Understanding Your Sonar Unit

Factors influencing target (fish) display - The shape and size of this mark is influenced by a combination of factors:

Boat speed - The shape of the target changes along with your speed. Slower speeds return flatter, more horizontal marks. As your boat’s speed increases, the target will tend to thicken and arch slightly; until at fast speeds the mark resembles a double vertical line.

The depth of the target - The closer the target to the surface the larger the mark on screen.

The frequency of the transducer - The same target will appear differently when the transducer frequency is changed. The lower the frequency the broader the mark (50/83 kHz).

200 kHz
 - scans a narrow area but produces more detail. Use this setting when you are in deep water and the 200 kHz signal is so strong that you want to retain this higher resolution picture. It is good for finding fish that are near the bottom or close together.

455 // 800 kHz - excellent frequencies to identify baitfish from gamefish and to read structures.

NOTE:  Read and re-read your Owners Manual.  Then make the manual adjustments needed to maximize the use of your sonar unit.
