Know-How to Read and Interpret the Fish Finder
To spot fish underwater, Garmin striker 4 uses ranging techniques as well as sound navigation. It can then sense the pulses reflected by the sound energy, thus making it easier for you to fish. You can see the places where the fish are in plenty and where they are less.
On the right side of the device is the readings of the water column. It is easier to know the depth of the waters you are fishing at. The point at which the boat is standing is the mark of zero. Whatever is underneath your boat at that time will be displayed on the right part of the Garmin 4 screen. Some minutes ago, images that were below the boat will be displayed on the left part of the screen.
Yellow will be a dominant color on your screen as it will represent rocks and other structures that are stable underneath the water. There will also be some weak spots of red and blue colors. If there are fish present, there will be steady returns. They will always appear in the form of arches and thus become easily identified.
Fishfinders will go up to 10000 feet underneath the waters to give readings of fish found or any other water objects. To get the fish, the fish finders can detect and sense air in the swim bladders. This air changes the path of the sound and can reflect the energy.
Customize The Fish Finder
Garmin 4 fishfinder will enable you to customize your findings as it has some control buttons. You are thus able to get fine-tuned readings, images, and other necessary details. There is the power button that enables you to switch on and off the gadget at your convenience.
You may also use the buttons to adjust the brightness level of the fish finder. Brightness can be adjusted in three levels, namely low, medium, and high. There is a button that shows different parameters to choose from. You can choose the type of screen display you want to use, be it full screen, a split zoom, a depth reader, among other choices.
There is a split frequency that shows returns ranging from 77 to200 kHz. This range option will help you change the depth scale to the desired value. By adjusting its sensitivity, you can see more targets. To know the fish depth, read the depth line option.
Always zoom often on the bottom to know the areas you are fishing over. If the bottom is hard, a thin line will be represented while a thick reading represents the soft bottom. Also, learn how to identify a thermocline when using a fish finder. The thermocline is a barrier to temperatures found in different water layers. They always show weak and broken readings on the screen, and you may confuse them with baitfish. If it is a thermocline, see if it has a consistent depth that appears for a long time.
Estimate the fish size
The arch will enable you to know the fish’s size when using a Garmin 4 fishfinder. If the arch is big, it means that the fish found is big too. Small arches also show that only small fish are available. You need to be extra keen when judging these sizes, as it may not always turn out the same.
Consider the thickness, fullness, and length of the arches to get the best fish size. Looking at the arch’s thickness will work best when determining the fish size as the arch length may not always show the actual length of the fish. Images of a full arch will be big and hence represent the presence of big fish.
Interpretation of arches
A sonar device in a fish finder enables the transmission of sound waves through the water. These pulses come into contact with fish and other items on the surface. They get reflected on the surface, thus producing arches on the display screen. Garmin 4 fishfinder shows arches that are either full or half to show the size of the fish.
Full arches will be displayed any time the fish swims and covers all the part of a sonar cone. If a fish swims partly on the sonar cone, half arches will be displayed. You also need to know that even big fish may partly swim the sonar cone, making the arch read half.
Whenever you see your fishfinder displaying half arches, it does not mean the fish is small. However, if this happens, the thickness of the arch will still be large enough and you can accurately determine the size of the fish.
Final Verdict
Garmin 4 fish finder will be the best option for you as an angler as it will suit all your fishing needs. It helps you trace the location of fish underwater and see their reaction towards the bait. You only need to read and understand it well to get accurate readings. Be sure to interpret the readings displayed on the screen of your fishfinder.
When interpreting arches, you need to be extra careful to don’t give the wrong predictions. Big arches will indicate big fish, while small arches will indicate the presence of small fish. Consider the thickness of the arches when determining the size of fish for accuracy. You will thus enjoy fishing.
