OPTIONS AND ACCESSORIES
Let your mini-ROV get smarter! With so many options and accessories, your Guardian will become an indispensable tool for all your underwater observation and inspection tasks.
Manipulators and Samplers
Subsea Tech has developed its own accessories for the Mini-ROV. Among them, a 2-function manipulator that allows to capture objects, a cutter for cutting cables and ropes, as well as water or sediment samplers.
Sonars
High blur does not allow the use of standard video cameras. Acoustic solutions allow feedback even in conditions of zero visibility. Sonar scanning makes it possible to scan an area for navigation purposes, while 2D multi-beam sonar, also called an "acoustic camera", is a high-performance real-time imaging solution.
Acoustic Positioning
USBL systems allow a target to be located relative to a reference unit on the surface. You can easily find and save the route of your Mini-ROV Guardian, which simplifies navigation and improves the efficiency of trips.
Measuring Probes
The Subsea Tech Mini-ROV can be equipped with a variety of probes, such as a thickness probe, a cathodic protection probe, or several physico-chemical probes (salinity, conductivity, pH,…).

The combination of Subsea Tech's laser pointer and Inspection Viewer software is a complete solution for measuring any distance in images captured by the ROV.
Easily wrap and loosen the Mini-ROV umbilical cord with this manual winch with slip ring.
If you do pipe inspections, the wheel frame helps keep the risk of rubbing against the walls.
Improve the quality of your reviews with the LYYN Hawk Board real-time image enhancement system integrated directly into the console.
