FIFISH W6 - Long Tether Package
QYSEAThe FIFISH W6 Long Tether Package is an industrial-grade ROV manufactured by QYSEA Technology, rated to 350 m depth and supplied with a 305 m tether reel. It is a human-piloted (teleoperated) system with significant autonomy-assist features — including station lock, altitude hold, collision avoidance, auto path planning, and one-click return — but the primary task (underwater inspection, survey, or manipulation) is performed by a human operator driving the ROV via controller and app. Several extracted facts relate to other QYSEA products (V6 PLUS, V-EVO, W6 NAVI) or third-party research on tethered robot path planning, which are noted but do not alter the core characterization of the W6 Long Tether Package. No independent user reviews or teardowns were present in the source set; all substantive product claims derive from vendor/commerce sources.

Evidence-graded claims from the QYSEA deep report
QYSEA's post-sale warranty requires shipping units back to China, and user support has been described as slow and marginal.
An independent Reddit ROV community thread [15] directly reports China-return warranty requirements and slow/marginal support as user experiences, constituting third-party evidence; however, the sample size is limited and may not reflect all customer experiences.
from QYSEA deep report →
QYSEA ROVs cover an operational depth range of 0–500 meters across the product lineup, with individual models varying (e.g., V6 PLUS at 150m).
Depth ratings are stated on official and third-party commerce pages [5][6][7][8] but have not been independently verified through third-party testing or regulatory certification documented in the dossier.
from QYSEA deep report →QYSEA's sensor and tool suite includes 4K high-frame-rate cameras, 3D laser measurement, DVL, sonar, ultrasonic testing (UT), sampling tools, and 2D/3D seafloor mapping.
These capabilities are described across official and commerce sources [1][5][6][8] for various models, but no independent benchmark, field test report, or customer validation of measurement accuracy or reliability appears in the dossier.
from QYSEA deep report →QYSEA demonstrated 5G wireless long-distance ROV control capability.
The 5G control capability is reported solely via a company news announcement [14] with no independent journalist, regulator, or customer corroboration of the demonstration's scope, range, or operational readiness.
from QYSEA deep report →QYSEA holds 150 global patents.
The 150-patent figure is self-reported via official/commerce sources [1][9] with no independent patent database verification, regulatory filing, or third-party audit cited in the dossier.
