The answer is the fish on the bottom right. All the arches are roughly the same length (and they are all quite short). But the thickness of the bottom right arch tells us it is the biggest fish. This fish is not a monster, but it would be a decent catch. [links]
Fish will show up on your screen as an arch (the reason why they are shown as an arch is explained in detail here). But it’s important to remember these arches can vary in size (length and width), and might not be a full arch – look out for those half arches too. The screenshot below gives some nice examples of different arches. They vary in length and width, and some are not full arches, but these are all fish. here
Now let’s imagine another scenario – again your sonar is stationary, but this time 2 fishes swim through your sonar beam, one big and one small. The big fish swims very quickly through the sonar beam, the small one swims slowly. Which one will make the longer fish arch on your screen? The answer is the small one. That’s because a slow moving object will leave a longer mark than a fast moving one, whatever their size. [links]
The most common mistake anglers make when reading their fish finder is thinking that a long arch means a big fish. This is not the case. On your sonar display, you should think of length as representing time. For example, imagine you keep your fish finder stationary in the water (in other words you are not reeling or trolling it). If there is a fish underneath that is also stationary, what will you see on your fish finder display? You will see one continuous line. That doesn’t mean there’s a blue whale stranded in the pond you’re fishing. It means there is a stationary fish under your fish finder, and it might be a very small one. [links]
Now you have spotted some fish arches, it’s time to make sense of what each arch tells us about how big the fish is. So let’s discuss length, thickness, and half or full arches. here
The size of the area you’re scanning will be affected by the angle of the cone. A wide beam cone scans between 40° - 60°, meaning you’ll be covering a large area. A narrow cone will scan between 10° - 20°. So make sure you’re aware of whether your fish finder is using a wide or narrow cone when you’re looking at the data on your screen. The Deeper PRO and PRO+ have wide and narrow beam scanning (55° and 15°), the Deeper START has a medium/wide beam (40°). One other point to remember about how you sonar works is that it is constantly sending and receiving data, which means your display will be continually scrolling. The current scanning data will be on the right – the further left on the screen, the older the data.
Screens come in sizes ranging from less than 4” to 10” displays. The larger the screen the more information is displayed at one time like the GPS and split-screen viewing etc. Fishfinder display sizes are something that you really need to think about in terms of what your fishing needs are and how much information you want to be displayed at any given time.
Just make a mental picture of your model’s screen folded right down the middle. Then mentally fold it at the base of the water column. Anything that is on either side of the boat will be displayed as a bright object with a dark shadowy shape. Long shadows mean taller objects are present. Anything that is right under the boat will show up in the water column. You can see how side imaging works with animation in this video:
The Garmin manufacturer has displays that you can read with ease with a backlight component. It has a battery recharge unit included with most styles, and it connects the right transducer.
My Eagle Fish finder isn't working properly. Yesterday, I was sitting at the landing and it was registering 60 ft of water!
The transducer is mounted on the lower right-hand side of the transom about 2 or 3 inches from the bottom of the boat and it sitting horizontal to the back of the boat. Is this the correct positioning? [links]
Hi guest !
Check your transducer to see if it is set at the right angle, also try cleaning the transducer they do need this from time to time. more
Nothing is more frustrating to a fisherman than spending a day on the water without even a nibble. With all of the technological advances that society enjoys these days, it is no surprise that technology has also come to the rescue of fishermen. A fish locator is a handy gadget that makes finding fish as simple as pushing a button. Eagle fish finders have hooked a large share of the sport fishermen market because of device accuracy and affordability. In this article, we’ll show you how Eagle products can help every angler reel in a great catch.
One of the most attractive features of the Eagle finders is the simple operating mechanism. Anyone can use it. Once you find a fishing spot that you think might be a winner, turn on your device and evaluate the depth and water temperature. The information will be accurate to approximately 600 feet and will appear in the corner of the screen. The sonar chart will scroll and display what’s directly beneath the boat as you drift or troll. By using the menu options you can adjust the sensitivity of the device. The fish will show as a straight line when you are stationary. [links]
Eagle fish locators come in a variety of models, all of which are very easy to use and are reasonably priced. The design of the units is ideal for small boats, kayaks, canoes and even floating tubes. As with all electronic fish finders, the transducer is the working element. The Eagle’s transducer has a suction cup mount that easily attaches to your boat. One of the most popular features is the large, bright screen that makes it easy to read the charts. The various models range in price from approximately $100-$500 and come with a 1-year manufacturer’s warranty. more
Yes, you’re likely to get the actual size of the fish is you look at the width of the fish arch. more
So, if the fishfinder doesn't show you the actual length of a fish, can it then show you the arch width? more
You will also see them in a yellow color, than in green color of vegetation. here
Also, if you're reading a deeper sonar, a bathymetric mapping system will come in handy in helping you create color-coded underwater contour maps. Aside from this, these maps will also display depth changes, and drop-offs and show you the best spots underneath your boat. [links]
