This polycarbonate add-on fairing is used on the BlueROV2 Heavy configuration to protect the added Subsea Buoyancy Foam and maintain a sleek, hydrodynamic design. Comes with 2 screws that attach to the existing holes in the standard BlueROV2 fairing. Please note that this product doesn’t do much when used alone – it’s meant to be added to BlueROV2 with existing fairings.
