Check the listing for details. Kable Leadcore Leader Heli-Safe. Condition: New. Listed at 13.31 USD. These leadcore leaders are 1m in length, which makes them perfect for pinning everything to the lakebed and protecting fish from line damage during the fight, but aren’t so long that they adversely affect your casting. Not only is this a brilliant anti-tangle set up, but it is also very safe for the fish as it incorporates the Mini Heli-Safe System – a more compact version of the original - and ensures that the lead will come off whenever it needs to. It also incorporates our No-Trace Safety System, which ensures that in the event of your main line breaking, the hook link can easily come free of the leader, and each pack contains two spare No-Trace Beads (these can also be bought separately when you need more). The top rubber on the No-Trace Safety System can be set close to the lead when.
