What is ROVSTAR?

ROVSTAR is a transportable ROV equipped with a magnetic sensor. It can detect metal objects that are buried two meters below the surface. It is also equipped with an AC sensor and fore-monitoring sonar. It is a unique device that is owned only by the company.

What is ROVSTAR?

ROVSTAR is the nickname for our transportable ROV equipped with magnetic sensor.
ROV is short for Remotely Operated Vehicle. It is a robot that is capable of moving underwater by remote control.
Unlike larger ROVs, it does not require a dedicated mother ship, and all its component parts can be loaded onto a four-ton truck for transportation to any area that is accessed by road.
It also features an agility not seen in large ROVs, and is best suited for marine surveys in coastal areas. ROVSTAR is the only transportable ROV equipped with magnetic sensors.

The naming of ROVSTAR

ROVSTAR is also is a pun on Lobster.
Lobsters move in single file when they walk underwater.
And this ROV directly follows the buried objects, in a single line.

Figures in parentheses refer to when the magnetic sensor is provided.
