JW Fishers DDW-1 Deep Dive Wing is a low cost depressor wing designed to tow instrument packages at deeper depths. Operating on the principle of hydrodynamic depression rather than just weight, depressor wings overcome the limitations of conventional downrigger systems. The DDW-1 Deep Dive Wing provides a stable platform for towing instrument packages to greater depths with less cable being deployed.

The design of DDW-1 creates a significant downward force that overcomes drag and pulls the tow cable downward as the wing moves through the water. The "dive angle" is determined by the position of the tow point on the wing which is operator adjustable. Larger instrument packages have more drag and require a greater dive angle. Changing the tow point allows different size instrument packages to be towed to the required depth.

The DDW-1 can be used to tow instruments such as side scan sonar's, towed video systems, marine magnetometers, and towed underwater metal detectors. The DDW-1 can tow magnetometers because it does not have ferrous metals in it's construction and therefore has no magnetic signature. The wing can also tow custom underwater housings containing specialized instruments.
