Compare the FISH 4431 with the FISH 4430: The FISH 4430 provides the key functions of depth and temperature and the FISH 4431 also provides speed and log information. Both models are ideal entry level fishfinders. The large digit depth displays also make them a great choice as a dedicated depth sounder. Multiple alarms provide a more sophisticated level of information.
