1. Color Configuration: 15 color ranks indicate the strength of response. There are 7 color configuration patterns (0–6) that can be selected in menu 2.

2. Water Temperature Graph: Displays changes in water temperature to help identify tide changes and select fishing points. Can be turned ON or OFF in menu 2.

3. Fish Alarm: Sounds an alarm when a fish school is detected. Settings include:
- S: Detects both large and small fish schools.
- L: Detects only large fish schools.
- OFF: No alarm.

4. Thru-hull Water Temperature Sensor: Optional sensor installation for FRP boats to monitor water temperature.

5. Echo Sounding: Uses ultrasonic pulses to detect fish and measure depth by calculating the time it takes for reflected waves to return. Displays size or density of fish schools.

  • Page 34: General Imforation Of Fish Finder

    GENERAL IMFORATION OF FISH FINDER 1. THEORY OF ECHO FISH FINDER Theory of fish finder is same as echo. Ultrasonic pulses transmitted from the transducer into the water are reflected from fish school or the sea bottom and then they are received by transducer. Fish finder converts round-trip time between the time and the ultrasonic wave is transmitted and the time the reflected wave is received into distance and measures the depth It displays size or density of fish school, the outline of bottom or nature of bottom on the screen in different colors.

  • Page 35: How To Distinguish The Fish School

    2. HOW TO DISTINGUISH THE FISH SCHOOL Important is comparison between display of fish school and catch It is possible to distinguish the fish sort by display of fish school to some extent. But even if fish sort is same, it's form making school is different according to difference of fishing ground and difference of time (day and night, four seasons, variation of current).
