Manipulators et samplers

Subsea Tech has developed its own accessories for Mini-ROV. Among them, a 2-function manipulator that allows grabbing objects, a cutter to cut cables and ropes, as well as water or sediment samplers.


High turbidity does not allow the use of the standard video camera. Acoustic solutions allow imaging even in zero visibility conditions. Scanning sonar makes it possible to scan a zone for navigation purpose, while 2D multibeam sonar, also called “acoustic camera”, is a high-performance real-time imaging solution.

Acoustic positionning

USBL (Ultra-Short Baseline) systems allow location of a target relative to a reference unit on the surface. You can then easily locate and record routing of your Mini-ROV Observer, which facilitates navigation and increases the efficiency of excursions.

Measurement probes

Subsea Tech Mini-ROVs can be equipped with various probes such as: thickness measurement probe, cathodic protection measurement probe or several physico-chemical probes (salinity, conductivity, pH, etc.)

Laser pointer
The combination of Subsea Tech’s laser pointer and Inspection Viewer software is a complete solution for measuring all kinds of distances on images captured by the ROV.
Cable reel

Wind and unwind Mini-ROV umbilical easily with this manual winch fitted with a slip ring.

Wheel frame

If you carry out pipe inspections, the wheel frame helps to contain the risk of friction on the walls.

Image enhancement

Increase the quality of your inspections with the LYYN Hawk Board real-time image enhancement system, integrated directly into the console.
