I was readingTrolling truths by Sep and Marilyn Hendrickson and a section titled Downrigger dynamics sunk in to my fish sized brain. They say that not accounting for the natural drop of the terminal rig is " The SINGLE BIGGEST mistake" that anglers make. Thats me thier talking about!. My question is how do you estimate natural drop of a 0000 dodger and a Squid?. It strikes me that this could be the reason I am catching 4 or 5 Salmon a day and reading others on this site are catching 20 that same day same place...
