The Michigan Stinger Scorpion spoons are among the most popular trolling spoons and consistent producers on the Great Lakes and elsewhere.
The Scorpions (2 1/4 inches in length) are the smaller version of the Michigan Stinger spoons and not the exact same shape as the spoons with the color examples you see in this catalog.
Originally, Stinger Scorpions were designed for walleye, but they also have gained tremendous popularity with lake trout in the Boundary Waters Canoe area Wilderness and the Quetico Provincial Park of Canada. I'm pretty sure they are not just limited to these regions as a trout is a trout for the most part. Just attach to a snap swivel and troll slowly behind the canoe (or off a downrigger, if fishing elsewhere). You can also cast this spoon into shore using a light or ultralight rod. Smallies will knock the snot out of it. Cast and slowly retrieve alongside weed beds and beware the large northern who will not think twice to nip it off. I don't recommend using a steel leader as this will make this a northern pike only spoon and may affect the lilting action. Use 6-10 lb. mono or a heavier braid with a small diameter. This spoon breaks all the rules with regard to the old saying "Big bait - Big Fish". The fact is large predators often feed on very small prey, and find these spoons irresistible. Excellent flash and flowing flutter as you drag it through the water. Due to changing days and conditions, you will want a 3-5 different colors in your tackle box when doing a remote wilderness trip. They're kinda hard to find out in the boonies and they eliminate the need for organic baits.
