The Dark Matter Leader Heli Safe from KORDA are leaders that are equipped with a Heli-Safe System and can be used in helicopter style in combination with both regular rigs and chod rigs. The leaders are provided with pieces of tungsten that help to sink it to the bottom. The Chod Safe System has also been applied to ensure that the bottom line can easily come loose in the event of a line break. A Quick Change Ring Swivel makes it possible to quickly change the rig.
