Transducer Coverage
The area covered by the transmitted sound waves is determined by the cone angle of the transducer
and the water depth. Cone angles may vary between different types of transducers. For example, a 50kHz
frequency may provide a "wide" 40° cone angle, with a coverage width that is approximately 2/3 of the water
depth. As shown in the sidebar, the 40° cone angle (50kHz frequency) approximately covers the area of a
20 foot diameter circle at a 30 foot depth. A 200kHz frequency may provide a "narrow" 10° cone angle,
with a coverage width that is approximately 2/10 of the water depth. As shown, the 10° cone angle (200kHz
frequency) approximately covers the area of a 6 foot diameter circle at a 30 foot depth.
When using the Fishfinder 320C in 'Dual' frequency mode, the unit transmits both 50kHz and 200kHz
signals at the same time. The 'Dual' frequency capability of the Fishfinder 320C allows the user to have a
large coverage area and still retain good bottom resolution. When in 'Dual' frequency mode the unit uses the
narrow cone angle (200kHz) to display detailed bottom information, keeping "Dead Zones" to a minimum,
and the wide cone angle (50kHz) for the large coverage area.
Fish returns from the wide and narrow beams will appear differently on the display. The wide beam
tends to show longer fish returns than the narrow beam.
