Furuno FMV603 Fish Finder Parts
The FMV603 is a compact video sounder with a dual-frequency transmitter using a single
transducer. Steady, non-fading images are presented on a 6" rectangular CRT with 4-level
quantization depending on received echo strength.
The FMV603 incorporates both 50kHz and 200kHz tranceivers for optimum shallow as well as
deep water performance. You have the choice of high or low frequency display, either with or
without Bottom Lock, or a simultaneous dual-frequency display.
A variable depth marker and noise limiter are standard features. Two alarm zones may be set;
one extends from the top of the screen downward, the other from bottom towards the top. When
they are overlapped, the overlapped portion becomes the alarm zone. The alarm works as either
a Fish Alarm or Bottom Alarm. This audible alarm is then activated when a fish school or the
bottom appears within the alarm zone.
In addition to manual phasing of the range, automatic phasing is provided so that the bottom is
always displayed on the lower half of the screen
