I learned a lot about weight and diameter of cast nets this week,its all over the place.
I am really rusty on my Calusa 12 footer. Usually go to the boat shows and look for the demo area where they will guide you through the whole process. There are some nice videos on you tube but nothing like being there live with someone watching you. The commercial mullet guys here, make it look so easy throwing even larger nets with more weight designed for a fast sink....
The question than become how much weight on the lead lines and what size mesh on the monofilament netting.
A good friend of mine uses 1/4" which is really small on everything from mullet to cigars to pilchards. He says it will cover the spectrum.
Others use 5/8 or 1/2" on mullet 3/8" mesh on the rest. I even know one guy who uses lighter weight nets in shallower water.It's all over the place but good to know who does what. I carry the heavy nets and 1/2 and 3/8 but I may get more sizes of mesh.
