In Pokemon Emerald, how do you get Dig if you've used the TM and lost the move?

Question

I got dig in fallarbor town but I used it and put a different move over it. How do I get it again?

Answer 1

I'm afraid that's the only way to get the TM, and it's a one-shot deal.

If you need Dig tfor the field ability, you could try raising a Trapinch. They learn Dig through levelling up (lv 41).
