My blog readers know that I spend a LOT of time trolling in the winter, spring, summer, and fall. This technique can be a bit boring but is a great way to target salmonids (click here and here for examples) and non-salmonids (click here and here for examples) by probing large areas of their habitat using multiple lures. I deploy two distinct sets of “tools” to support my trolling habits: lead core line and a portable downrigger. This blog discusses the former, and more specifically the setup that I have used for years, and which has worked well for me. For the record, I also troll for smallmouth bass using floating Rapalas, but that approach is fundamentally different from placing lures at depth and is therefore not discussed further.
