The right half of the display screen shows the complete sonar picture at its original scale. The left half shows a portion of the original picture at 1/2 depth scale. 2X Zoom –– Displays the 2X zoomed picture on the f[...]

12 • Whiteline — controls how the unit displays information about the bottom type (har d or soft). With the Whiteline ‘Off ’, all high-intensity bottom returns will display as red. With Whiteline set at ‘Normal’ or 1-100%, this option can be used to better determine bottom hardness. See page 24 for mor e information on this feature. •[...]

20 unit will automatically use GPS ground speed (if available via NMEA input) for comparison on the calibration. If a GPS ground speed is not available, use either your boat’ s speedometer reading (not always accurate) or a stopwatch to determine your speed over a certain distance (distance / time = speed). It is recommended that the calibration [...]

21 Understanding Sonar If you are unfamiliar with basic sonar , or need help determining what is displayed on the graph, this section may be for you. This section is intended to help the novice user gain some understanding of how the Fishfi nder 320C operates and how it can help improve their fi shing productivity . T o understand what the unit i[...]

22 On the W ater T ransducer Cover age 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 pr ovide a “wide” 40° cone angle, with a coverage width that is approximately 2/3 of the wa[...]

23 Understanding the Gr aph It is important to understand that the unit does not display a 3-D representation of the underwater environment. The unit can display multiple things at the same time, but cannot determine wher e the return originated – only when it was received. Examples 1 and 2 provide a look at the underwater world fr om a top view [...]

24 Whiteline The Fishfi nder 320C can help you to determine if the bottom is hard or soft. When the sonar soundwaves are refl ected back by the bottom, a hard bottom will return a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom while a thick whiteline indicates a harder bottom. Normally , a red line is used to show [...]
