Supplier's note

  1. Technical Breakthroughs:

    • SOLAS Compliance: Ensures legal readiness for global maritime operations.
    • Corrosion-Resistant Bronze: Outperforms aluminum-based models in saltwater durability.
    • Adjustable Activation Depth: The Pro Model’s 4–8m range exceeds industry benchmarks by 33%.

  2. Optimal Version Selection:

    • Base Model: Ideal for vessels operating in shallow coastal waters (e.g., fishing boats).
    • Advanced Model: Suitable for offshore platforms requiring depth flexibility and IMO compliance.
    • Pro Model: Best for deep-sea vessels needing extreme durability and USCG certification.

With SOLAS certification, you can ensure regulatory compliance. The Pro Model’s titanium-reinforced bronze offers 50% higher corrosion resistance than standard bronze, making it ideal for prolonged deep-sea use. Pair its expanded depth range with rugged construction to handle extreme marine conditions safely.
