Proven stable towed bodies for every purpose. Whether you need a custom design or one of our standard tow fish designs, Specialty Devices Inc. has the right towed body for your application. Our tow fish are the result of many years of research, design, and field testing. 

 

 All towed bodies are scale tested before construction to ensure high stability and low drag. An active dynamic stabilization system is available for use in doppler current meter tow fish, or to stabilize your swath depth sounder. (Contact us for remote depth, pitch, or heading control.) 

 

Many features for easy transport and on-deck storage have been incorporated into standard designs. We custom build tow cables, and offer our "Fairwrap" cable faring for quiet towing without strumming. Made in the USA
