200 kHz Sounder, Entry-Level Sonar
Simple to use but full of features.
Compare the FISH 4430 with the FISH 4431: The FISH 4430 provides the key functions of depth and temperature and the FISH 4431 also provides speed and log information.
Both the FISH 4430 and the FISH 4431 are ideal entry-level fishfinders, but pack a lot of power. Navman's SBNII technology means automatic range and gain settings maximize Signal Enhancement, Bottom Recognition and Noise Rejection for clear crisp on-screen sonar images for hassle free fishing. The professional fisherman and those who prefer a hands-on approach can take advantage of the manual range and gain settings.
