The tactic is simple. Don a wetsuit, flippers, and a lure sack, grab a rod and reel tied to an artificial plug, and swim to where the fish are. “Casting is the toughest part. Remember, you are swimming the whole time. It’s like you are sitting in a chair—there's not much leverage.” Silva uses an 11-foot surfcasting rod and submersible reel made by ZeeBaaS. He also wears a portable SOS unit on his arm in case something goes awry, as well as a water bottle for emergency hydration. His flotation comes in the form of a 7mm wetsuit, as well as an additional 5mm wetsuit vest. Both hands are gloved, but the right glove has webbing between the fingers to help him turn. His fins are custom-made, with spikes on the heels so he can get traction on wet rocks or reefs.
