Garmin's Panoptix LiveScope is a live-scanning sonar for recreational fishing that provides high-resolution, easy-to-interpret images of structure, bait and fish in front of and below the boat. The transducer mounts on a trolling-motor shaft or at the transom. On the trolling motor, the transducer can be easily aimed forward or down. The product won this year's ICAST Best of Show award, announced last week in Orlando. It costs $1,499.99.
