Crappie fishing this weekend...when spider rigging I can see my double minnow rigs and sinker as plain as day at the 10'-11' mark on the screen. However, I tried a to "spot and stalk" a few with a single long pole/jig and I can't seem find my jig on the screen for nothing. I'm using a 1/4oz head and a 3" bait...so not a small bait. Anyone else have this issue? Recommendations?
