    Bother are fine. Some people use a dash to explain, and others use a comma. BTW, this is a colon :. – michael_timofeev Mar 26 at 3:55

Both are correct.
1) The use of comma is for depicting a brief pause, when one has to provide side information about something.
2) The dash is used for explaining something.

Both are used for providing some explanation about a thing that is mentioned in the sentence, an explanation without which the sentence would make sense too, but the writer wants the reader to know more about that thing.
It depends upon the writer what he chooses to use in such a situation.
