Welcome to IDO! We’re glad you joined us!
I’ve been trolling with lead core line for over 14 years and I like you, had many questions when I first started.
Here’s a few things you should know..
– A full core of lead core line is usually 10 colors (they also make 20 color spools now)
– Each color is 30 feet long so a full core of lead core line is 300 feet
– When someone says “put out 3 colors” – what they mean from your rod tip to your leader.
– You must attach a leader to your lead core. Here’s another thread that tells you how to do that: Best Lead Core Knot to Use
– You add and calculate your depth curve for your crankbait in regard to your leader length and then add the correct amount of lead core to achieve your desired trolling depth.
– Regular Leadcore line has a thick diameter due to the lead inside of the nylon sheath so you need to have a bigger reel to accommodate the lead core. How much you will want to put on your reel depends on how deep you plan to fish.
– Regular lead core (most guys use 18 lb) sinks 5 feet per color when trolling at 2 mph. The faster you troll – the higher your lead core line will raise up in the water column and the slower you troll – your lead core line will sink. A .2 mph difference in speed can raise our lower your leadcore line approximately a foot when fishing with 3 or 4 colors. Simply put – leadcore line is speed sensitive.
– The new Sufix 832 lead core line had a thinner diameter than the regular lead core line and therefore sinks faster – 7 feet per color when trolling 2 mph. Most guys like me are using 12 lb test.
– So…. if you’re only going to be trolling in water up to 25 feet deep – you only have to put 5 colors of regular lead core on your spool. If you plan on fishing deeper water – you will need to add one color per 5 feet of depth. If you’re going to be using the new Sufix 832 lead core line – the you can achieve 35 feet of depth using 5 colors.
– I recommend that you use some cheap mono backing on your spool before you apply your lead core.
– You do not need a line counter reel when using leadcore. You can simply count the colors. However, I use line counter reels for all my lead core set ups because it’s easier to put out 100 feet of leadcore line versus counting 3 and 1/3 colors to acheive a depth of 17.5 feet of depth (regular lead core). It also allows you to be more consistent and a line counter reel is not that much more money.
– When using a line counter reel – you must make sure that it is reading accurately. It does not count feet. It actually counts revolution of your spool and line is going in or out. So… if your spool is not full – it may be reading 14 -18 inches versus 12 inches. The way you can check it is you measure for example 150 feet in your yard and then pull off your line on your line counter reel and see what it says. If it says more than 150 feet – you need to add more line to increase the diameter of your spool so one revolution is 12 inches. Usually on most reels if your spool is full – you’re close.
Which lead core line you use (regular lead core versus Sufix 832 lead core) and what leader line you use (fluorocarbon, mono or braid) depends on your trolling scenario. Are you going to be trolling structure? Are you going to be trolling for suspended walleyes out in the open water? Lake or river?
