragm first stage provides reliable performance even at great depths and low tank pressures. At a shockingly low price. Despite the metalwork and large diaphragm housing, the second stage is lighter than it looks, making it surprisingly comfortable. The Prestige does this by way of an angled tube on the right side of the second stage leading to the mouthpiece inlet; its an air by- pass that creates a low-pressure vortex behind the diaphragm. While our test-team divers were impressed with the performance of the $500-and-under regulators, they found that some of the extras that come with these pricier models really are well worth it. Mares calls this a radical departure from other regulators.

So please stop by my website or my blog for more inspiration from around the world and let me know if you have any comments. The second stage is compact and light, with smooth edges and soft parts. 3 Ease of breathing in head-down position In ANSTI testing, the T10 proved one of the top performers in our test, racking up excellent scores for ease of breathing at all depths and breathing rates. Our divers liked regs with a light-weight second stage, an easy, predictable purge, controls that are effective and easy to adjust, and smooth, steady breathing without a lot of noise. With so many different options, models, styles, and types of regulators on the market today, making a, decision can be the most difficult task to undertake. On some regs, the breathing adjustment doesnt seem to make much difference, but the new DX200 isnt one of them. Divers liked the second stages light weight, its braided hose and its purge-cover design, which is effective and easy to use even when wearing gloves. 5 Wetness in head-down and odd positions The cost of quality batteries is a negligible and well-worth what they add to your kit. It can really put a loop on finding the best regulator available for your budget. Five high-flow low pressure ports on a swivel turret maximize hose routing options.
