What are the best regulators for Scuba Diving? What regulators are rated highly but are still reasonably economical? What is the best scuba diving regulator for my type of diving? These may be some of the many questions you think about when looking into a new regulator for scuba diving. 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 key differences include how easy it is to breath under a variety of conditions and depths, does the regulator stay dry under a variety of conditions and positions and finally how comfortable is the regulator in different diving positions.

ScubaPro MK2 EVO R195

Best Regulators (Steven W Smeltzer)

SCUBAPRO MK2EVO 195

The first of the best regulators under $500 is the ScubaPro MK2 EVO/R195. It is the perfect go-anywhere reg for divers looking for simplicity and reliability at a price that won’t bust the budget.

The MK2 EVO comes with the patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort — regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the previous MK2 first stage. Key Features include:

  • Chrome-plated brass body is 3.5mm smaller than its predecessor but houses an oversized piston by 1.6mm that provides better breat ing performance by increasing airflow by 15 percent.
  • Stainless steel removable orifice allows for easier maintenance while extending regulator life.
  • Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • Meets new EN250-2014 standards for cold-water breathing performance.
  • Weight: INT 232 (oz/g): 24.9oz/706g; /DIN 300 (oz/g): 16.0oz/454g.
  • Airflow at 2900psi/200bar (l/m/SCFM): 3000/106.
  • Intermediate pressure (psi/bar): 123-142/8.5-9.8.

R195 Second Stage:

  • Classic downstream valve comes with a VIVA switch to control free flows.
  • Metal valve housing is built rugged and increases overall reliability.
  • Super-flow hose features larger inner diameter to increase airflow.
  • Reversible hose attachment makes it easy to use on deco tanks.
  • Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
  • Weight: 7.0oz/198g.
  • Airflow at 2900psi/200bar: 1400 l/min – 50 SCFM.
  • Maximum low pressure: 203psi/14bar.

Scubapro introduced the MK2 first stage back in 1963, and it has earned a reputation for smooth performance and the reliability of an anvil. The latest EVO version has a smaller body and larger piston for more-sensitive response, and it is also rated for cold water. The second stage is based upon a design that was created more than 20 years ago. However, nothing about this regulator’s performance is out of date. In ANSTI tests it was rated excellent at recreational depth, and very good throughout the range of depths and breathing rates. The MK2 EVO/R195 also won ScubaLab’s Best Buy for 2015.

Aqua Lung Core Supreme

Best Regulators (Steven W Smeltzer)

AQUALUNG Core Supreme

The last of the best regulators under $500 is the Aqua Lung Core. This new mid-range regulator from Aqua Lung is available in two versions. The regular Core version and the Core Supreme. The Core Supreme is rated for use in water 50 degrees below zero and comes with an environmentally sealed first stage. Otherwise the two versions appeared identical. The CORE regulator’s amazing breathing, which is rated as “superior” on the ANSTI breathing machine, coupled with its generous features, at an attractive mid-range price, provides one of the best values of any regulator offered today. The CORE comes standard with Aqua Lung’s unique, patented, auto-closure device (ACD) which seals water out.

Like the other regulators in this price range, the Cores’ only user control is a Venturi lever which is well positioned and easy to grip with or without gloves. The Venture is good for blocking free-flows although having the markings “MIN” and “MAX” on the top of the second stage would make them more visible. According to ScubaLab, they are the only regulators under $500.00 to be rated excellent throughout the range-of-breathing rates and depths. The Aqua Lung Core/Core Supreme regulators were ScubaLabs Testers Choice for regulators under $500. Key features include:

  • Auto Closure Device (ACD) – keeps corrosive water out of the first stage inlet by automatically closing as the CORE is removed from the cylinder valve
    • This prevents internal lubrication from washing away
    • Safer for elevated percentages of oxygen
  • The balanced diaphragm first stage provides superior, consistent performance
  • The pneumatically-balanced second stage results in smooth, easy breathing
  • Available in yoke (3300 psi / 232 bar max) or din (4350 psi / 300 bar max)
  • The T-shape of the first stage optimizes the location of the 4 MP ports and 2 HP ports
  • Uses parts that are common to other Aqua Lung models for easier servicing
  • The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth
  • A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water
  • Compatible with EAN 40 new, out of the box
  • Equipped with Aqua Lung’s patented Comfo-bite™ mouthpiece along with a reusable mouthpiece clamp
  • The Supreme cold water version is resistant to freezing when diving in waters colder than 50°F / 10°C
  • The Supreme version is equipped with an environmental dry chamber on the first stage and a lip shield on the second stage.

Best Regulators (Steven W Smeltzer)

SEAC DX200

Over the past 40+ years, SEAC has built a strong reputation relying on quality, innovation and cutting-edge designs. The DX 200 series is a good combination for those who want maximum performance, as well as a lightweight, versatile and reliable second stage. The lightweight balanced-diaphragm first stage provides reliable performance even at great depths and low tank pressures. This ultra-high performance 1st stage has been manufactured using “Luxury Technology” to make it remarkably resistant to abrasion.

