Thether Lenght: 100 Meters (164ft)

Stay connected and dive with confidence using the QYSEA FiFish Tether Cable, the official communication and power link for the FiFish V6 and V6S underwater drones.
Engineered for extreme durability and zero signal loss, this tether combines strength, precision, and flexibility — keeping your live video feed clear and control response instant, no matter how deep you explore.

Key Features & Benefits:

  • Kevlar-Reinforced Durability:
    The inner copper conductors are wrapped in a Kevlar weave — strong enough to withstand up to 50 kg of tension, ensuring reliable transmission even under current or debris strain.

  • Neutral Buoyancy for Smooth Handling:
    Designed to float naturally in water, the tether reduces drag and eliminates slack, making navigation effortless and stable.

  • Ultra-Stable Signal Transmission:
    Delivers uninterrupted HD video and control data — essential for inspections, filming, and research.

  • Weather & Salt Resistant:
    The marine-grade coating prevents corrosion, fray, and cracking, even after repeated dives in saltwater environments.

  • Plug-and-Play Compatibility:
    Quick-connect ports integrate directly with FiFish tether connectors — no tools, no calibration, just instant connection.

  • Professional-Grade Reliability:
    Trusted by marine surveyors, environmental researchers, and filmmakers worldwide.

Built for explorers and professionals who can’t afford downtime, the FiFish Tether keeps your mission connected — from shallow reefs to deep-sea inspections.
