how can i tell how far my fishing lures will dive?
I got some bomber-like lures at an auction the other day and i am trying to figure out how deep they will dive at 1 mph for trolling walleye. They have large bills on them so i assume they will dive deep. Is there any type of equation (example: 1/2 inch of bill for 10 feet of depth) to help me figure this out. I live on lake erie and lure depth can be critical! THANX!
