The lever drag is used when trolling for big game fish such as yellow fin tuna or marlin. When trolling, the lever is set just above the "free" posiiton. Then, once a fish takes the bait, the lever is pushed into the "strike" position. When the lever is in the "strike" position you are able to employ the precise amount of drag to control the fish without breaking the line if the fish turns and makes a hard run. Remember, it is important to make your drag settings prior to the cast.
