A hook-setting device, including a flange that is fixed and generally transverse to a fishing line or leader, is adapted to resist the force of a fish strike on a hook or fly and to also indicate a strike by its movement in the water. The latch structure comprises a base, a plate, a rotating element, hooks, a magnetic element, springs, locating posts, a latch element, a pushing element, and screws. A laser pointer is mounted on one side of the circumferential headband, and a battery pack is provided to power the laser pointer. When the control signal is received, the memory access controller stores the data present on the data bus in memory cells of the memory array.
