Designed by MarineNav and manufactured on-site, the Oceanus thruster guard minimizes potential damage when foreign debris becomes entangled in the ROV thruster propellers. The thruster guard is constructed from marine-grade materials and is designed to fit over the thruster assembly without affecting propeller motion and is locked in place by four threaded bolts and fasteners. Installation is simple, requiring a minimum of tools and time.
Compatible with Pro and Ultimate class series ROV systems, the Oceanus ROV Gaff Pole is indispensable when retrieving ghost gear, lost mooring chain or underwater cable.

Measure metal thickness even through coatings with ultrasonic metal thickness gauges. The probe does not need to touch the surface under test, as the metal thickness gauge captures reading measurements through 5 mm (0.2 inches) of water. Metal thickness probe orientation does not influence gauge readings. Contact MarineNav for more Information >
Underwater searches and surveys often require precise positioning of the ROV to be known so that observations can be geo-referenced on future dive missions. MarineNav supports several acoustic and tether-based position-tracking systems.
