Good spotting ambrose
You will need cleats and a life jacket. Basic cleats cost under $20, and you can bolt them onto an old pair of runners, once you have all the holes lined up and drilled, use some Lock tight so the bolt dosnt loses until they rust on, and an inflatable life jacket (much better because they stay out of the way until required) $70 these are just ball park figures, you could find them cheaper.
This gear will be an investment, because you can use it to target any species off the rocks, black drummer, luderick, kingfish, Bonito, salmon etc etc
Scout out your locations, and keep an eye on the swell forecast on a site like seabreeze.
