I am not saying that we should go back to fishing with our bare hands, but if an "amateur" fisherman plays so dirty, what pleasure does he find in it?
Hooks, lures, rod, snack and technology. But what pasture, what straight. Fishermen will be useless to wish "good fishing" in an attempt to boycott them, they will have a considerable advantage. Today they can find and catch fish easily with the Deeper Smart Sonar Pro +, a mini depth sounder.
Deeper Smart Sonar PRO + comes with a whole range of features designed in detail to help anglers locate and track fish in lakes, rivers and seas.

How the Deeper Smart Sonar PRO + mini fishfinder works
The device creates real bathymetric maps from the shore to show water depth, temperature and more.
Access to this data is easily done from a special smartphone app.
The mini sonar has a range of 100 meters and a large 90 kHz scanning range which allows it to cover large areas.
Implacable
Despite its very small size, the mini depth sounder is amazing. In addition to the functions already mentioned, the device is able to instantly change the range, becoming more and more accurate as you circumscribe the area.
The most notable feature, however, is that the mini depth sounder can map and monitor water up to 80 meters deep to improve the ability to locate fish.

Not enough: the presence of a powerful dual beam transducer allows the Deeper Smart Sonar PRO + to scan every 15 seconds and has a distance (margin of error?) from the target of 2,5 centimeters.
In other words, it gives very, very accurate readings. The mini fishfinder has its own built-in Wi-Fi connection to transmit the detected data to the smartphone in real time.
