What do you do?

Greg Hackney has stopped on his best area and then made another spot change, but both yielded nothing. The bite has obviously been tougher than normal this week, but my question is what do you do if you are Greg Hackney at noon with zero fish?

 

He moved even deeper and is sitting in 40+ feet of water. Hackney caught a non-keeper moments ago, but that is it so far.
