Which FIFISH ROV models are compatible with this tether? Can it be used with other brands?
This spool is basically compatible with all FIFISH ROV models, including the FIFISH V-EVO, V6 EXPERT, and E-GO. It is designed specifically for the communication protocols and connector types of QYSEA products and is not compatible with other ROV brands.
Is the tether fragile? How much pulling force can it withstand?
High-Strength Material: The tether is reinforced with a high-density Kevlar fiber.
Tensile Strength: It can sustainably withstand a pulling force of approximately 100kgf. This is strong enough to safely tow a fully-loaded ROV back to the surface in an emergency.
How do I choose the right tether length (100m vs. 200m vs. 300m)?
Selecting the correct length depends on your operational depth and the distance from your deployment point:
100m (328ft): Ideal for recreational diving, swimming pool inspections, and shallow dock or hull surveys.
200m (656ft): The professional standard for most inland waterways. Suitable for river, reservoir, and coastal search-and-recovery operations.
300m (984ft): Professional engineering grade. Required for deep-water dam inspections, long-distance internal pipe surveys, and offshore wind farm foundation checks.
What are the lengths of the connectors on both ends?
Underwater Section (Main Tether): 200 meters (656 feet). This is the high-strength, Kevlar-reinforced cable that connects the ROV to the spool.
Surface Section (Connecting to Remote Controller): 3 meters (9.84 feet). This is the cable that connects the spool to your remote controller, allowing the pilot to maintain a comfortable distance from the spool during operation.
Why does the ROV require a Tether Spool instead of a wireless connection?
This solves the "underwater radio black hole" problem. Because radio waves do not travel well through water, a physical tether is the only way to support the high bandwidth required for 4K HD real-time video transmission while providing a physical safety line for equipment recovery.
