Edgetech Towfish Depressors

These Depressor Wings, which are available from Unique Group, allows the Tow Fish to be towed at greater depths and at faster speeds without increasing the length of tow cable in the water. Depressor Wings are available for fitment above 4125 and 4200/5 Towfish, and exerts a downward force on the tow fish as it moves through the water, pushing it deeper.

The angle of the wing is user adjustable to 0°, 5° and 10° depending on the desired dive angle. Optionally available trim tabs on the back of the wing can be adjusted for fine-tuning its performance, and a safety cable is attached to prevent loss of the wing should it become snagged.

It should be noted that the use of a depressor not only increases the tension on the cable but also affects the way the towfish reacts to a change of speed at the helm. Depressors should only be used by experienced operators of sidescan systems.
