This deep running chain weighs 48oz when using the recomended 5 oz Joe Shute stinger.  The front squids are loaded with lead.  It tracks deep below the surface depending on your speed and how far back you troll it. It has been proven for both yellowfin(right in the middle even with long riggers) and bluefin(way way back). We recommend using a 5 oz Joe Shute with a Crystal skirt as the stinger. You can select your stinger on the product page. Feel free to experiment with other stingers.
Suggested Spread Location: Flat Line - close to the boat or near the back of the spread
