I'm looking to monitor my fuel consumption and was recommended to use
FloScan. It looks very good and can interface with GPS to determine
nautical MPG, as well as GPH and total fuel used.

Couple of questions:

1. Are there any other devices like this out there I should look at?
2. From their website I see gauges, but can't tell if fuel consumption is
just cumulative or can be reset w/ each fuel fill?
3. For MPG or GPH does it only report instant, or can you also get average
values?
4. I have two gensets on my boat. One is generally running while we are
cruising and we spend a few days at a time at anchor, again one is running
much of the time. Do you get another gauge for the gensets to monitor how
much fuel they have consumed to get total fuel consumption? Seems like
overkill, but I can't think of another way.

Thanks in advance,
