better images as you decrease the chart speed to match the speed of
your boat.
If you are at anchor, ice fishing or fishing from a dock, experiment with
a chart speed of 25 percent. If you are drifting slowly, try a chart speed
of 50 percent. When you are stationary and a fish swims through the
sonar signal cone, the image appears on the screen as a long line in-
stead of a fish arch. Reducing the chart speed may result in a shorter
line that more closely resembles a regular fish return.

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.
