[updated 5/6/17] Picking out the Best Scuba Diving regulator for yourself is a very personal diving choice to make. And just like any diving gear choice, it is important that you have a well-guided opinion to make it through. There is no denying the fact that scuba regulators are quite expensive to purchase, particularly, if you are just a recreational scuba diver. These regardless, it may yet be one of the most complex member of your diving kit. Being that, I think you should know how it works.

Other than just allowing you as the scuba diver to breathe underwater, the regulator does a more non-obvious job. This is to transport high-pressure air from the diving tank to your lungs at breathable pressure, so you are not overwhelmed with too much air.

Furnished with the knowledge that the diving device performs this tremendous job, how would you like to have yours so that you can be assured that everything perfect? There goes one reason why you may like to make guided purchasing choice for this scuba kit.

Nonetheless, another obvious reason is the fact that getting to understand your scuba gear is pertinent to doing well when diving under water. Now, you have another reason why you will be better to know the scuba regulator options that are available before opting to purchase one.

Allow me to take you on a review journey to explore a few things to consider when making a decision on which diving regulator to acquire.

GETTING TO KNOW YOUR SCUBA DIVING REGULATOR SET

It is quite obvious that the scuba regulator helps to regulate air to your lungs, but it also works in more technical ways than that. Here is what it does besides:

First Stage

i) at the first level, it reduces air that comes from the diving tank with requisite pressure down to intermediate

Second Stage

ii) at the second level, the regulated air (intermediate pressure) is directed into a hose that feeds it into the regulator’s second level which ensures that it is at a safe enough pressure for you to breathe it in.

All these may somehow be technical for you, so I will just get down to explaining in details, key factors to consider when choosing the best scuba regulator for yourself.

Water Condition

The choice of getting a scuba diving regulator may well depend on the kind of water temperature you intend to dive in. This condition serves as a key factor in enhancing or affecting your in-water breathing encounter.

If you will be diving in cold water, it is important that you get a sealed regulator. This is vital because, at low temperature, the water may get frozen at the first level hence blocking air flow.

For warm water scuba dive, an unsealed regulator will do just fine because it doesn’t have to worry about frozen air on the first level.

First Stage (Diaphragm or Piston)

Here, there is not so much to worry about when it comes to making a choice as both the piston or diaphragm structures are good in themselves.

Just so you know, the first level of the Diaphragm construct has rubber model that contains more springs which help the valves operate well between the two compartments. The diaphragm though works better in cold water conditions.

The piston, however, has less moving parts. This results in a simpler design and more supercharged performance making them more reliable for your scuba diving.

First Stage (Balanced or Unbalanced)

The choice of using a balanced or unbalanced first degree regulator may as well be rested fully on whether you are scuba diving for recreation as an entry diver or a pro.

The balanced one, having a constant supply of air to the scuba diver regardless of the air in the tank, is best for pro scuba divers because of its efficiency.

On the other hand, the unbalanced first level is well fitted for new entrants partly because it becomes harder to breathe when you go deeper or when there is less air in the tank.

Attachment Valve Type

The difference between this two first level attachment valve types is in the way they are attached to the reservoir.

A DIN (Deutsche Industrie Norm) has its thread post screwed into the tank valve; here there is no need for additional braces behind the scuba tank valve.

The Yoke or A-Clamp has its screw located on the opposite end making the oblong metal brace to encircle the tank valve when fitted in place.

Thus far, you have been given the requisite knowledge needed to make the best choice of a scuba regulator. Now, allow me to walk you through the list of best diving regulators that we have painstakingly reviewed and compiled for you.

BEST REGULATOR CHOICE / PICK FOR YOU

  1. Sherwood SR2

1st Stage Type: Pneumatically Balanced Flow-Thru Piston

2nd Stage Type: Pneumatically Balanced Valve

Material: 1st Stage: Marine Grade Chrome Plated Brass. 2nd Stage: Glass-Filled Polyamide

Weight: 4.1 lb.

