Drive around till you find them, we run 1,200 to 1,800 rpm on big motor to cover water until find them,then slow down to 800-900. If you don't find rays depending where you put in, might make run down around poplar island if don't find anything closer . Try flats,coves, deep water drop offs on edge of flats, just have to cover water till you find them...The best tip: ask a crabber if you see one, they hate rays and will tell you to kill them all and normally point you in a direction to find them
