Underwater Mud Sampler
QYSEA FIFISH Mud Sampler is a high-performance sediment collection tool designed for environmental monitoring, geological research, and industrial inspections. It enables the FIFISH ROV to retrieve intact samples from various underwater floors, including riverbeds, reservoirs, and seabeds. By providing direct access to benthic layers, it is an essential asset for identifying pollutants, analyzing microbial life, and assessing underwater ecosystems.

Frequently Asked Questions
Have questions about our underwater ROVs or your order? We’re here to help!

What is the maximum volume of sediment the Mud Sampler can collect in a single mission?
The Mud Sampler has a maximum capacity of approximately 250 cm³ / 250 mL (8.5 fl oz) per sampling cycle.
Which FIFISH models are compatible with the Underwater Mud Sampler?
The Underwater Mud Sampler is compatible with FIFISH V6 EXPERT and E-GO. Please choose the matched model as the connectors and mounting bracket differ between these two models.
What is the primary function of the Underwater Mud Sampler?
The Underwater Mud Sampler is a specialized tool used to collect sediment, silt, or mud samples from the seafloor or riverbeds for scientific research, environmental monitoring, or geological analysis.
Can I see the sampling process in real-time?
Yes. Through the ROV's camera, you can monitor the sampler, and ensure successful sediment collection via the live FPV feed.
