I saw on an earlier thread where a guy talked about using them this year. We weren't having much luck on Sunday turning any of the marks we saw on the graph into meat in the cooler. I saw them in my tackle box and gave it a whirl. Put it on and it caught one in ten minutes.... We all laughed cuz I told the guys on the boat we were gonna go old school.... Put it back in the water and it went off again in about 20 minutes.... But that was it for the day...
