When sandbass steal your shad...

Was bank fishing yesterday and was robbed blind by sandbass i think. Every fresh shad i put on a circle hook was ripped off. All i felt was a tap tap and it was gone. I even tried a double hook rig, didnt help. What do you guys do when this happens? Besides start trying to catch sandies...

Could have been gar or a bunch of 6" long channel cats.
Time to move as said above.

Try a smaller hook or a far larger shad. I'm assuming these were threadfins or small gizzards? I prefer very large gizzards, perch or cut carp/buff for this very reason.