The new DX200 is easy to breath and provides a wide range of adjustment. The Venturi control is well marked, easy to operate and effective at blocking free-flows. The DX200’s purge cover is a large and allows good control. A gentle push on one of the corners provides an easy clearing of the reg without an overly strong blast. The glossy purge cover and satin-finish metal surrounding it give the reg a refined appearance. The DX200 is rated very good across the board at all test depths.

Cressi Master T10 SC

Best Regulators (Steven W Smeltzer)

CRESSI Master T10 SC

The Cressi T10-SC delivers performance, ergonomic reliability, and ease of maintenance making this regulator a product for true diving professionals. Instructors, guides, dive operators, and researchers will all find a regulator that can meet their needs.

The first stage stands out from the range of Cressi balanced diaphragm regulators because the mechanism is arranged on an axis perpendicular to the axis of air entry, creating a “T” shape. The advantages of this design includes better arrangement of the hoses and less space occupied. The regulator is remarkably easy to inspect and access the mechanism to improve maintenance and calibration operations. The T10 Master uses a larger, high-efficiency conical filter. 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.

The SC designation on this model of the new T10 stands for “sealed chamber,” signifying the environmentally sealed diaphragm first stage that’s rated for cold water. The T10’s second stage has a wide, elliptical diaphragm with a titanium trim piece around the purge and a large, knurled, metallic breathing-adjustment knob. All that metalwork gives it a somewhat beefy look, but test divers found that the second stage is actually quite lightweight and easy on the jaw. 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. In ANSTI testing, the Cressi T10-SC received excellent scores for ease of breathing at all depths and breathing rates. Editor’s pick from SportDiver.

Key features:

  • Weight: 32.7 oz (927 g)
  • Lightweight Jacketed 3/8″ Threaded Low Pressure (LP) Hose
  • First Stage: Cressi T10-SC

Zeagle F8

Zeagle’s new flagship regulator leverages the company’s heritage (“F8” is a nod to the long-running Flathead regulator series), but with a different look and feel oriented as much toward comfort as performance.

ZEAGLE F8

The F8 1st stage has a dry-sealed spring chamber (to stop freezing at water temperatures below 40 degrees F). 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. It is very low in profile, barely extending above the tank valve, and places the low pressure hoses directly out to the sides, in a pattern preferred by many divers.

The second stage is compact and light, with smooth edges and soft parts. 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 on any of the regulators featured here. Where the sprocket-like heat sink connects to the second stage, fingers are protected from scrapes by the wide, soft hose cover. Divers noticed this attention to ergonomics, and that earned the F8 top ergonomic scores by ScubaLabs. The Zeagle F8 was also rated as the Best Buy among regulators over $500 by ScubaLabs.

Key features:

  • Balanced diaphragm design and the environmentally sealed ambient chamber ensure top performance in any condition.
  • Redesigned environmental seal cap and yoke knob enhance ergonomics & design aesthetics.
  • Percision machined neoflon seat harder more reliable material, keeping you diving longer.
  • New inhalation diaphragm provides superior tear strength and improved response time to breathing (super soft silicone molded over a low friction disk).
  • Improved exhaust valve ensures dryness and a lower exhalation effort.
  • Seat-saving orifice, compliments of Atomic Aquatics, retracts when not in use – extending the life of the breathing tube seat.
  • Seat comprised of soft silicone molded over a metal insert to deliver the firmness required for an airtight seal while maintaining the necessary elasticity to prevent leaking.
  • Redesigned front cover and inhalation effort control knob use co-molded components that provide the necessary grip, soft touch and ease of use. Available in several color kits
  • Zirconium-plated inlet tube and heat sink for superior corrosion resistance.
  • Redesigned heat sink dramatically increases surface area, aiding in the heat exchange necessary to avoid freeze-up.
  • Co-molded silicone mouthpiece for better fit and less jaw fatigue

Mares Fusion 52X

Mares calls this “a radical departure” from other regulators. The Mares Fusion 52X Regulator is comprised of the compact top performer MR52X First Stage with the radical Fusion 52X second stage. The Fusion 52X second stage incorporates a double DFC system that provides a consistent flow of air at any depth, even when breathing simultaneously from both the primary second stage and the octopus. The natural convection channel (NCC) system and the design of the Abyss Second Stage with more metal on the front cover, allows this combination to achieve very high performance in cold water. The NCC System increases cold water performance by creating a flow of water across the regulator. The flow is driven by the change of density in water with temperature.

Best Regulators

Mares Fusion 52X

The all satin chrome plated marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

The Fusion’s unique design elements include the long, curved air-bypass tube to the mouthpiece, a purge cover that’s 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. Performance in ANSTI testing was impressive, with the Fusion 52X recording one of the lowest work-of-breathing ratings.

Key features:

  • Hose: 3/8″ Thread High Flow Superflex 29.5″ (75 cm)
  • Weight: 40.95oz (1,161g)
  • First Stage Features:
  • Balanced Diaphragm
  • Double DFC System
  • Natural Convection Channel (NCC) System
  • NCC System Increases Cold Water Performance
  • Pre-Oriented Pressure Ports
  • Material: Satin Chrome Plated Marine Brass
