Poppers fall into two basic categories: cupped-face plugs and pencil poppers. Most anglers are familiar the first type, which are relatively easy to work with an intermittent jerking action that creates a "pop-pause-pop" action. Speed of retrieve is adjusted according to species: relatively slow for striped bass, a bit faster for bluefish, and much faster for tunas and most tropical species. Though poppers were once crafted from wood, Bob Pond popularized them with his Atom Striper Swiper, which was, and still is, made of synthetic material. That led to the development of many other salt water poppers, including the Yo-Zuri Hydro Tiger, Gag's Grabber, Creek Chub Striper Strike and Cordell Near Nuthin.
