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.

What’s the Best Portable Fish Finder?

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. When choosing, you should also pay attention to the power of the device – the higher the power, the deeper the device will function. In shallow water, a powerful product will ensure the display of even quite small details of the bottom.

The frequency of the emitter will allow you to receive data with minimum delay. This will allow you to instantly respond to the location of the fish and move the bait to that part of the water where it is located.

The sensitivity of the device affects the clarity of the image and reduces the amount of noise. According to portable fish finder reviews, it is best to acquire an echo sounder, whose sensitivity can be adjusted.

The diagonal of the display and the contrast of the image will allow you to get a high-quality picture, which is especially important in bright sunlight. A sound alert system would also be useful; if the fish appears in the beam zone, the system will emit a signal.
