FIFISH E-MASTER
QYSEAThe FIFISH E-MASTER is a revolutionary industrial AI underwater robot for high-precision measurements, inspections, and surveys in complex marine environments. It features Q-DVL for stable hovering in currents up to 3 knots, U-INS Plus autonomous navigation, QY-MT smart measurement with 99.7% accuracy, and QY-BT 2D/3D seafloor mapping. Its modular design enables rapid component changes. The robot has a 176° surface view, 146° underwater view, 4K UHD camera, 10,000-lumen lighting, and 10 cm macro focus. Dual hot-swappable batteries provide 150 minutes runtime, with 50-minute charging to 90%.

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.
