Among Friday’s best bets on television:
In Season 4 of “Bering Sea Gold,” ambitious treasure hunters continue to brave frigid temperatures and brutal conditions — all as we watch from the warm comfort of our couches. 9 p.m., Discovery.
Watch “Airplane Repo,” because it’s fun to watch people chase the repo man down the runway as their planes take off. Season 2 begins tonight. 10 p.m., Discovery.
