-(으)면 gives the condition and 찾다 the finding — note it means both looking for and successfully finding, so context decides. 조금 더 남쪽으로 가면 찾을 수 있는 건데 'you can find it if you go a bit further south'; 번호를 모르면 찾기 힘들 텐데 'it'll be hard to find without the number'. One line uses the set phrase 틈만 나면, 'every chance he gets'.
