Answer 1

Correct choice: "to search" ... "locate"

Revised sentence: Since buying a metal detector, Mike Steel uses it to search for buried treasure, check his friends' teeth for fillings, and locate missing coins under the couch cushions.

Reason: "search," "check," and "locate" are parallel verb forms (with the initial "to" understood to apply to all three).
