Mount it straight on a jig head suitable for its length, then retrieve it slowly or hold it almost stationary in the target depth. The tail moves with subtle twitches; excessive action will quickly drive the lure out of the zone.
The three sizes allow you to match the lure’s size to the prey you’ve spotted. The F2 attractant is built into the lure. A forward-facing fish finder helps track the lure’s passage in front of a fish, but this minnow can also be used without electronics, either on a vertical drop or with a controlled retrieve.
