Concave facets along the weights sides reflect light and sound, then redirect those signals outward in a starburst array that reaches nearby fish through the water. As the cannonball moves behind the boat, it produces a distinctive two-stage sonic signature and a fish-shaped pressure wave that can signal predator activity along the downrigger line. This combination of visual, acoustic, and pressure signals can draw salmon toward the Shark Cannonball and add another fish-attracting element to trolling presentations. Concave facets reflect light and sound, creating signals that target the lateral line of nearby game fish The unique surface redirects reflected signals outward in a starburst array to increase activity around the downrigger weight A two-stage sonic signature develops as the cannonball moves through the water, producing a distinctive acoustic signal The fish-shaped pressure wave can signal predator activity and stimulate salmon to swim toward the trolling spread To ensure your items arrive in one piece, some products are subject to an oversize packaging fee.
