The ROV II is the most popular Polatrak probe. Rugged and simple, with the flexibility to interface to most ROV’s or be diver deployed. The probe has replaceable and interchangeable elements, contact tip, nose and tail assemblies, for easy field maintenance. The ROV II can be used as a proximity probe or as a contact probe for checking subsea items, pipelines, or just about any immersed metallic structure
