First Stage Design – Balance vs. Unbalanced
As a new diver diving into the world of scuba, one of the most critical pieces of gear is your regulator. This apparatus delivers the all-important oxygen from your tank to your mouth so you can breathe underwater. When inspecting regulators, the first stage design is one of the most important factors to consider. This mechanism reduces the high-pressure air from your scuba cylinder to an intermediate pressure more suitable for breathing. There are two main types – balanced and unbalanced.
Balanced first stages use a spring-loaded piston to evenly distribute pressure over the diaphragm as tank pressure drops during your dive. This results in consistent intermediate pressure delivery regardless of tank volume. Unbalanced regulators use a flow-through piston design that is less complex but can vary in delivery pressure as your air supply depletes.
For recreational diving, a balanced first stage is often preferred for its reliability and even flow during the entirety of your dive. Models like the Warrior Regulator Max use this balanced design to give divers one less thing to worry about and provide smooth easy breathing at any depth.

Adjustable Intermediate Pressure
One characteristic to look for when researching scuba regulators is an adjustable intermediate pressure setting. This gives you control over the effort level required to inhale through the second stage.
Being able to fine tune the IP can help optimize air delivery for your personal comfort and diving style. I always appreciate regulators like the Warrior Regulator Max that allow me to customize performance.
Adjusting IP Affects Inhalation
The intermediate pressure is the reduced air supply from the first stage that feeds the second stage. Adjusting this pressure affects how lightly or forcefully you must inhale to receive air.
A lower IP requires more inhale effort, while a higher setting allows very easy airflow. I suggest starting around the factory default and adjusting up or down to find your ideal responsive sweet spot.
Conditions May Warrant IP Adjustments
You may also want to alter intermediate pressure based on diving conditions. For example, colder water may warrant an increase to make breathing easier with constricted airways.
Or, when diving to deeper depths, bumping up the IP a bit can counteract the increased water pressure for consistent airflow. Having this flexibility caters to your needs.
Easy Access to the Adjustment Knob is Key
To easily manipulate intermediate pressure, the adjustment knob must be conveniently located. I like when it is prominently positioned on the front of the first stage.
The Warrior Regulator Max features a large, easy-to-grip IP knob. Even wearing thick gloves, you can fine tune performance on the fly while diving.
Consider regulators with adjustable intermediate pressure as it allows you to customize breathing responsiveness. Dialing in that perfect setting keeps you focused on the amazing underwater sights rather than the effort required to inhale.

