Frequently Asked Questions (FAQ)
1. Q: What is the difference between the S9-3.5H and S9-6H models?
A: Both models feature the same 20-meter (65 ft) max depth and 95 L/min airflow. The difference is battery endurance. The S9-3.5H is lighter and ideal for quick recreational dives, while the S9-6H is designed for extended use, such as professional aquaculture, underwater inspections, or all-day spearfishing.
2. Q: What does “Surface Supplied Diving System” mean?
A: Unlike traditional scuba where you carry air on your back, a surface-supplied system keeps the air source floating on the water. The S9 draws fresh air from the surface unit, meaning you never run out of air—you just return to the surface when the battery depletes.
3. Q: Is the S9 Series safe for beginners?
A: Yes. The S9 is designed with anti-choking and anti-backflow technology. The full-sealed mask prevents seawater from entering the airway. Since there is no heavy tank on your back, it is much easier for adults, ladies, and beginners to maintain balance underwater.
4. Q: How do I recharge the battery? Are there extra costs for air refills?
A: The S9 is fully rechargeable via a standard power outlet (no special chargers needed). There are zero ongoing costs for air refills. This saves you hundreds of dollars compared to traditional scuba diving, where you pay for tank filling every time.
5. Q: Can I use this for shallow water work (Aquaculture/Fishing)?
A: Absolutely. With a 20-meter depth rating, it is perfect for fish farming, underwater salvage, pool maintenance, and spearfishing. The bright orange floats provide high visibility on the surface, ensuring safety during work operations.
6. Q: How long does it take to set up before diving?
A: Setup is instant. The S9 is portable and compact. Simply charge the unit, attach the regulator, place the floating unit on the water, and you are ready to dive in minutes. No heavy tanks to haul or complicated valves to adjust.
