Set the strike drag with the rod securely in a holder. The scale should read between 25 and 33 percent of the unknotted line strength when the drag starts to slip. 30-lb test line (shown above) should have a strike drag setting of between 7.5 and 10 pounds.
Light Tackle Drag Setting (Inshore)
If you set the drag on a light-tackle outfit (12-pound test is illustrated above) with the rod tip pointed at the scale (top image), the reading should be about 15 percent of the unknotted line strength. When the rod is in the fighting position (bottom) friction will increase the drag.
