I thought that to help people out I would post a couple of videos that show various techniques so you can learn how to throw a cast net. For what it's worth the second video is the technique that I use and it took me about 10 hours (and about 600 swear words) to learn really well.
My Tips for throwing a cast net (so you don't end up swearing and the net doesn't end up in the bin):
- If you can't get it right don't change everything at once. Make little adjustments to what you are doing and note when the net spread it is getting better (or worse).
- Don't be afraid to ask around for a demonstration.
- Remember that it will take some time and don't give up.
Good Luck
