My 2 cents, the elbow potentially can have a strong current. So I have been told. When I went there wasnt any current (or fish) even though the dive master warned us there would be strong current and big fish. I have heard from others that the elbow is a spectacular dive when the current is running. Turneffe North is probably better suited to new divers. Then again, the local reef is fantastic and 5 minutes from shore.
