This type of lure has been widely used in Sweden for over 100 years with exceptional results on both fresh and saltwater fish, year 'round. As a general rule, the larger sizes are for game fish in deep water lakes. The smaller sizes are for panfish in shallow lakes or trout, bass, etc. in rivers. All sizes will produce game fish and panfish if both types inhabit the same waters. These lures are forged of solid brass and all models are furnished with red plastic flippers for more action and attraction in the strike zone.
