The best transducer for ice fishing is just as important as the display. To accurately send and receive sonar signals, the best transducers take advantage of the latest technology. With the most advanced transducers, anglers can see video-like images of fish and structure directly below the hole, to the sides and in front. Live view sonar provides video-like imaging of the fish, structure, and the lure or bait. Or, you can use a broadband or dual-frequency transducer to capture the action on a flasher or graphic display.   Consider how the transducer will be deployed beneath the ice. A broadband or dual frequency transducer is dropped into the ice hole on the transducer cable with a float to keep the puck just below the ice. Live view or side view transducers are mounted to a pole and positioned below the ice. Then, the pole is rotated so the transducer can capture images in all directions.
