The Bathy2 is a high-performance bathymetric instrument designed to be interfaced with ROVs, underwater vehicles and drop structures. Delivering density-corrected readings of pressure, as well as outputs of conductivity, temperature and sound velocity, it also offers a dedicated data output for INS.

The versatile sensor features Valeport interchangeable pressure modules to provide optimal performance for specific depth requirements, and also accepts inputs from external pressure sensors for Digiquartz referencing, as well as altimeters.
