I am so hooked on copper that I have 8 rigs ready to go, starting with a 90' and in 30' increments, up to 300'. Then a 450. Alot of times with 2 of us fishing, I will start with a 90,120 and 150 on the port side and 180,210 and 240 starboard. Keeping about a 15'-20' spread between lines. IMO this makes for an efficient and effective spread for searching out the active feeders. If the mid-depth lines are getting all the hits, I will add dive bombs to the shorter coppers to reach the same depth. Then as the sun rises and the fish move deeper, the shallow rigs get swapped for the 270, 300 and 450. Also, the 30' increments are easier for me to remember the running depths of each. The 450 gets a TX-44. My walleye boards are tuned and marked for each length of copper for optimum performance and arranged in the boat to be deployed in the correct order. Anything to help setting up in the dark easier! To this I will add a large reflective chrome dodger by itself off the probe rigger ball about 1/2 way down in the zones I am covering to call the fish into the spread and then pick them off as the coppers come by. Hope this helps someone, or at least give them something new to try. Dave.
