No Luck with downriggers!!!!!

[crispyclubs]

I live in northern Maine and I am relatively new to lake fishing. I bought 2 new Cannon manual downriggers, humminbird fishfinder, and 2 new trolling rods and have fished the last 3 weekends with no luck at all! I have been trying to fish for salmon and togue, using these huge Dave Davis spoons with a few rapala lures and live bait (smelts) and haven't even even gotten a nibble. I have about a 15-20" leader attached to the spoons. I have fished morning,noon,night been on bottom,middle, and top, trolled at various speeds .5mph-2.5 and see fish everywhere on the fishfinder.....but can't get a bite!!!! I'm wondering if the big spoons are a deterent or an attractor. I was told that using big spoons actually attract the fish but I can't get them to nibble.......Also I have my downriggers on each side of the boat and have seen most right in the back....The directions said either or???? I do notice that when I troll more than 1.5 MPH the down rigger cables make an annoying humming sound. Not sure if the fish sense this but I'm not sure if that is normal or not???????? Any advice would be greatly appreciated!! Thanks!
