FIFISH V6 - Inspection Package
QYSEAThe FIFISH V6 (and its Expert/Plus variants) is a tethered ROV system manufactured by QYSEA Technology, designed for underwater inspection, search and rescue, and light industrial tasks. The base V6 Expert is rated to 100m depth, weighs 3.9 kg, features 6-DOF omnidirectional movement, 4K UHD camera, and up to 6000-lumen LEDs, with pricing from $2,999 to $4,298 depending on configuration. The system includes autonomous stabilization features (station lock, depth lock, posture lock, collision avoidance) but the core inspection task is fundamentally human-driven via tethered teleoperation — a human operator pilots the ROV to perform inspections. Academic research groups (KUCARS, University of Zagreb) have used FIFISH-class ROVs as platforms for experimental autonomous inspection frameworks (AquaChat, AquaChat++), but these are research prototypes validated only in simulation or controlled environments, not the commercial product as sold.

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.

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.
