These JohhnyJigs Casting Jigs are a 40 gram Jig Lure that can be used in a variety of fishing conditions. Great for any saltwater fishing application over reefs and in any depths when casted, allowed to sink, and retrieved. We have had great success in any conditions in landing Kingfish, Wahoo, Tuna, Bonito and even Sailfish. These Jigs can even be used in Slow Pitch and Vertical Jigging in Depths up to 250 feet. Deep Lake Trout Fishermen are starting to fall in love with these jigs as well !!!
