Mike Lewis’s article titled, “Sub-Surface Baits: Methods for Deploying Baits Below the Surface”, praises the efficiency of the Zwing downrigger. Mike Lewis questions ‘just how deep can you get with a downirgger weight?,’ he writes, “The faster you troll with most downrigger systems, the more it planes the cable, and bait, back up toward the surface. This is true with almost all downrigger weights, even those that are shaped like fish or made very thin to cut water resistance. The exception to this is a hydrodynamically designed wing that takes the place of the heavy lead ‘cannon ball.’ Called the Z-Wing 500, this lightweight weight device works so well that there is virtually no planing of the bait back toward the surface.”
