How does the bait boat sonar fish finder use and understand it?

 Some people buy an all-in-one smart remote-controlled bait boat with an integrated sonar Fish Finder and don't know how to use it or read the sonar signal，Here we explain how to interpret the sonar picture of the S5 Intelligent bait control boat by Sailvvay as an example.

1. How Sonar Works

Sonar technology is based on sound waves.The system uses sonar to locate and define structure,bottom contour and composition,as well depth directly below the transducer. The transducer sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off an object; then it uses the reflected signal to interpret location, size,and composition of an object.

3.How to set up sonar menu

The “setting” botton is used to access the menu system.When you press the “setting” botton once, the menu system immediately appears on the display.The menu system has 3 tabs:"Setup" and "Advance"、"Sonar", You can press the “setting” botton  toswitch between different menu tabs.

In each menu tab use the lower or  Upper Key of  rocker to select a specific menu item,and use the Left or Right Key of rocker to change a menu setting, then press the Power botton to return to the homepage

 

a) Sonar Sensitivity

Settings: "Auto", "1%" to "100%"Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time.There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish echoes if fish are present. As you change the sensitivity setting you can see the difference on the chart as it scrolls. Select "Auto" to have the unit automatically select the sensitivity according to the different water depths.

 

B)Depth Range

Settings: "Auto", “0-9ft" to "0-240ft" ("0-3m" to "0-80m") Select "Auto" to have the unit automatically select the Depth Range,the bottom signal is automatically placed in the lower half of the screen.Select specific value to lock the depth range to a specific setting.

 NOTE:

In manual operation, if the depth is greater than the depth range setting, the bottom will not be visible on screen.You can select "Auto" to return to automatic operation.

 

C)Fish Symbols & Depth

Settings: "On/On", "On/Off", "Off/Off" This feature identifies targets that meet certain conditions as fish.The microcomputer analyzes all echoes and eliminates surface clutter, thermoclines, and other undesirable signals. In most instances, remaining targets are fish. This feature displays fish symbols on the screen in place of the actual fish echoes. There are several fish symbol sizes. These are used to designate the relative size between targets.

 NOTE:

The sonar's microcomputer is sophisticated, but it can

be fooled.It can't distinguish between fish and other

suspended objects such as trotlines,turtles,submerged floats, air bubbles, etc.

 

D) Depth Cursor

Settings: "On", "Off" The depth cursor consists of a horizontal line with a digital depth box on the right side.The numbers inside the box show the depth of the cursor. You can move the cursor to any location on the screen, letting you pinpoint the depth of a target.

 

E) Simulator

Settings: "On","Off" The Simulator is a very powerful tool that simulates on the water operation. Use the Simulator to learn how to use your fish finder before taking your boat on the water. The Simulator Indicator will visible on screen when Simulator is setting to "On".

 

F) Units

Settings: "ft/°C", "ft/°F", "m/°C", "m/°℉"

 

G) Chart Speed

Settings: "10%" to "100%"

The chart speed is the rate echoes scroll across the screen.

 

H) Keel Offset

Settings:"Off", "-9ft" to "+9ft" ("-3m" to "+3m") Keel Offset will adjust the digital depth readout to indicate depth from the waterline or boat's keel. Enter a positive vertical measurement from the transducer to the waterline to read the depth from the waterline. Enter a negative vertical measurement from the transducer to keel to read the depth from the keel.

 

I) Sonar Chart Mode

Settings: "White Background ", "Blue Background", "Gray Scale" You can change the Sonar Chart Mode to suit your viewing preferences.

 

J) Surface Clarity

Settings: "Off", "High", "Medium", "Low" Surface Clarity adjusts the filter that removes surface clutter noise caused by algae and aeration. The lower the setting,the more surface clutter will be displayed.

 

K)Noise Rejection

Settings: "Off", "High", "Medium", "Low" The Noise Rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions and interference. This automatic feature gives you the best display possible under most conditions. If you have high noise levels, try using the "High" setting. However, if you are having trouble with noise, we suggest that you take steps to find the interference source and fix it, rather than continually using the unit on the high setting.
