|
Fishers 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.
Key Features of the DDW-1 :
