use a mesh bag, and pop a few weights in them. u have to know the species u are targeting and use the proper bait. some fish can be very picky. also you can throw in a lightstick to intice their curiousity. toss it in and give it 15-30 mins.
the downside of chumbags is that you can attract unwanted fish, i.e. sharks
also if you are chumming, it is usually recomendable to avoid doing so near public beaches and such.
