Jones’ story took me back 15 years. On a full-moon summer night, I, too, was trying to figure out how to drop baits into the shark zone out beyond the first breakers. I hopped on my surfboard, a live bunker clenched between my teeth, and paddled off into the night. About 300 yards out, I heard a splash, followed by what sounded like an explosion. The monstrous 5-foot tail of a thresher shark slapped the water at face level. I spit out the bunker and paddled as fast as I could back to shore. That was the last time I attempted that method of bait deployment. I went on to test others, including three-man slingshots, modified potato cannons, and remote-controlled model boats—all with limited success. My kingdom for a drone.
