The POP-ORCA features Shimano's unique Bubble Chamber, an open-mouth design based on how a jet engine turns low pressure into high pressure. The Bubble Chamber forces water through the chamber and shoots it out the top of the lure to create more commotion than conventional popper-style lures. The lure also swims beneath the surface and leaves an enticing bubble trail that is sure to entice fish to strike. This unique design makes the POP-ORCA much easier to work than conventional poppers. The lure features through-wire construction and incorporates high tensile strength hooks to stand up to abuse from the large saltwater offshore species it was designed to target.
