YEp, the Navman plotters and Ffinders are fantastic. If you can afford to look at this one, take a look at the Trackfish6600. This is a dual finder/GPS unit, but the real clever part about it is the Deisel Fuel
computer. This is not a toy computer, It is a real McCoy that does a very professional job and very very accurate. There are plenty of Petrol ones out there, and petrol is very easy to monitor
, but Deisel is not, because of two reasons. It is returned and it changes in Volume rapidly with temperature. So accurate measuring has to be temperature compensated, which is not easy nor cheap
. In the past, the only way to do an accurate job, meant that the fuel
was large and expensive. And I mean EXPENSIVE. There are many makers of electronics
that add Fuel monitoring packages in either stand alone or combinations, but none have been worth a darn. Navman are the first to actually produce a real deal package in an affordable price
range. This was independantly tested by a very well known *(famouse in NZ) Marine
Len Gilbert. Kiwi boaties reading will instantly know his name. At first he was sceptical, as he has been down this track before and no one has been able to do it for real. But Navman totally blew him away.
Anyway's, the advantages of fuel computing, you can work out the most efficient RPM/speed/fuel usage for the conditions. It calculates the amount of fuel in the tank(without having to use a sender) and it calculates the range your vessel has in the conditions you are in.
