Fish finders are very popular among anglers today, because of their really great accuracy of spotting the fish that lies under water. If you want to make the best out of your brand new fish finder and star catching a lot of fish, these simple steps to tune your unit will help you right away.
Make use of the auto mode: While you may have a real knack for guessing the right settings the first time you set foot in new waters, it is highly recommended to start your fish finder in auto mode. Especially in water with plenty of suspension particles in it, the auto mode will give you a good starting point from which you can steer in any direction you think necessary.
Tune sensitivity to detect thermoclines:Thermoclines are what are known as temperature barriers, and they show the difference between the layers of water. They will appear on the screen of your fish finder as thin faint lines. How can they help you? Usually, fish hide just beneath or under thermoclines, since they have specific temperature preferences for their environment. Make sure to finely tune the sensitivity of your fish finder to start detecting thermoclines.
Make use of the zoom function in deep water: When you reach deep waters, start using the zoom function. Your screen may look like there is absolute silence down there, but the truth is screens have limited resolution (number of pixels) so they cannot discern between movement of fish and water, if the fish hide at the depths of the abyss. By making full use of the zoom function, the screen will adapt and will start offering you information on the movement detected at the bottom. This technique is particularly useful in deep waters, and it is always recommended to get a fish finder with better zoom and sensitivity.
