Shoal Digger

[tokenfinn]

I was watching Canadian Sportfishing this weekend and there was a guy using a shoal digger by lightning series lures. He was using it catching whitefish. I had never heard of it before and I was wondering if anyone has has heard of it or had any success with it. Looked like a pretty good bait. It is slightly front heavy as you can tell, and when jigged it looked like a minnow feeding on bottom.
