When were limited to 6 rods, our spread is; 2 riggers with spoons, 2 divers with flasher/fly, and 2 core/copper setups with spoons or plugs. The deepest rigger will have the shorter lead 25-30' The other rigger will have a longer lead 40-50' The diver on the deep rigger side will enough line out to be running 5-10' above the deep rigger. The other will be set to run 5-10 above the shallow rigger. The deeper core will go on the deep rigger side, behind an inline board. This is a good way to search and destroy. If all the fish are coming at a set depth, then we will try and target that depth with more rigs. What setting are you using on your divers? Personally I like the bigger rings on the divers, or just the bigger Walker divers set at 1.5. The bigger divers set at 1-1.5 will run close to %50 of line out. (100 out=50' down) Like Phil said, the longer the leads from diver to flasher the better. If you have a small boat, of short working area, than long leads make it hard to net fish. Don't give up on the divers, get the setting right, and all will be good. If in doubt, watch this video. What do you have for a boat? If you have any pictures , feel free to upload them.