For all it is worth, one can arguably say that the Sherwood SR2 is one of the few scuba diving regulators that have a well-balanced first stage available today. This is made possible due to the vast improvement that Sherwood enacted on the SR1 to birth the SR2.  Another ingenuity from the SR2 diving regulator is the very versatile way it addresses the problem of pistons that allows dirt and debris to find their way into it.

To tackle that anomaly, Sherwood SR2 is fitted with a hermetic dry spring faucets that obstruct water and dirt from gaining access to the interior of the kit. This way, you have gear that is free of sediments from minerals and ultimately keep your kit at top performance.

In some scuba diving regulators, they are designed to use different adjustment mechanisms for setting the opening effort and ensuring high flow performance. With the SR2 however, you have a one-blow approach that solves that case. Based on its pneumatically balanced second stage, it has a unique single adjustment point that concurrently oversees the opening effort and high flow performance. With this, the dual band issue is resolved.

Guaranteeing easier use for scuba divers, the SR2 has a well-optimized control knob that is easy to locate and operate even for divers who have gloves on. Its second stage is also well shaped and sized such that it is weightless in water.  Scuba regulators don’t get any better than this.

One cannot overemphasize the need for all-round convenience and flexibility for scuba divers when they are under water. To achieve that much leisure, much is dependent on the grade and quality of the gear you are fitted with. In line with this, Atomic Aquatics T3 has prided itself as a pioneer in the use of titanium metal for fabricating its regulator.

Two factors are outstanding with titanium-based gears. Firstly, they are extremely light-weight and secondly, they are entirely non-corrosive in ocean waters. That is getting two for the price of one.

It is not just the titanium metal body that is the best side of the T3. Considering that it is designed with Flow-Thru pistons and also has a sealed system in the piston that is self-lubricated makes it exerts low friction and requires minimal maintenance. Isn’t that just about all that one will expect of a top-class diving regulator gear?

Finally, the T3 is shielded from freeze so you don’t have to worry about the water freezing up and causing frozen water that may hamper the air flow to your lungs. With the same shielded feature, Atomic Aquatic has made the T3 proof to debris and sand finding their way into the system. In a nutshell, you have a highly balanced and efficient system set in the T3.

Weight: 3.1 lb.

How would you define assurance in a scuba regulator? Well, don’t bother trying to explain it. Poseidon Cyklon has these figures to do the definition for you: over 45 years of service to pros and beginners scuba divers and everyone in-between; it has also been the first choice brand for the German Navy. If these two factors do not yet pitch the Cyklon as a tested and trusted scuba regulator to you, I don’t know what will.

The German Navy didn’t just make it their first choice scuba regulator for nothing. The diaphragm at the first stage has its membrane conveying the required pressure to the internal mechanism. By so doing, you have a gear that is internally sealed from the free particles and bodies that are flowing in the water around you. These free bodies like sand, chlorine, salt and other acids, can erode your regulator and cause substantial damage if they gain entrance into it.

For its second stage, the downstream valve design is fabricated with anti-corrosive brass, chromed brass, and stainless steel. All of these to give you an impeccably standardized supply of air that is not tainted by any shortcoming.

For mechanical details about this choice device, Cyklon uses NITRIL O-Rings and is EN250 suitable for cold water conditions.

  1. Cressi T10 – SC Master Balanced

 scuba diving regulator

1st Stage Type: Balanced Diaphragm

2nd Stage Type: Pneumatically Balanced

Material: First-Stage: Chrome Plated Brass, Stainless Steel, and Plastic. Second-Stage: Housing Techno-Polymer, Chrome Plated Brass, Stainless Steel

Weight: 4.8 lb.

The 1st stage T10 – SC is identical to model T10, but with a special chamber that is sealed. This sealing helps to completely isolate the diaphragm and spring from getting into contact with water. This makes it very ideal for diving in waters that are rich in suspension and mineral salts, for archaeological work, potholing and diving in cold waters. The total exclusion of water from the device’s interior including the spring chamber means that no ice can form inside during cold water dives.

The balanced diaphragm first stage is inherently environmentally sealed. The benefit of this type of first stage design is that none of the delicate internal parts is exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

By any means, you can comfortably trust that the Cressi T10 will give you the best scuba diving experience attainable without any glitch or issues.
