Sea Striker Mackerel tree is a deadly rig for catching multiple baits at a time. Use it trolling behind our No. 1 planner with a 00 size Clark Spoon on the end. Use it to Catch Blues, Spanish Mackerel, Blue Runners and many other baits that can be caught trolling. Attach a sinker to the end and use it as a casting rig when the bait is too shallow to troll for.
