Compact size, manually placed
The overall equipment is lightweight and does not require lifting devices. It can be manually laid by small ships, greatly reducing the threshold for operation

Shield anti trawl cover is a small anti trawl structure designed by our company for the needs of nearshore terrain measurement, tide level observation, and fixed-point temperature and salinity depth measurement. This device can be equipped with sensors such as tide gauges and CTD for near bottom measurement. With its low and streamlined design, it effectively prevents damage to monitoring equipment caused by bottom trawling vessels, providing reliable protection for long-term observation in shallow water areas.

The overall equipment is lightweight and does not require lifting devices. It can be manually laid by small ships, greatly reducing the threshold for operation
The overall height is less than half a meter, closely attached to the seabed, effectively avoiding the hooking and dragging of trawl fishing gear
Reserve sufficient length of ropes internally to meet the deployment requirements under a maximum water depth of 70 meters
Made of materials resistant to seawater corrosion, it can resist long-term erosion from the marine environment

Deploy tide gauges and other equipment in shallow water areas for tide level observation to improve equipment safety and data continuity
Deploy sensors such as bottom temperature and salinity depth gauges (CTD) to achieve fixed-point hydrological data collection
