If you want to increase your catch and cut down on the fishing time, the Garmin Fishfinder 90 is your ideal solution. It uses sonar tracking technology to reveal underwater fish on an FSTN black-and-white screen. Equipped with a dual-beam transducer, the sonar fish finder lets you choose between a narrow view and a wide view based on the population. The wide view reveals larger population in shallow waters. Incandescent backlight makes it convenient to read and find fish even in the dark. Additional features include zoom for easy viewing and alarms corresponding to fish size. Low battery and water depth are also indicated by this fish finder. Overall, this dual-beam transducer fishfinder is a remarkable device that helps you catch more fish.
