Best bet: No cold front is expected this weekend. Big structures usually hold fish after repeated winter fronts, so wrecks, artificial reefs and tall ledges on the 10 fathom line could be productive.
Spear tips: The gear and techniques spearfishermen use while fishing from oil rigs can work in our area. Rig divers use a riding rig, which is shot from a speargun but is not attached to the spear. The strongest spear head is used, a detachable slip-tip with an extra-long stainless steel cable. The cable line is crimped to the spear and attached to a rope about 4 to 5 feet long with a brass clip looped to an eye on the end. After firing the gun, the diver holds the rope while trying to bring up the fish and keep it from wrapping around the rig legs. Divers can let go of the riding rig to prevent being dragged too deep.
