Spearfishing wahoo or mahi?

One of my goals this year (2021) is to spear some pelagics. I'm out of JAX, so it'll be a long haul. Anyone have any experience to share that might help a brother out? My expectation is to freedive (really, just snorkel), since taking a tank down for pelagics seems counterproductive, but I'm happy to be wrong.
Anyone use flashers? Do they work? How deep? So many questions...
Also, anyone in the St. Augustine/Jax area who might want to buddy up, let's talk. Alton, I already know you're in.

5-6 years ago a DIY story was published on making and using flashers to attract Wahoo for fishing with rod and reel. I have forgotten if the article was in Fla Sportsman or Sport Fishing magazine. I was bored so I spent over $120 and built a set of beautiful flashers, but have yet to use them. The article was written by two anglers that claimed they work great. The article provided photo's of their set of flashers and Wahoo landed. They fished offshore of either N. Broward County or Palm Beach County. .
To give you an idea of the size of my non metallic flashers the bottom weight is a foot plus in length and is filled with lead. I used prismatic tape in four colors on flexible material (Don’t remember the type of material as I experimented with several different types but its probable PVC) and encased the flashers in very thick clear waterproof tape. The flashers are suspended from a float and hang close to the water’s surface near the boat. Chum is also used. The flashers are tethered to a vertical copper colored cable by snap swivels. Each flasher is leadered with wire cable and spaced about 18 inches apart or more so they do not tangle with each other. Wire is recommended do to the possibility of a toothy fish hitting one of the flashers or the main line. They are designed to flutter in the current as the boat drifts slowly along. That is the purpose of using light non metallic material that will suspend, flutter and flash. The reason my cost was so high i had to buy the prismatic tape in bulk (four colors) to get the size i needed. I have enough tape left over to make three more sets of these. LOL
I can sure see how they'd work for predatory fish. Makes sense....I just didn't like messing with them.
@osprey11 - very cool!
