I learned from Gil at a seminar last year.
I also watched the Calusa Video dozens of times.
I still stink at throwing...
You see, the boat is always moving. It's very hard to line up, get ready, and throw without missing the bait. I catch some, but I've had people on the boat that net HUNDREDS in ONE THROW!!!!!!!!!!!!!
I'll keep practicing, but it's easier (for me, anyway) to jig for bait later in the season. Netting is also VERY MESSY!
On the other hand, any "Spearing" net is very simple to use. I get TONS of Silver Sides (to use for Fluke and Sea Bass) with a small can of cat food tied onto the net (otherwise, the bait will float away).
