Interspiro Divator Full Face Mask Review: The Safest, Easiest-Breathing PSD Full Face Mask We’ve Used
Public safety diving isn’t recreational diving. It’s task-loaded, low visibility, often cold, and frequently performed in environments where contamination risk is a serious concern. In those conditions, your full face mask isn’t “gear”—it’s a life-support system.
In this review, we’ll cover why the Interspiro Divator Full Face Mask has become one of the most trusted full face mask platforms in public safety diving—and why we believe it delivers best-in-class breathing performance with major safety advantages, especially when configured with positive (safety) pressure.
Sink or Swim Scuba is one of only three Interspiro distributors in the United States, supporting dive teams, dealers, and technicians nationwide.
The Big Differentiator: Breathing Performance (By a Large Margin)
Most full face masks on the market are functional—but many breathe poorly, especially under workload. Public safety divers don’t need “acceptable.” They need a breathing system that performs like a top-tier, high-performance regulator.
The Divator breathing valve is one of the best-tested breathing valves available, designed to maintain extremely low breathing resistance at all depths, even if secondary pressure varies. That matters when divers are working hard, in current, or in cold water.
In our experience, the Divator’s breathing performance isn’t just “good for a full face mask”—it’s in the same category as other high-performing premium regulators, which is rare in the full face mask world.
Extreme Conditions: Mud, Oil, Cold Current—Still Performs
Operational environments are messy. The Divator system is designed to keep performing even when conditions are not ideal. Mud, oil, and fast-flowing cold current don’t have a serious impact on performance the way they can with lesser systems.
A one-way valve in the inhalation channel helps prevent water from entering the valve mechanism—reducing freeze risk and preventing sticking issues in cold water environments.
Positive (Safety) Pressure: Leaks Air Out, Not Contaminants In
One of the most important PSD features is safety (positive) pressure.
Here’s the practical reality:
-
With positive pressure, the mask tends to leak air outward (you may notice bubbles).
-
That outward flow helps reduce the risk of water or contaminants leaking inward at the seal.
For teams operating in questionable or contaminated water, this is a major safety advantage. If you’re building a program around contamination control and operational risk reduction, positive pressure is a serious tool.
Natural Rubber vs. Silicone: Why Rubber Wins for PSD
The Divator mask is available in silicone or natural rubber. For many public safety teams, natural rubber is the better operational choice because it:
-
is excellent for decontamination
-
tends to avoid the same contaminant absorption concerns that some teams worry about with other materials
-
holds up well in hard-use environments
If your team routinely dives in environments where decon procedures matter, natural rubber is worth prioritizing.
Low Volume Visor + Inner Mask Design: Reduced “Dead Space” and CO₂ Re-Inhalation
Divator’s low volume visor reduces buoyancy from trapped air, and the inner mask design minimizes “dead space,” helping reduce CO₂ re-inhalation. That means:
-
better breathing efficiency
-
less fatigue during longer, task-loaded dives
The purge button makes it easy to drain water quickly if needed.
Communications Ready (And Designed to Help Clarity)
Public safety teams often require communications—especially for coordinated search patterns, evidence recovery, or complex scenes. Divator is prepared for underwater comms, and the airflow design helps reduce turbulence noise that can interfere with communication clarity.
It’s also designed to accept spectacle inserts for divers who need corrective lenses.
One Real-World Challenge: Too Many Options Can Be Hard to Navigate
The Divator platform has many configuration options—breathing valves, pressure types, materials, comms setups, accessories, and more. That flexibility is a strength, but it can also be difficult to maneuver if you’re trying to spec the right setup quickly.
If you’ve ever looked at Divator options and thought, “Which version is right for our team?”—you’re not alone. The solution is simple: match configuration to mission profile and environment, and standardize where possible.
Maintenance Value: Cost Savings Over a Yearly Cycle
Public safety equipment cost isn’t just purchase price. It’s ownership cost: service cycles, downtime, parts availability, and ease of standardization.
In many team setups, there can be real cost savings over a yearly maintenance cycle—especially when teams standardize platforms, streamline parts, and reduce “mystery mix” equipment issues. (Exact savings vary by usage, configuration, and service scheduling.)
Works Extremely Well with the DP1 Surface Supplied System
The Divator is also a strong match for surface supply operations—especially when paired with the Interspiro Divator DP1 Surface Supply System. For teams exploring surface supply:
-
Divator + DP1 creates a high-control, mission-ready system
-
supports comms integration
-
supports long, task-loaded work cycles
If your team is moving toward surface supply, this combination deserves a serious look.
Bottom Line: Safest and Easiest-Breathing Full Face Mask on the Market
If your team wants:
-
the easiest breathing full face mask system available
-
positive pressure protection that leaks air outward vs. pulling water in
-
natural rubber options that support robust decontamination procedures
-
a system that performs like a premium regulator under workload
-
strong compatibility with surface supply (DP1)
…the Interspiro Divator Full Face Mask belongs at the top of your list.
Sink or Swim Scuba is the only authorized Interspiro distributor for NC/SC and supports dealers, technicians, and teams.
