Well, the tried and true techniques paid off. Found several nice crappie holding on a deep drop off in about 6 FOW. Wound up keeping a limit and now I have access to a new lake!
Red/Chart.tube on a balck/chart. head.
So glad you did a number on that lake and now have a good place to fish!
Stayin' with what works and fishin' familiar structure will work on fishin' 'new' waters almost every time.
