If angler Russ Luhm spots Spanish mackerel schooling at the surface or sees them on his depthfinder as he works a school with deep-diving lures, he’ll fling a Stingsilver or other heavy metal spoon at them. 

The tactic works even while he is running at trolling speed. However, if a few casts reveal that he is in the thick of the fish, he may stop the boat, bring in the trolling lures and start casting and jigging for Spanish mackerel to fill his ice chest. Sometimes, the heavy casting and jigging spoon attracts a big king mackerel.
