It is a superb regulator for both warm and cold water that stands out for its great build quality, top-notch design, and smooth breathing experience. It also comes with a swivel port which we loved!
It ticks all the boxes you could want in a recreational regulator but the price will make it too expensive for most. That said, you get what you pay for and whether you are looking for a lightweight travel option or a cold-water reg that should take a beating, the TFX has it all.
The Atomic Aquatics TFX is our favorite high-end regulator and absolutely worth it for seasoned scuba divers.

The Cressi XS Compact AC2 follows Cressi’s long-standing tradition of building quality gear that wins in terms of price-value ratio. It’s a beginner-friendly all-rounder mainly built for beginners and warm-water enthusiasts. Breathing is smooth, consistent, and effortless even down to 30-35m / 90-110ft although we wouldn’t recommend it for any technical diving adventures.
A drawback is that it’s relatively heavy and not balanced, but that’s to be expected at this price range.
What we liked a lot was that it’s absolutely foolproof which is great if you’re just starting out: Just plug it in and dive! If you’re looking for an inexpensive scuba regulator that will get you started after your course, the Cressi XS Compact AC2 is a great choice.

Atomic Aquatics T25 Limited Edition
We earn a commission if you make a purchase, at no additional cost to you.
Crafted with an exclusive titanium alloy and featuring the coolest coating in the industry, the Atomic Aquatics T25 Limited Edition wins our design award by a large margin. Beyond its sleek and polished appearance, the regulators offers an amazing underwater experience with smooth airflow and intuitive controls. While it comes with a premium price tag, its advanced features like Automatic Flow Control and environmental sealing make it an investment worth considering for the passionate diver. Even more so if you love the brand and want to show that off.
A drawback to the amazing look is that it’s rather prone to scratching on boat decks, pool floors, etc. The titanium material also makes it unsuitable for Nitrox over 40% (which is still more than enough for recreational diving).
The Atomic Aquatics T25 Limited Edition is the most beautiful scuba regulator we have ever used. If you can afford the massive price tag, you can be sure that you stand out among all the other divers in your group.
Apeks XTX50
We earn a commission if you make a purchase, at no additional cost to you.
The Apeks XTX50 is our top choice for sidemount diving due to its excellent hose routing and rotating swivel port. Paired with extreme durability and the fact that you will easily find replacement parts anywhere you go makes it an amazing regulator also for recreational divers. Its core is actually identical to the Apeks XTX200 with the same specs and ratings (which makes it our top choice in 2025.
What makes the Apeks XTX50 stand out (and qualifies it as one of our primary regulators personally) is the rotating swivel and extra 5th port which makes it the best sidemount and technical scuba regulator on the market.
That’s besides all the other features like being totally indestructible, cold water ready, breathing like a charm, etc. Get the Apeks XTX50 if you want one of the best regulators on the market at a very acceptable price.

Aqualung’s Leg3nd Elite scuba regulator is a masterpiece in the world of scuba regulators and an optimal choice for those diving in cold water. With its sleek design and a plethora of advanced features, it makes diving with it a joy. It comes with an over-balanced diaphragm, a pneumatically balanced second stage, and adjustable controls. We really liked the Auto Closure Device (ACD) which makes sure your first stage cannot flood when it isn’t connected to a cylinder.
All these features make it the best choice if you like diving in cold water, even under ice, but make the entire kit bulky and large. If you like the rugged look, it’s an amazing piece of technology, however.

Another entry into Oceanic’s reliable line of dive gear, the Oceanic Delta 5 eDX scuba regulator has carved a niche for itself with its stellar performance and affordability. Its contemporary design (loving the silver finish) is matched by a host of features like the adjustable Venturi switch and an environmental seal while not breaking the bank.
It features an over-balanced diaphragm in the 1st stage, but getting replacement parts is a bit tricky. Oceanic also recalled its so-called dry valve technology (DVT) after some quality issues.

