Doo-Dad's 1 oz Casting Spoons can be casted or trolled. For Northerns cast the Doo-Dad along weed-lines, or into gaps found in rushes. We recommended using 12 lb-15lb test line, and use a 6"-9" steel-on, or wire leader that is equipped with a good snap and swivel. The Doo-Dad Casting Spoons have been used effectively with a down-rigger system for Salmon and Trout. Casting Spoons can also be vertically jigged through the ice for Northerns and Lake Trout. 1 oz. has a number 2/0 Treble Hook.
