Z-Wing
Over 6 years in the development, the Z-WING's state-of-art design creates significant downward force which overcomes drag, allowing a constant depth to be maintained over a wide range of trolling speeds. Barry Moore, President of Nekton Corp., whose love of fishing and engineering talents, developed the concept of the Z-WING. Barry's many years of experience developing large towing vehicles for underwater research taught him a few things about maintaining depth and lateral location with minimal drag.
The Z-WING is a lightweight, 13" x 7" piece of virtually indestructible
polypropylene plastic. No more heavy lead balls rolling around the boat or swinging off the end of downrigger booms which can cause damage to both angler and boat alike.
The Z-WING has three positions With the center hole being the most
efficient. Attaching the Z-WING 250 by the center hole will produce a 16 degree downward angle far outperforming a 5 lb. lead ball. The Z-WING will hold this angle and lateral position at speeds from under 1 knot to over 6 knots.
SIMPLE TO UNDERSTAND DOWNRIGGING STATISTICS

Knowing the exact Depth and Lateral Location of a Subsurface bait or lure is critical in making the presentation most effective. Simple calculations of tow cord length, based on varying angles of decent, take the guess work out of downrigger fishing. Consult the chart below to understand the relationship between the angle of decent and the length of tow cord needed to attain the desired depth.

Based on the above factors and the varying angles of decent, one can calculate the exact amount of tow cord necessary to reach the desired depth by performing the following exercise. Please be sure to calculate the free board of your boat in to the equation.
Desired depth / factor ( associated with angle of decent ) = Tow cord length
For example: Desired depth = 75 feet and we have a 20 degree angle of decent.
75 / .94 = 79.8 feet of tow cord
At a 30 degree angle of decent the formula would look like this:
75 / .87 = 86.25 feet of tow cord
A steeper angle of decent allows for less tow cord to attain the same desired depth. Since the Z-wing Downrigger will maintain depth and lateral location over a range of speeds, no adjustment in tow cord length is necessary to maintain desired depth.

| LIMITED WARRANTY: The Manufacturer warrants each Z-WING to be free from defects in materials and workmanship for a period of ninety (90) days from the date of original purchase. We will replace any Z-WING that is found to have imperfections in manufacturing if returned to our factory with valid sales receipt or proof of purchase. This warranty does not include damage caused by accidents, misuse, or tampering with the Z-WING. |
