i have a diamond justice and some how the cable slide on it broke. is does anyone know where i can buy a new one?

If you take it to your shop they should replace it at no charge. I had the same thing happen a while back and they replaced it for me anyway...

thanks

They have plenty of replacements at most stores like BPS, Academy, or any archeryshop.
If you want to do it yourself its obviously very easy. Consider it an opportunity toupgradethe OEM slide.

Give the saunders hyperglide cable slide a look. I have no experience with it but I do understand that it may allow you to squeak out an additional few fps
