Breathe Better, Dive Deeper: The Mares VAD Regulator Advantage
Posted by Elma Tarr on June 26th, 2025
What is VAD and Why Does It Matter?
Mares’ Vortex Assisted Design (VAD) is a revolutionary technology integrated into the second stage of many of their regulators. Simply put, it optimizes air flow to deliver a natural, effortless breath at any depth, under any conditions.
Unlike traditional designs, the VAD system directs air through a bypass tube that creates a swirling vortex of air inside the second stage. This vortex keeps the diaphragm lifted, ensuring constant, smooth airflow with minimal breathing resistance—even during deep or demanding dives.
Benefits of the VAD System:
- Effortless Breathing: Reduced resistance means less fatigue and more comfort, dive after dive.
- Reliable Performance at Depth: Maintains consistent airflow even when you're exploring deeper waters.
- Dryer Breathing: The vortex minimizes moisture in the mouthpiece, offering a cleaner, drier breath.
- Simple, Durable Design: Fewer moving parts mean better reliability and easy maintenance.
