Video Sounder

Clutter

Cruising noise, polluted water or plankton can clutter the screen with low signal level ech- oes. This situation can be improved by ad- justing the CLUTTER function.

Detecting area

The detecting area varies with the main beamwidth of the transducer. Objects out of the main beam but close to the beam will be presented less densely, smaller in size and at a lower intensity.

Generally, beamwidth depends on Tx fre- quency; a narrower beamwidth is usually ob- tained at a higher frequency. The beamwidth of the 200 kHz is narrow, thus it has the ad- vantage of higher resolution. On the negative side, fish at the sides of the boat can be over- looked because of the narrow beamwidth.

Display color

A color video sounder displays an echo in a color corresponding to its strength. The GP- 1610CF displays echoes in eight colors: red- dish brown, red, orange, yellow, green, light-blue, blue and black.

Frequency

The frequency of the ultrasonic pulse used in video sounders is between 15 and 200 kHz, and the GP-1610CF provides both 50 kHz and 200 kHz. The 200 kHz frequency offers a sharp, clear-cut picture since its beamwidth is narrow. However its use should be limited to shallow waters since its pulse is easily at- tenuated in water. The 50 kHz frequency pro- vides a longer sounding range since its pulse it is not as easily attenuated.

Gain

Gain adjusts the sensitivity of the receiver. It should be set at the point where excessive noise does not appear on the screen. Usually, use a high gain setting for deep water; a low one for shallow water.

Interference, noise

Interference can result from other acoustic equipment which operates on the same fre- quency as your own or electrical equipment on your boat which disturbs the video sounder. In most cases interference can be suppressed with the noise limiter.

Picture advance speed

Picture advance speed defines how fast the video sounder picture moves across the dis- play screen. Several speeds are available in- cluding freeze, which lets you stop advancement to observe the picture more closely.

Pulselength

Pulselength is the length of time the transmit- ter in the transducer is turned on each trans- mitted ultrasonic signal. Pulselength is linked with range and thus cannot be selected. The higher the range selected the longer the pulselength.

Pulse repetition rate

The pulse repetition rate defines the number of pulses transmitted within a certain period. The more pulses transmitted the greater the detection accuracy. The pulse repetition rate is automatically changed with range.

Resolution

Resolution is the ability of the video sounder transducer to discriminate returning signals. The higher the transducer frequency the bet- ter the resolution.