Out of all the dive gear we review, we always love eco-friendly options the most, and the Apeks Ocea scuba regulator is one of our favorite pieces so far. It is the first environmentally-conscious regulator made from recycled materials and bio-plastics, manufactured in a solar-powered facility. We already were Apeks Fangirls and boys, but this new rendition of the proven XL4+ cements their position as a super innovative scuba brand.
It delivers the usual high-class we have become accustomed to from Apeks, including great cold water performance, over-balanced diaphragm design, environmentally sealed 1st stage, lots of ports, and multiple color options!
The Apeks Ocea is our top eco-friendly regulator option and also wins the prize for “most innovative”. It comes at a price, however, and as with all innovations we cannot know the longevity of new materials, but it’s well worth the money!
Other Scuba Regulators We Have Reviewed
Besides our 10 top choices from above, we have also reviewed and tested a lot of other scuba regulators.
HOG D3
We earn a commission if you make a purchase, at no additional cost to you.
HOG makes some of the best “budget” scuba gear on the market and has long left the “secret champ” status. Their equipment is rock-solid, built extremely well, and will last you for years.
Their prices are very competitive, especially if you are from North America. The only drawback I see with HOG equipment is that replacement parts are hard to come by in other parts of the world.
If you are willing to bring your own small spare parts kit on a dive vacation, the HOG D3 is a super well-made piece of equipment for any beginner.
It looks cool, works in any environment, and will last forever. What’s not to love?
The HOG D3 is one of my favorite regulator sets out there.
Atomic Aquatics T3
We earn a commission if you make a purchase, at no additional cost to you.
If money really is not an obstacle…and you want an ultra-smooth breathing experience while reef diving…then the Atomic Aquatics T3 is the one.
This is not a Tesla or Mercedes…it’s a scuba regulator Lamborghini. It’s outrageously expensive but so worth it.
From the looks to the feel, the packaging, the materials, and the breathing…it’s flawless.
What is a scuba regulator?
A scuba regulator allows a scuba diver to breathe from a scuba tank underwater. The first stage of the regulator lowers the tank pressure of 200 bar to medium pressure between 7-15 bar, while the second stage releases ambient pressure that is ready to breathe in.
The scuba regulator is the central piece of your dive equipment that helps us breathe underwater from our scuba tank.
The first scuba regulator was built by famous explorer and scuba diver Jacques Yves Couteau who called it “aqualung”.
It looked different from today’s regulators, however, the underlying working principle was the same.
The parts of a scuba regulator
Every scuba regulator consists of at least a so-called first stage, a medium-pressure hose, and a second stage with a mouthpiece.
In addition, we need a submersible pressure gauge to indicate the current tank pressure, as well as an inflator hose for our BCD.
Let’s look at all the pieces that make up a scuba diving regulator kit individually:
First stage
The first stage is essentially a pressure regulator (hence the word “regulator”) which is screwed into the tank valve and lowers the pressure from tank pressure (200 bar max) to medium pressure (7-15 bar).
All first stages feature several high and medium-pressure (HP) outlets through which we connect the other parts of our regulator setup to the tank.
DIN vs INT valve
Just like scuba tanks, regulators either feature a DIN or INT valve.
The easiest approach is to just pick the one that’s more common in the area you plan on diving in the most. In Europe or North Africa, for example, this is DIN, while INT is prevalent in North America and most parts of Asia.
Don’t worry about it too much though. There are plenty of adaptors from DIN to INT and vice versa.
Medium-pressure hose
The medium-pressure hose connects the first stage through a medium-pressure outlet with the second stage and the mouthpiece.
Medium pressure is around 7-15 bar, depending on the regulator.
Second stage
The second stage is usually what most people have in mind when thinking about a scuba regulator, with its iconic mouthpiece and front-button design.
The job of the second stage is to lower the medium pressure from the hose to ambient (surrounding) pressure at each depth and provide us with air by breathing from the mouthpiece.
The purge button allows us to depressurize the entire regulator once we disconnect the first stage from the tank.
Octopus
The Octopus is a second medium-pressure hose and second stage used as a backup and for emergencies. It often has a different color than the main one, usually yellow or similar, but otherwise works identically.
Submersible pressure gauge (SPG)
The submersible pressure gauge or SPG indicates the current tank pressure and is connected to the first stage through one of the high-pressure outlets.
Inflator hose
The inflator hose aids us in inflating our BCD with medium pressure coming from the first stage.
BCDs usually ship with their own inflator hoses, so if you buy a BCD, you don’t need to get one when buying your regulator.
Warm water vs Cold water
Cold water is defined as anything below 15°C and requires special cold water diving equipment.
Only scuba regulators with a DIN250A certificate may be used for cold water diving. You will also need a second first stage in order to dive with double-valve tanks that are also required.
Such regulators are a little more expensive, however, they’re much safer than freezing regulators and voiding your dive insurance policy.
Tips for buying a scuba regulator
Now that we have looked at what scuba regulators do, and what they consist of, let me give you a few more tips for buying your own
Pick a cold water diving regulator
Even if you never dive under ice or in lakes at home, I recommend going for a cold water-certified regulator.
They are usually very well made, not a lot more expensive than their warm water siblings, and allow you much more flexibility if you do choose to dive at colder dive spots.
Choose a DIN valve
DIN is much safer and more convenient than Yoke/INT regulators by definition.
If you are unsure what to use, pick a DIN valve and get an extra adaptor to connect it to INT or Yoke valves if necessary.
Unless you live in an area where INT is the type of valve available, of course. In that case, pick that.
Replacement parts available
This is important, especially for those in rural areas or regularly diving at exotic places.
Get a regulator that is well known and for which replacement parts are readily available. Apeks, Aqualung, or ScubaPro are well known around the world, whereas most dive bases do not have parts for Atomic Aquatics, for example.
Don’t fall for hype
Go for what works for you and not for anyone else (including me).
Marketing is great and all, but look if you really need the marketed features or whether they even make sense…Looking at you here, integrated mouthpiece/inflator hose combo…
Set a budget
By any means, if money is not a limiting factor, go and buy that titanium regulator with diamond encasing now! However, it’s always a good idea to set a fixed budget +-a little buffer and stop yourself from looking at pricing tiers that are beyond your scope.
You do you
I personally have a great distaste for Poseidon regulators, for example. They are built like tanks and always work, however, they are really really uncomfortable, and releasing water from them is a pain.
If they are exactly what you want though, don’t be put off and go for it. You are the one who needs to dive with it and will feel much better if you select something you are 100% convinced of.
