Navman 4430, 4431, 4432, 4433 Fishfinder

Not to be outdone by all of Garmin’s recent fishinder releases, Navman announced a new series of grayscale fishfinders as well. The Navman FISH 4400 series consists of four new models, the 4430, 4431, 4432 and 4433, and replaces the company’s existing monochrome sounder line-up. Offering a greatly increased display resolution, twice the ping rate of its predecessors for better shallow water performance, and maintaining Navman’s functional styling and ease of use, fishermen now have several new and exciting choices for accessing the information they need to improve their time on the water.

Each device in the 4400 series fishfinder line offers a varied feature set, allowing boaters to select the device that makes the most sense for their needs. Key features of each model include:

  8. Hi,
    I have a Navman 4433 Fishfinder and have lost the rubber fins off the speed paddlewheel on the transom transducer rendering the speed readout not operating. This has happened before and I bought a replacement paddlewheel. I can no longer get a replacement where I got the last one and ask if any one knows where I can get a few or is there a Northstar compatible part. Navman part ref is 46302.
    Thanks, Greg. (australia)
