The Humminbird 981c SI uses sonar to reach out 240 feet on each side of the boat to give anglers an image of the bottom with photograph-like resolution. Side-imaging shows detail of underwater fishing structure and can help spot bait balls. The unit also provides two-dimensional fishfinder images and has a seven-inch color TFT display designed for split-screen data viewing. The 981c SI uses a transom-mount transducer, can be gimbal- or flush-mounted and has a suggested retail price of $1,750. Humminbird; (800) 633-1468; www.humminbird.com
