Trolling live or dead bait with a drop back is successfully used when targeting billfish.
A rubber band is attached to the mainline in the desired distance from the bait.
This rubber band is then attached to the release clip on the outrigger.
From the release clip the mainline hangs loosely in a desired length to the rod tip.
The reel is set with a drag of 25 – 33% of the line's breaking strength.
When the billfish strikes the bait, the rubber band snaps thereby giving the fish
time to turn and swallow the bait before the line is straightened and the hook is set.
