Our Double Fin 8" Flasher is designed specifically for Great Lakes Salmon and Trout fishing! The dual fin design allows for more consistent rotations in current and various speeds, ranging from 1.5 to 3.5 MPH. Heavy-duty stainless ball bearing swivels are welded on each end for durability and performance. These days there are an overwhelming array of flashers, but we aim to stick with what we know works. This flasher color and tape combination has been producing since the early 2000's by charging the glow in the dark tape with a camera flash before deployment in the early morning and relying on the UV for bright light conditions. These days we use an LED Black Light as well as a camera flash.
