Our friend and boat owner/captain Zach was very excited to discuss an exciting idea to ad "bubble" jets to the high speed trolling lures we had been using to catch Mahi, Wahoo, and Tuna. I agreed to give it a shot and designed and printed several prototypes that we improved until we were satisfied with 3 different jet heads. Our research also led us to use glow in the dark materials in both the printed heads and in the skirts where possible.
