After a couple of tries, it'll come naturally and you'll have
all of the live bait you'll want.
For manufacturers of cast nets there's a couple that I recommend.
The best of the best without a doubt is Calusa and Calusa Cracker
cast nets. Calusa is the highest quality, but pricey, and the
Calusa Cracker is a lower priced version of the Calusa and it
is an awesome net. I throw Crackers and will never go to a different
cast net. If you're just learning to throw and don't know the
bottoms of where you're throwing, I would recommend a cheapo net
from your local tackle shop. A good cheap net is Ol' Salt cast
nets from Betts. When you're ready to move up, I would recommend
a Calusa Cracker over a Betts Super Pro. The Cracker will open
easier and sink faster than a Betts Super Pro.
