depressor wing for deep water towing.
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.
The DDW-1 is constructed of corrosion proof PVC, urethane, and
stainless steel for many years of trouble free operation. The DDW-1
is covered by a full TWO YEAR
WARRANTY.
