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:
