Went out with a buddy today and was amazed at what he did. He has a wooden pole with a tennis ball that he used to tap the bottom of the boat. Had I not seen it it would have never believed it. He would find fish, set the anchor on the TM and start tapping. Within a couple of minutes the finder would fill up with fish he’d stop and they would disappear. He also had a device in the bilge with a motor and rubber mallet that would tap too, he said he prefers the stick better and it did seem to work better. Anyone else do this
