24 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[...]

25 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 items at the same time, but cannot determine wher e each return originated – only when it was received. Examples 1 and 2 provide a look at the underwater world fr om a top view [...]

26 Whiteline The Fishfi nder 250/250C 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 returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom while a thick whiteline indicates a harder bottom. Normally , the Fishfi nder 250 uses a[...]
