The Panzar EX Popper 65 features a unique ‘Bubble Chamber’ open mouth design. This is based on how a jet engine turns low pressure into high pressure. The ‘Bubble Chamber’ will force water through the chamber and shoot it out of the top, creating more commotion than conventional poppers. When swimming beneath the surface, the Panzar EX Popper 65 will leave an enticing bubble trail, luring fish to strike.
