Works best when fishing for these species of fish: Crappie, sacalait, spotted perch, sun perch, bluegill, etc... The Rockport Rattler Panfish jigs come with an Arberdeen style hook in Black Nickel finish in three hook sizes, #4 (smallest), #2 and #1 (largest). Each contains a rattling chamber in the body of the jig. To enhance the fishing attracting qualities of the built in rattle, we use high quality light reflecting eyes. The Rockport Rattler Panfish jigs work extremely well with your favorite crappie grub or tube and/or tipped with a minnow. A keeper barb is not needed as the plastics will hold on to the rattler chamber quite well, unless you are using a very large tube.SPECIFICATIONSWeight: 1/16 ozHook Size: #4Eye Color: RedQty/Pack: 3Color: LimeTruese
