Fish recognition

The echo strengths shown on the A-scope can be useful in recognising the type of fish. Different species of fish have different sizes and shapes of swim bladders. The air in the swim bladder reflects the ultrasonic pulse, so the strength of the echo varies between fish species according to the size and shape of the swim bladder.

When fishing among a school of fish and catching them, note the fish species and the strength of the echo that it returns on the A-scope. Then, when that particular echo is seen at future times on the fishfinder, it is likely to be the same fish species.

5-6 A-Scope perspective view

The strength of echoes on this view are determined by the’height’ of the echo shown on the screen.

5-7 Fuel display (4433 only)

To show the Fuel display, press DISP and select Other Tab, select Fuel and press ENT.

There are no options.

(See section 3-3 Setup > Fuel for information about setting up the fuel values. If the number of engines is set to 0, the fuel features are turned off.)

Used shows total fuel used since this was last reset with the Clear Used command.

Remaining shows the amount of fuel remaining in the tank(s).

Flow shows the fuel consumption per hour. For twin engine installations, the fuel flow for each engine is shown separately. This is useful for checking that both engines are under the same load.
