Although fish finding units are user-friendly yet they require some basic knowledge and help to setup and configure before initiation. There isn’t rocket science behind this, you just need to learn a few tricks and tips to set up fish finders, down scanning, side scanning, structure scan and furthermore particular sonars for particular fish finding units.

For beginners, I would like to tell you about side scanning sonar. Side-scan sonar is usually referred as an alternative term in fish finders such as bottom classification sonar, sidescan sonar, side-scan sonar, side-imaging sonar. It is one of the classes of sonar framework utilized to effectively make a picture of substantial ranges of the ocean bottom.

Steps-By-Steps to Setting up Side Scanning

The two most important things to consider for improving and setting up your side scanning readout or structure scanning (side scanning & down scanning) are the following:

  1. Setting the range and sensitivity(gain)
  2. Adjusting the Contrast.

For further clarification and better understanding, I’m currently taking Lowrance HDS-12 Gen2 Touch as an example and will tell you how you can modify these two things in this unit.

1. Setting the Range and Sensitivity (gain)

In Lowrance HDS-12 Gen2 Touch, for setting the manual range:

On account of setting the manual sensitivity (gain):

2. Adjusting the Contrast

The second important thing to look for side scanning setup and improvements is adjusting the contrast. Generally in Lowrance HDS-12 Gen2 Touch, we are given the options of setting the contrast either manually or automatically simultaneously.

So if you learnt how to adjust the contrast and range of that unit then most possibly you can do it on other fish finders as well.

1. Setting the range and sensitivity (gain)

Similar is the case for setting the range and sensitivity (gain) in other fish finders. In order to set the range and sensitivity gain, two things are important to consider doesn’t matter which fish finder you’re using:

2. Adjusting the contrast

In other fish finders, you’ll get the similar options of adjusting the contrast manually or auto-contrast depending upon the interface of that unit but principle will remain the same in all fish finding units. Side scanning can be done in same way as we did with Lowrance HDS-12 Gen2 Touch.
