We use the same sort of rig here - a fairly small spoon with the hook removed and then suspend a jig or glow hook 6 - 18 inches below that and bait with corn or maggots. It can be jigged or dead sticked.
Someone told be about a fisherman using an attractor rig through the ice last year and doing very well. It sounded like a spreader rig with some blades or small flashers attached and hooked to a small motor that caused the rig to rotate - kind of trolling in place. The fisherman jigged near this attractor rig and did very well. I guess it is supposed to simulate a school of feeding kokes. I haven't found anything like that on line or in any catalog. Anyone familiar with this kind of rig?
I may try to make one out of an umbrella rig and some blades or small flashers. Any ideas for a motor to rotate the rig?
