The Little Cleo is the Kastmaster's softer sibling. Where the Kastmaster is a tight-wobble missile, the Cleo has a curved spoon-bowl shape that swings wider and slower in the water — better for cold-water fish that won't chase a fast-moving lure.
The most-fished sizes are 1/3 oz and 1/2 oz, in chrome, gold, "red devil" (red-and-silver), and the iconic Acme "rainbow trout" paint job. Drop the lure to depth, then retrieve at the slowest speed that keeps the wobble engaged — usually slower than feels right.
Trolled at 1.5-2.5 mph behind a planer board or downrigger, the Cleo is one of the most reliable lake trout and coho salmon lures ever made. From shore on a stocked rainbow pond, a steady slow retrieve through the cruising lane outfishes plastics most days.
