I got one for a steal and thought I hit the jackpot. Then I used it. I could only see the bottom. No jigs. No fish. No structure, etc... The whirling sound was calming, but that's about it. I had a cool way to hold the transducer. thread it down a piece of PVC pipe. That kept it straight. A leveling bubble on top helped too. A lot of tinkering for little payback. Maybe I'm using it wrong. Now I'm going to use an Eagle flasher that my father-in-law gave me. My dream is to get a Vexilar, but I'm saving slowly.
