Vertical jig with 6-ounce Krocodile spoons. Mepps Lusox spoon is good. Find fish on locator then measure line out by using rod as yardstick and fish just above them. Spoon should be jigged with full sweeps of the rod, pulling spoon five or six feet at a time. Let spoon settle on slack line,this lets the spoon settle downward imparting its special action according to the design.
Fish always hit on the fall.
You won't feel the strike,but will notice the timing by watching your line. Reel rod tip down to water's surface and set the hook. Spring, early summer. Learned from Rick Hobbs, Clearwater Lake Lodge,Manitoba, Canada. Put puff of air in tail of crawler and it will float above bottom where it can be seen by trout.
