NAVDoctor NMEA 2000 Diagnostic Tool

SKU: DIG-0001

“NAVDoctor is the perfect NMEA 2000 diagnostic tool for dealers, installers and boat builders. It turns any mobile device into an NMEA 2000 network analyser, creating simple and clear web pages that show the health and status of your NMEA 2000 network.”


NAVDoctor is a portable NMEA 2000 network diagnostic tool/tester. It allows you to quickly check and diagnose the NMEA 2000 network. It combines the functionality of existing NMEA 2000 display programs and test equipment into a single, cost effective, simple plug ‘n play box.

It’s self-powered from the network and creates a local wifi point for a mobile phone, tablet or PC to connect.  Once connected, you simply access functions through a web browser so there’s no complicated software to install.

NMEA 2000 networks are based on a robust Canbus architecture, but one bad device, cable or termination can have a detrimental effect on performance.  Fault finding can be time-consuming and tricky, so having a NAVDoctor in your toolkit, will save you time, money and frustration.

NAVDoctor is an essential tool for every marine electronics technician or installer and also offers the capability of printing a network health check certificate to validate an installation and improve customer service.
