The SWiFT SVP is a compact sound velocity profiler that is designed for coastal, harbour and inland hydrographic survey, and is ideal for USV (uncrewed surface vessel) use. Outputting high-quality sound velocity, pressure and temperature measurements, it also utilises an integrated GNSS receiver for accurate geo-location of each profile.

Featuring a rugged titanium housing depth-rated to 500 metres, the versatile sensor can run for up to a week on a single charge and allows data to be quickly and easily downloaded via Bluetooth® wireless to Valeport's Windows, iOS or Android software. This data can then be shared immediately in industry-standard data formats via email or cloud services.
