The Wally Diver is a rattling plug with a slim profile but round
cross-section. Pike, zander, perch and Canadian lake trout like it very much. I
use the largest model, CD7 Magnum, almost exclusively for
trolling, where it is one of my most
successful lures. probably the loud rattles give it a large area of awareness,
which is especially important when
trolling. I also have the feeling, that the rough surface somehow makes it
more attractive to the fishes senses.
