So you need some practice equipment?

First, you'll need to get yourself some chain. You can buy any chain you like, in whatever length gives you the desired weight. Personally I went with a 30' tow chain, which weighs in right around 20 lbs.
So, select your chain.

I prefer a leather sporran belt. That sporran chain is likely to chew up my kilt fer sure. Forget it, dude.

LOL. That chain is for those of us who really stuff their sporrans.
