What Do Different Frequencies in Fish Finders Do?
A fish finder uses different frequencies to locate fish. The lowest frequency is used in shallower waters, while the highest frequency is used in deep water. Choosing a frequency for your particular needs will determine how sensitive your fish finder is. High frequencies are more sensitive, but they are also less effective in shallow water. portable fish finders for canoes
Low and high frequencies work at different speeds and offer different degrees of detail. Low frequency fish finders are suited for freshwater fishing, while high frequency units work best in saltwater. A 20-degree beam is common in freshwater fish finders. However, a low-frequency model will cover most of the average boat’s area in shallow freshwater.
Low and high frequency fish finders use different beam angles, but both can identify fish within a wide area. High-frequency fish finders use narrow beam angles to locate fish close together. Low-frequency fish finders use a wide area to capture information beyond their transmission cone. Although low frequency fish finders can provide more depths, they may not provide as detailed information as their high-frequency counterparts.
The frequency of a fish finder is important because it determines the depth of an image and its detail. A fish finder sends out sound waves, which are reflected by air inside a fish’s swim bladder. The transducer then converts these sound waves into images.
Fish finders come in different color palettes. For instance, an orange-colored fish finder will detect soft bottom while a blue-colored model will show fish that are near hard surfaces. Most models allow you to change the color palette depending on your preferences. A fish finder with a soft bottom will show the colors orange and blue, while hard surfaces will show up in darker colors.
Fish finders also represent fish as arches. The size of the arches correspond to the size of the fish. A full arch will indicate a large fish, while a half-arch means a small fish. When you’re new to using a fish finder, it might be confusing to understand where these arches should start. A big arch with vibrant colors means that the fish is big. Alternatively, a small arch without much color will represent smaller fish.
Another difference in the frequency range between CHIRP is the range of frequencies used. CHIRP frequency bands are high and medium. High frequencies can identify fish within 600 feet of water, while medium frequencies can detect fish in deeper waters. However, you need to choose a frequency that is suitable for your fish finder’s use.
