Best Scuba Diving Regulators & Reviews in 2021
Scuba diving is an amazing activity that allows you to explore the underwater world. It is also a sport that requires a lot of preparation before you dive into the water.
You need to ensure that you have the right equipment to enjoy scuba diving safely. The first thing you need to consider is the regulator. A scuba diving regulator is a device that helps you breathe while underwater.
There are different types of regulators depending on the type of diving you want to do. For instance, if you are planning to dive in open water, then you should use a drysuit regulator. If you plan to dive in a pool, then you should use an air tank regulator.
How Do We Conduct This Scuba Regulator Reviews
Our divers gave their scores on a variety of factors, offered comments, and picked their favorites.
We use two different testing methods when reviewing dive equipment. The first method involves using a simulated diving environment called the Breathing Machine. This allows us to accurately measure how well each piece of equipment works under controlled conditions.
We also take these same pieces underwater where they are used by real-world divers. In both cases, we evaluate performance based on three key criteria: ease of operation, reliability, and comfort.

SEAC MX100 INT 230 bar, Octopus and Diving Regulator Set, Bag Included
Since we last tested the MX100 we’d have some changes in the internal lining which improve Stability-of-Air.
Divers had described it as well as very good because its airflow eased and dry and very comfortable in swim position but noted an increase in effort and water penetration during face-up and head-down position.
Testers feel the reg was relatively resellable to free-flow but some of it was a critic of their tiny, harder-to-find venturi control.
Another sore spot was the mouthpiece whose long tappings made smallmouth uncomfortable.
On the light second stage, the score was satisfactory for comfort and the noise score was good.
The diaphragm – the first set is compact but balancing in its environmental seals.
Sherwood Oasis Pro
Oasis Pro was the highest-rated reg of his class. It was rated for dryness and silence almost as great as it was excellent.
Divers of the tests found him extremely quiet, giving him the only high score for sound.
The diaphragm seal is somewhere between supple and stiff, which is very resistant to the flutter even by strong currents.
The first piston consists of the first two high pressure and four-low pressure ports in the first four high pressure and a low pressure port respectively.
The reg was extremely resistant to free flow even if we were trying to blow it was questioned by some testers whether venturi was needed.
The unit was silent when some testers questioned whether venturi was necessary.
Seac DX 200 ICE
ICE DX 200 uses balanced diaphragms on the initial stage cast of brass with a polished chrome finish.
Two of the four low pressure outlets are inclined at 20 degrees while the rest extends to 30 degrees to give extra flexibility in the routing of hoses.
The two-stage balanced airflow filtration is controlled by venturi and regulates air leakage pressure.
It is equipped with anti-ice panels inside which prevent the cold air to penetrate and a stainless-steel adjustable valve seat provides convenience at maintenance intervals.
There are controls with Venturi that help to prevent the free movement of water from the internal air.
Mares Rover 15X
Mares Rover 15X Regulator with Free Special Upgraded Dual Octo
The Mares Rovers come in two variants – identical second stages with different first steps.
The Rv2S is the preferred rental regulator of many European diving schools. 2 high pressure and 4 low pressure pre-orientation ports allow a flexible hose configuration.
It offers safety and air circulation control with a mesh grid of two stages also. Coldwater kits can be purchased separately and put into place by an authorized technician.

Cressi AC2 Compact
This combo brings Cressi’s latest balanced-piston first stage to a seasoned member of its second-stage family.
The device had excellent performances on the simulator and scored a very good score across the board for easy breathing and ‘dry air’ in positions.
But what brought it out was comfort thanks to the thin profile and lightweight of the second stage.
The piece fit in someone’s hand,” the tester said. The top Venturi Control is readily accessible and operates although there wasn’t a leak problem in the regulation even during diving.
Some divers noted additional noises and bubbles interference.
Aqua Lung Leg3nd Elite
On a reg over $500 – legs 3RD Elite is our test selection. These include deeper Heat-exchangers and radial openings in the cover. It is rated excellent for dry air in normal or standing positions. A favorite for diving test divers. The best performance in both the water and simulator. It’s the only regulator to obtain very good scores as far as breathing effort in the conventional position the head up and in straight lines to take place. It also took very good scores for comfort and noise while others called it soft” and very “effortless“. Its breathing adjustments were rated very good for efficacy.

The S620 Ti is smaller and lighter but reinforced and uses the same diaphragm, decreasing the task of breathing effort by 37%.
Hog D1X Sealed Yoke Classic 2.0
HOG D1X Classic 2.0 Sealed Regulator - Yoke or Din w/Free DDF Slap Strap (Din)
On the simulator, the D1X gave its sluggishest breath in a range. The second stage of the reg is not the smallest here however they are light compared to their size.
This large adjustable breather knob has no large range of motion. The result was pronounced in the effort of breathing, to the point where some people felt Reg if twisted open in such wide-open circles.
The balanced diaphragm initial stage contains two large pressure ports and a rotation turret with 5 low-pressure ports.
The D1x is among several favorite tests. It won for comfort as much as for bubble interference.
Mares Abyss 52X
The abyss 52x comes equipped with two metal stage combines most of what is available on Rovers.

