Anglers have long relied on sonar-based “fish finders” to locate schools or fishing spots, but those devices only scan a limited range. Humminbird 360 Imaging provides a 360-degree view. A transducer mounted beneath the boat can project a wall of sonar in a circle up to 300 feet in diameter. Users can view bottom contours, structures, and fish on an onboard display that updates continuously. $2,000
