ULTRA CLEAR HGG Glass™

SEASOFT's ULTRA CLEAR HGG Glass™ is manufactured with very low iron content to reduce the green tint commonly visible in traditional glass. Reducing these impurities helps decrease unwanted reflection and allows more available light to pass through the lens.

This can be particularly beneficial during night diving, low-light conditions, and dives where underwater visibility is already limited.

Crystal ARC™ Anti-Reflective Coatings

Crystal ARC™ refers to multiple microscopically thin metal-oxide coatings applied to the lens to reduce reflected light. By allowing more available light to pass through the glass, the coatings are designed to improve clarity and contrast underwater.

SEASOFT states that a conventional mask using standard float glass may transmit approximately 84% of available light, while the Super Mask lens system can transmit up to approximately 98%.

SEA DIAL™ Mask Strap

The current Delta Force Super Mask configuration includes the SEASOFT SEA DIAL™ Mask Strap. This replaces the older neoprene clamshell-style strap previously supplied with the mask.

• Dial Adjustment: Tightens the strap in small increments for precise tension control.
• Quick Loosening: Reverse the dial to release tension.
• Wide Rear Support: Provides a broad contact area against the head or dive hood.
• Non-Slip Design: Helps keep the strap positioned securely during use.
• Even Tension: Helps reduce uneven pulling that can contribute to discomfort or mask leakage.

Fit & Comfort

The Delta Force Super Mask uses SEASOFT's FITZ™ full liquid crystal silicone design with a flared skirt intended to provide a comfortable, watertight seal. The manufacturer identifies the mask as best suited for medium-large through extra-large face shapes.

As with any dive mask, facial shape is as important as overall size. Test the mask seal before use to confirm proper fit.

Initial Lens Preparation

SEASOFT states that the Delta Force Super Mask and its lenses require proper preparation before the first dive. Follow the manufacturer's current preparation instructions before using the mask underwater. Avoid cleaning or preparation methods that are not recommended for the ULTRA CLEAR HGG Glass™ and Crystal ARC™ lens coatings.

Care & Maintenance

Rinse the mask thoroughly with fresh water after each dive and allow it to dry completely before storage. Keep the lens, silicone skirt, SEA DIAL™ strap, and adjustment mechanism free from salt, sand, and debris. Store the mask in the included soft case when not in use and follow SEASOFT's current care instructions for the coated lens system.

Expert Insight

The Delta Force Super Mask is particularly well suited for divers who prioritize optical clarity and a comfortable fit on larger face profiles. The current addition of the SEA DIAL™ strap is a meaningful upgrade because it provides finer tension adjustment and more even support than a conventional strap, while the ULTRA CLEAR HGG Glass™ and Crystal ARC™ coatings are designed to maximize available light in challenging underwater conditions.
