The lures in all Mepps Killer Kits have been carefully selected, using the principles of Mepps Color Technology, to catch fish under a wide variety of fishing conditions. In addition, most of these kits are "programmed", and feature proven lures for a specific species of fish. This makes it very easy to select the right lures for just about any kind of fishing. Whether you fish for trout, panfish, bass, pike, walleye, or trophy bustin' musky, there is a Mepps programmed Killer Kit perfect for you.
