Leadcore line is simply lead wire inside the core of a braid. The wire is there for the weight only. Braid gives it the strength. Leadcore is available in many different lbs. The less the diameter the faster the sink rate. We suggest using no less then 18lb. 20-36lb is what we recommend. Leadcore allows anglers to adjust depth of lures by simply increasing or decreasing the amount of line that is let out of a reel. Leadcore is available in multicolor. We recommend multicolor. Every color represents 10 yards of line or 30 feet. It is recommended to let out one color for every 5-6 feet you wish to attain depending on troll speed, current or wind flow. Leadcore is the most effective way to gently troll a tube, sinking, plug, fly or eels down to suspending or bottom feeding fish. In conjunction with a fish finder, leadcore is another valuable fishing tool.
The Newell 235-5 is a great light weight reel with high capacity. The Penn 535 is also another good choice. You want to get the lightest reel possible so that you are comfortable using it. Lead adds weight and you want to get the right rod and reel combo. Graphite reels will get the job done. For backing you want to put on thin diameter with some decent strength. Braid or thin dacron. Leadcore comes in 100 yard rolls. Some dealers have it in bulk on the large spools. Leadcore will run about 10 dollars a roll, depending on strength. For what we do 5 colors to cover depths up to 20-30feet. If you plan on fishing deeper let more line out. It is said after five colors the more line you let out your lure will penetrate deeper into the water column. 5 colors will also mean lesser weight.
When looking at rods most good choices are in the 6'6"-7' range. If you can get away with a 6'6" rod you will have lotsÂ choices. St. Croix has the Premier series, pm610mf. This is a medium power rod 14-30lb fast tip. The reason why I chose this rod was because of the guides. When letting line out you want oversized guides to allow double uni's or similar knot to pass thru. Also butt length is important.Â From the center of the reel seat to the end of butt IÂ look for triggerÂ style rods at a max length of 14 1/2". Consider this when purchasing a rod.
For this illustration I will use uni to uni to attach main line to leadcore and then improved clinch knots to hardware.
When tying leadcore in the uni to uni knot removing 6-8" of lead will help you achieve a smaller knot. Use the inch worm technique to expose lead wire and pull back on the braid. After your break the lead off with your hand pull the braid forward. This will allow a limp section of braid to tie the uni to uni to main line or backing.
When your done you should have about 6" to tie your uni to uni or other knot to main line or backing.
After knot is complete, I tie a sampo ball bearing snap direct to lead line. At this point you can add a rudder if trolling tubes and line twist is present.
At the end of the other side of rudder you can put another ball bearing sampo. After that swivel install your leader. Leader length is preference, 3-4 feet is what I use. If using lighter leadcore allow some extra leader when big fish come to the side to avoid breakoffs. Leader material can be flouro or mono. Leader strength should be 30-50lbs. If using any swivels that are not black use a black magic marker to keep curious blues honest.
Here is a picture of the finished set up with tube added. The length of lead and leader has been shortened for illustration.
Leadcore can be used in the salt for tubes, plugs, eels, spoons etc. It also will help the sweet water anglers get in the strike zone for lakers, trout etc. This is a great alternative to downriggers.
Happy hunting and we will see you on the water!