Second Stage Type – Piston vs. Diaphragm
When researching scuba regulators, understanding the second stage design is key. This is the component that delivers air directly into your mouth with each inhale underwater.
Two common second stage valve types are pistons and diaphragms. Knowing the differences will help select the best system for smooth airflow and reliability.
Piston Valves Use Metal Components
A piston valve utilizes metal parts – typically brass, stainless steel, and chrome – that rise up and down to open and close the air flow through the second stage.
I’ve found piston valves to provide excellent airflow, especially at deeper depths where more intermediate pressure is required. The Warrior Regulator Max uses a piston design.
Diaphragm Valves Rely on Flexible Material
Meanwhile, diaphragm second stages incorporate flexible discs, usually made of rubber or plastic, that flex to deliver air. This negates the need for metal components.
Diaphragms can provide a very smooth breathing feel, but require ultra-clean air to avoid potential sediment buildup that could impede movement over time.
Consider Your Diving Needs and Conditions
When selecting a second stage type, think about your diving environment and needs.
For cold water diving, a piston delivers air powerfully and is less prone to freezing. But for warm, sediment-free conditions, a diaphragm may provide extremely easy draw.
I suggest trying out different second stage types to see what feels best matched to your diving. An ideal regulator mates performance and durability!
Venturi Control for Easy Breathing
One optional but highly useful feature to look for in scuba regulators is a venturi control adjustment. This allows divers to fine tune the airflow responsiveness of the second stage.
Being able to customize the inhalation effort to your exact preference makes breathing easy and helps focus on enjoying your underwater adventure.
How the Venturi Control Works
The venturi adjustment wheel utilizes a vacuum-assist principle to change the ease of inhaling through the second stage regulator.
Turning the control clockwise increases air delivery assistance, providing very easy airflow. Counterclockwise decreases assistance, requiring more inhalation effort.
Match Venturi to Depth and Conditions
One advantage of the venturi control is the ability to adjust breathing effort to match changing depths and dive conditions.
For example, at shallower depths, I dial back the assistance for just the right moderate inhale effort. Then as I descend deeper, I increase venturi assistance to counteract rising ambient water pressure.
Venturi Control Promotes Consistent Airflow
Venturi adjustment also helps maintain consistent airflow as your tank pressure decreases throughout the dive.
By bumping up the assistance as needed, a well-tuned venturi makes breathing easy from the first inhale to the last regardless of tank volume.
The feature-packed Warrior Regulator Max incorporates a venturi control that I absolutely love. It really optimizes my breathing comfort at any depth!
If you want to be able to customize the breathing performance of your regulator, be sure to look for an adjustable venturi control. You’ll breathe easier!
Dive/Pre-Dive Switch to Prevent Freeflows
An important safety feature to look for in scuba regulators is a dive/pre-dive switch that prevents unwanted freeflows.
A freeflow occurs when the second stage inadvertently provides continuous airflow without inhaling, wasting precious air. The dive/pre-dive switch blocks this.
Pre-Dive Mode Cuts Off Airflow
In the pre-dive position, the switch essentially turns off airflow through the second stage. This is used on the surface before descending.
With the air blocked, bumping or moving the regulator won’t trigger a freeflow. I can’t tell you how many times this simple switch has saved my tank pressure topside!
Dive Mode Enables Normal Air Delivery
Once underwater, flipping the switch to the dive position allows normal second stage operation, providing airflow on each inhale.
The dive setting should be visibly indicated so there is no confusion about the mode you are in. An easy transition prevents surprise freeflows.
Quick Access is Key for Switching Modes
Since you’ll be toggling the dive/pre-dive switch frequently, it needs to be prominently positioned for quick access.
Look for regulators like the Warrior Regulator Max that place the switch right on the front of the second stage. Even wearing thick gloves, it’s easy to operate.
Using the dive/pre-dive switch should become second nature before and after each dive. Consider it cheap insurance against freeflows and fast air loss!

Attached to the second stage regulator, the mouthpiece delivers those life-giving breaths of air with each inhale. Having a comfortable design is crucial for extended wear.
Look for regulators equipped with a sizable orthopedic mouthpiece that fits securely while allowing easy airflow when diving.
An Orthopedic Design Prevents Jaw Fatigue
Typically made from durable silicone or rubber, an orthopedic mouthpiece utilizes a wider paddle shape to spread contact over more mouth area.
This prevents the jaw fatigue that can occur when biting down on a small, compact mouthpiece for prolonged periods underwater.
Comfort Allows You to Breathe Easy
A comfortable mouthpiece also enables easy, unimpeded breathing since you aren’t distracted by a cramping jaw or ill-fitting piece.
I suggest trying on regulators at the dive shop and taking a few test breaths to ensure the mouthpiece is a good match for your mouth.
Durability and Hygiene are Also Key
In addition to being comfortable, the ideal scuba mouthpiece withstands frequent use while resisting odors and deterioration.
Quality regulators like the Warrior utilize a double-banded silicone mouthpiece that provides a secure seal and easily cleans after salty dives.
Don’t underestimate the importance of a well-designed mouthpiece. This direct connection to breathing comfort will make or break your diving experience.

