Tow Fish

The Tow Fish is a towed underwater depressor made by Dartmouth Ocean Technology. The Tow Fish allows users tow one or many hydrophones at a constant depth behind a vessel at a constant depth.  The tip of the Tow Fish is weighted so it shields the hydrophone sensor, reducing flow noise.

Use Tow Fish to conduct underwater research and marine mammal monitoring. The Tow Fish minimizes drag and maintains even depth improving the accuracy of your data collection. Tow Fish is the perfect tool for deploying towed arrays and maintaining regulatory compliance while performing seismic surveying or marine construction.
