Several years ago I had a NAVMAN F3100 FUEL Instrument on my outboard engine boat. I loved that little gizmo. Yesterday I was watching an episode of MIGHTY SHIPS that featured the 530-foot sailing yacht WIND SURF. They showed some scenes on the bridge. In one close-up I saw a NAVMAN instrument. I couldn't tell which function it was providing, but it was the same innovative, small digital display with four buttons that I used to have on my 22-footer.NAVMAN made really great stuff, particularly their instrumentation series. I think it was a big loss for marine electronics when NAVMAN went under, shortly after they were bought by Brunswick. Only a vestige of NAVMAN continues today, involved in the GPS fleet tracking business. Some of their marine electronics wound up with Northstar, but then Northstar was acquired by NAVICO.
The NAVMAN 3100 FUEL instrument was a much better device than the Lowrance HDS and EP-85R combination that has replaced it. I would buy another NAVMAN 3100 FUEL instrument today, if there were one that could integrate with a modern NMEA-2000 engine and other displays. Sometimes progress does not really bring improvement.

There were no problems ever with the NAVMAN FUEL 3100.
