Well yes there is only one TM i believe but there are two Pokemon that natural learn the move dig, one being nincada
It is not possible to find the TM dig more than once. If you have lost or used it then you are out of luck.
As far as I know the only way to get another dig is to trade for a Pokemon that is holding the TM dig or to get it from another version
i want a Pokemon with dig for open the cove of the regis
You cannot not get another TM-28 [Dig]. However you can get your Pokemon to learn dig by breeding it with a Pokemon that learns it through levelling-up. mAvOoP