Stiff, rigid hoses would significantly hinder your range of motion while diving. That’s why flexible rubber or braided polymer hoses rule the day.
Top regulators like the Warrior Regulator Max utilize lightweight, supple hoses that move freely as you swim through the water.
Reinforced Interiors Resist Damage
Though flexible, the hoses must also remain durable. This is achieved through reinforced interiors that resist crushing hazards.
Quality reinforcement includes stainless steel wire helixes and woven polymer fibers. These strengthen the hose without sacrificing pliability.
Exterior Sheaths Protect from Elements
An exterior sheath provides abrasion resistance and protects the interior reinforcement from corrosion and deterioration.
Tough polyurethane outer sheaths shield the hoses from scrapes, debris damage, and environmental exposure.
When inspecting regulators, take the hoses in hand and manipulate them to test flexibility. Peak performance balances durability and freedom of movement.
Exhaust Tee – Route Away Bubbles
A well-designed regulator will incorporate an exhaust tee that directs your exhaled bubbles out and away from your field of view.
This routing of exhaust keeps bubbles from interfering with your vision and helps maintain optimal underwater clarity.
Exhaust Tee Positioned to the Side
The exhaust tee is a small branch attached to the second stage regulator that catches exhausted bubbles and re-directs them.
Look for the tee positioned to the side of the mouthpiece so exhaled air will be aimed away from your face.
Angle of the Tee Affects Bubble Flow
The angle at which the tee is set also influences the path your bubbles will take. A steep, downward angle will send them straight below you.
A more gradual angle may be preferable to push bubbles off to the side while minimizing downward vision interference.
Try Different Exhaust Tee Styles
Test regulator options that have different exhaust tee configurations. Breathe out while submerged to experience the bubble path of each.
I prefer the prominently-angled exhaust tee on the Warrior Regulator Max as it really sweeps bubbles out of my line of sight.
While a small detail, an optimized exhaust tee contributes tremendously to the overall diving experience and visibility underwater.

Composite Plastics Also Trim Weight
Regulator parts constructed from engineered plastics – such as second stage bodies – also contribute to reduced weight.
Weight-savings add up with composite fiber housings and internal braided hoses. Ounces shed makes a difference through long dives.
Every Ounce Matters Underwater
Speaking of extended dives, even small weight reductions help stamina and reduce fatigue when that energy is needed most.
At just 1.48 pounds, the featherweight Warrior Regulator Max delivers incredible performance without wearing you down.
Keep it light. Less really is more when it comes to the effort required underwater. Prioritize lightweight regulators that won’t be dead weight!
Chrome or PVD Coating – Corrosion Resistance
Exposure to moisture, saltwater, and debris takes a toll on regulator materials. Special coatings greatly improve corrosion resistance and longevity.
Chrome and PVD (physical vapor deposition) finishes provide an extra barrier protecting against the harsh underwater environment.
Chrome Plating Adds Protection
A mirror-finish chrome plating applied to external metal regulator components significantly increases corrosion resistance.
The chrome layer acts as a shield against saltwater oxidation and keeps the base metal pristine through years of dives.
PVD Coatings Offer an Alternative
As an alternative to chrome, PVD coatings provide extreme hardness and durability while maintaining a sleek, low-profile black finish.
PVD (physical vapor deposition) utilizes vaporized metals to leave a thin, impermeable shield preventing corrosion.
Internal Chrome Coatings Also Help
In addition to external chrome or PVD finishes, internal chrome coatings on regulator pistons and springs add longevity.
The Warrior Regulator Max utilizes specialized black PVD and internal chrome to maximize corrosion resistance inside and out.
Be sure to inspect regulators for protective finishes that extend service life. Keep your gear performing optimally dive after dive!
Warranty and Servicing for Peace of Mind
Given the life-support role your regulator plays, strong product backing provides important peace of mind in your purchase.
Look for regulators that come with generous warranties along with included professional servicing to keep your gear performing safely.
Lengthy Warranties Demonstrate Confidence
A robust manufacturer’s warranty covering multiple years reflects confidence in reliability and workmanship.
Many regulators come with lifetime warranties for the original owner. This safety net adds reassurance if defects ever arise.
Included Servicing Extends Life
Opt for regulators that bundle professional servicing with the purchase. This periodic maintenance is essential.
Factory servicing cleans and fine-tunes the regulator to keep it operating like new. The Warrior Regulator Max includes the first service for free.
Routine Servicing Maintains Performance
Be sure to follow the recommended service intervals after each set of dives. This upkeep is the key to longevity and safety.
Investing in regulators backed by strong warranties and servicing gives confidence that your gear will reliably last for years of underwater adventure.
