Screen Color & Resolution is an essential factor in your selection. Color screens are the new norm on today’s fish finders. A color screen enables you to more easily decipher objects in the water, giving you valuable insight into your game fish. Also consider the amount of pixels on your screen—the more pixels, the greater level of detail you can see. LED backlit screens provide brilliant visual display, particularly for fishing in low-light conditions.

There is not much that is more relaxing than spending a beautiful day out fishing in your boat. One thing that may make the day even better is a fish finder GPS, so you do not go home without some delicious fish for dinner. On eBay, reliable sellers offer a broad range of new and used fish finders for you to choose from, including brands like Garmin, Lowrance, Eagle, and Hummingbird. With your new color GPS fish finder, you can enjoy a full color display, along with features that may include screenshots, fish and depth alarms, zoom, and dual imaging. The Garmin 546S Marine GPS find finder, for example, features a chart plotter, sonar, an anchor alarm, sunrise and sunset calculator, and marine cartography software included. No matter which fish finder GPS you decide upon, feel confident that you are receiving high-quality products and convenient shipping options that will ensure that your order makes it to you quickly.

Unless you are an experienced fishermen, you will only use one type of beam in order to find fish. A wide beam transducer covers a large area but provides less bottom detail and often has a less powerful frequency of around 50 kHz. Narrow beam covers less underwater but provide more detail and bottom definition from the additional frequency around 200 kHz.
With the Fish Symbol feature disabled, an angler can learn to distinguish between fish, vegetation, schools of baitfish or forage fish, debris, etc. Fish will usually appear on the screen as an arch. This is because the distance between the fish and the transducer changes as the boat passes over the fish (or the fish swims under the boat). When the fish enters the leading edge of the sonar beam, a display pixel is turned on. As the fish swims toward the centre of the beam, the distance to the fish decreases, turning on pixels at shallower depths. When the fish swims directly under the transducer, it is closer to the boat so the stronger signal shows a thicker line. As the fish swims away from the transducer, the distance increases, which shows as progressively deeper pixels.
Do you prefer having more detailed and high-contrast visuals on your fishfinder? Color LCD options from Academy Sports + Outdoors can ensure you don't miss a single catch. With higher-quality screens, you can zoom into specific sections of the water and even target specific fish. With additional sensors, our collection of marine GPS can track the movement of fish in real time, allowing you to trail and snag them before they swim away. Academy also carries portable fishfinders as well as castable fishfinders which are great for kayak, surf or bank fishing.

Higher frequency transducers have shorter wavelengths and more wave cycles per second, which means you can visualize more details (smaller fish) but have only shallow to moderate depth capacity. One sound wave at 200kHz is slightly longer than 1/4", so a 200kHz sound wave will be able to detect fish as short as a quarter of an inch. A 200kHz transducer has a range of only about 600'. High frequency provides a crisp, clear picture of the bottom with the tradeoff of less depth range. For best resolution, choose 800kHz or 455kHz transducers.


Choosing the perfect fish finder for your requirement is hard with many features such as imaging, power and more. The main purpose of a fish finder is to catch more fish with the screen displaying the fish and underwater structure and physical objects. Other information such as water temperature and depth are common on the majority of devices with many high end fish finders providing much more.

Power output is measure in watts, often represented by the “W” symbol. With more power you’ll get clearer, more-accurate readings, and you’ll be able to find fish in deeper water. Units with limited power won’t always send the signal out far enough and you can get poor quality images. Look closely for a good power output and frequency options. The right combination can help you choose the right unit, based on overall ability. You’re looking for balance of depth, power and clarity of image.
Here’s a useful tip for judging the width / thickness of a sonar return: switch on the vertical flasher (also know as a-scope) on your fish finder if it has one (to do this on the Deeper App, go to Settings > Sonar > Vertical Flasher). The vertical flasher on the right side of your screen will show you exactly what’s under your sonar at this exact moment. You can use it for vertical jigging, and of course forice fishingtoo. For judging fish size, look at both the thickness and width of the returns on your vertical flasher. A larger fish will give both a wider and a thicker return.

By calculating the amount of time between when the sound wave was sent and when it bounced back, it measures the distance and shows it on the screen. If the wave doesn’t encounter anything on its way, it reaches the bottom. If the bottom is soft and it’s just mud and weeds, the signal gets absorbed. A rock bottom will reflect a stronger signal back.