Mares 28XR – HR
XR – this new Reg as expected is a tec related design.
There are four low pressure ports and there is a fifth one on the vertical wing and a central valve connection. It was in pristine in-water condition and proved excellent.
The purge is soft and predictable and the reg cleared easily cleanly and taking one high clearance score.
The breathing adjustment was rated primarily good for its efficiency though some large-mittened divers found the switch small. The second step is small and lighter than metalwork suggest.
Atomic Aquatics Z2
An improved corrosion resistance is made up of a zircodone plated brass structure of the regulator.
The balanced second stage features automatic flow control as part of the balanced piston system.
Two HP and seven low pressure ports exceed many regulators since the LP ports are connected to a fixed cap rather than a swaggling body.
The second stage’s titanium seat saver orifice reduces wear on the valves seat after repeated use extending maintenance for the regulator up to 2 years for 300 dives. Z2 stands for Zir.

Before Buying a Scuba Diving Regulators
The second part of our review process includes taking your new gear out for a day at sea or lake. We will put it through its paces with some basic tasks like swimming, snorkeling, spearfishing, etc.
This gives us a good idea about what kind of problems might arise during actual dives. You can expect to see things such as leaks, clogs, poor flow rates, low pressure settings, etc.
If any issues occur, we’ll let you know so you can make adjustments accordingly.
What Makes One Scuba Regulators Better Than Another?
When choosing between various models of regulators, there are several factors that come into play. These include size, weight, price, durability, features, quality control, warranty, etc.
Size refers to the length and diameter. Weight refers to the total amount of material required to build the product. Durability means how long the item lasts without breaking down. Features refer to the number of functions available within the unit. Quality Control ensures that all products meet industry standards. The warranty covers repairs or replacements after normal wear and tear.
Here are some other important points to keep in mind when buying a regulator:
- Size matters! Smaller units tend to be more portable but may not provide enough volume to support deep dives. Larger units offer greater capacity but require larger tanks.
- Price varies greatly from model to model. Some manufacturers charge hundreds of dollars per unit whereas others sell them for less than $100.
- Check the manufacturer’s website for information regarding warranties and return policies. Most companies allow returns only if defective items were shipped back directly from their warehouse.
- Make sure the regulator has been tested thoroughly prior to purchase. Many online retailers don’t perform this step which could result in purchasing something that doesn’t work properly.
Things To Know When Buying a Scuba Regulator Online
Online shopping offers many advantages over traditional brick-and-mortar stores. One advantage is convenience because you no longer have to drive around town looking for the perfect fit. Another benefit is cost savings since most websites offer free shipping.
However, there are drawbacks too. First off, you must trust the company selling the goods. There are plenty of scams out there that try to steal money from unsuspecting customers. Also, you never really get to touch or examine the merchandise until you’ve made payment.
Another drawback is that you’re limited to whatever selection the retailer provides. Unless you buy direct from the manufacturer, you won’t find anything else besides what was offered initially.
So, if you decide to shop online, here are some tips to help you avoid getting ripped off:
- Read customer feedback carefully. Look for positive comments and complaints posted by previous buyers. They’ll give you insight into whether the seller treats his/her customers fairly. If they complain about poor service, it might mean that your order will take much longer to arrive.
- Ask questions before making an order. You should know exactly what you want before placing an order. For example, do you need a regulator with a mouthpiece or just a tank valve? Do you prefer a manual or automatic regulator? What type of hose does the regulator use? Is the regulator compatible with your current equipment? How big is the tank? Does the regulator have a built-in gauge? Are any accessories included?
- Be wary of sales gimmicks like “free” upgrades. Don’t fall victim to these types of deals where you pay extra for little value. It’s best to stick with standard options unless you see a clear reason why you’d want to upgrade.
- Shop at reputable sites. Avoid ordering from unknown sellers who claim to ship quickly and cheaply.
Should You Buy a Yoke or DIN Regulator?
There are two types of regulators available today – the “Yoke” style and the “DIN” style. Both work well but they do differ slightly in their construction.
A yoke-style regulator has a single handle that controls both the flow rate and pressure settings. This means that if you adjust the setting too high, you could potentially damage the valve itself.
A DIN style regulator uses separate handles for the flow rate and pressure adjustments. Retailers don’t perform this safety check which could result in purchasing a product that doesn’t function correctly.
The main difference between the two styles is how easy it is to change the air supply line when using either one. The DIN style requires more effort than the yoke style as you have to remove the entire regulator assembly first. However, once removed, changing the air source is easier.
If you plan on diving regularly, then buying a DIN-style regulator makes sense. Otherwise, go ahead and purchase a yoke-style regulator.
Do you need an environmentally sealed regulator?
The sealing system in the environment is additional space around the first stage that is filled with silicone oils or another non-freezing liquid. The mechanism stops freeflow and helps prevent the rotating parts of the regulator from freezing under 0 degrees F.
However, environmentally sealed regulator models would be considerably more costly if they are purchased as well as serviced. An environmentally sealed regulator is only important if you’re likely to use it regularly to dive into the cold sea.
The add-on bonus is that it prevents any saltwater or debris from escaping at the time of use minimizing maintenance concerns but it is more costly to get or maintain. Environment Seals are more expensive.
Balanced or Unbalanced
For warm waters and for the more adventurous people, the primary differentiation between a balanced and unbalanced regulator is its ventilation process This term refers to a change in airflow when you’re low on oxygen.
A balanced regulator allows you to give an airflow to each breath to emptied tanks. With tank pressure dropping an unbalance regulator will supply lower airflow with less pressure. A new sensation may indicate that you might not get enough fresh air when this shift occurred.
If you’re diving under cold conditions or exceed the recreational limit (40 meters), use a balance regulator. During intense immersion, it could be unsafe to change the airflow.
The Bottom Line
This article has covered the extensive of different best scuba regulators, and now it’s up to you to choose which type is right for your diving needs. We hope we have provided enough information so that you can make an informed decision about what regulator will work best for you!
