The HDT Stinger is compatible with streamers made of fur, feathers, or synthetic fibers. To space out the attachments on a fish imitation, use the actual length of the hook as a guide rather than treating its code as a standard number. The HDT 02 and 01 measure 78 and 60 mm, respectively, and come in packs of 10. The HDT 2 and 4 measure 37.5 and 30 mm, respectively, and come in packs of 15. All are made of high-carbon steel, chemically sharpened, barbless, and feature a black nickel finish.
