DELTA 4
EVEN WITH THE BEST-LAID DIVE PLANS
There are times you encounter conditions beyond your control. Sometimes you’re
caught down current, and face a long surface swim working hard all the way. Or
maybe you went deeper than you planned. This highly responsive design provides
a high volume of airflow with even the slightest inhalation effort, making it seem
nearly effortless to breathe at any depth.
• Diver adjustable inhalation effort
• Patented Dynamic Adjustment automatically
maintains inhalation effort throughout the dive
• Adjustable Venturi Switch (A.V.S.) for simple
Dive/Pre-Dive Adjustment
• Stainless steel inline ball swivel reduces jaw fatigue
• Patented orthodontic mouthpiece with high-density bite tabs
