Hello there,

Very nice implementation. Could you please also add the Bill of Materials used so I could reproduce? :)

Thank you,

It really depends a lot on what you have available. The Standard Horizon ds41 is not available anymore. Therefore you need to find an alternative echolot that has an NMEA output. The rest is just an LCD display, NEMA GPS, SD card and the Arduino. All pins can be read in the Arduino file. The transistor is only used to flip the NMEA signal from the echolot. This also depends on the NMEA device you're using.
