equipment questions

[dvasques]

Two Flakes has answered that but I'd like to know where else do you put your flag? And where do you have your beam bags on? And what's the real use of wearing a belt?

What's the difference between single sided, double sided and long neck beam bag?

This might be stupid but how does the chain clip works? And what's the use?

Considering that we play at the beach here (so no shoes necessary) I'm thinking of buying:

- white ball flag
- blue beam bag (pending to know double sided or whatever)
- Info package (wallet, info cards and pencil)
- wrist down indicator

Anything else I should get?
