How to Use a Portable Fish Finder?
To turn fishing into an easy and effective adventure, you need to know how to use a portable echo sounder. First of all, read the manual and learn the information the display shows. Different sonars have various sets of functions. The simplest can only show the depth, which, in many cases, is more than enough. So, your device should be properly connected, and the sensor must be correctly installed. After connecting the echo sounder and installing the sensor, you must configure the device itself.
For a more detailed picture, you need to switch to a narrower beam and increase sensitivity. On the screen, you will see graphics and numbers. The numbers are understandable: depth, water temperature, the speed of the boat. By experimenting with sensitivity, you can get images of fish, which, depending on the settings, will be shown as symbols or as an arc.

There are various models of a portable fish finder, but it’s up to you to decide which of them is best for your personal needs.
