Power, speed and maneuverability for the most adverse situations.

Based on the well-known and proven Commander MK III, this Observation/Light Work Class ROV has been designed keeping the field operativity in mind. In this model, Mariscope prioritizes function (Form follows function) by focusing on a structure that allows the buoyancy to be varied at any time and the payload of the equipment to be adjusted.

ROV speed and maneuverability, along with pilot training and skill, are in many operations the limiting factors in logistics efficiency after improving travel efficiency through the use of fast boats and reduced dead times.

The characteristics of this ROV reduce its hydrodynamic resistance and improve its maneuverability in all kind of situations. Thus, it achieves excellent performance in all conditions reducing travel and inspection underwater times.

Flat, fast, deep going, compact and light. 6 thrusters and completely modular and interchangeable. Unbeaten in its category.
