How do I know if my driver is GRD or SD?
I'm trying to figure out whether my driver is classified as GRD or SD. I need to know this information for some specific reason, maybe for compatibility or requirements check. How can I find out?
What does SD mean on jewelry?
I'm curious, could you please clarify for me the meaning of the term 'SD' as it's commonly found on jewelry pieces? I've noticed it on several occasions and I'm wondering if it stands for a specific metal quality, a manufacturer's code, or perhaps it holds some other significance within the jewelry industry. It would be greatly appreciated if you could shed some light on this matter for me.
