Frequency
Your sonar unit can transmit signals at 83 kHz and 200 kHz. The de-
fault frequency is 200 kHz, best used in shallow water (about 300 feet
or less). This frequency is the best choice for about 80 percent of the
fresh and salt water sport fishing applications. When you get into very
deep salt water, up to 1,000 feet, the 83 kHz frequency will work best.
The 200 kHz transducer will give you better detail and definition, but
less depth penetration. You will not get as much detail or definition with
the 83 kHz frequency, but it has greater depth penetration and up to
120
°
of wide fishingfinding coverage. Remember, all sonar units typically
read deeper in fresh water than in salt water.

Fish I.D.
The Fish I.D.
feature displays — as fish — targets that meet certain
conditions. The microcomputer analyzes all echoes and eliminates sur-
face clutter, thermoclines and other undesirable signals.
