Lowrance Elite-5X HDI

Lowrance Elite-5X HDI fishfinder reviewLowrance Elite-5X HDI is a fish finder equipped with the 250-watt transducer, using 50 kHz frequency to give underwater readings for maximum depth of 1000 ft. It achieves a very high-resolution imaging due to using a combination of traditional Broadband Sounder and Down Scan imaging used in Lowrance brand with brand-new HDI technology.

Downscan Overlay used in this model exceeds at finding structure but may fail to spot individual objects, including the fish, accurately. This drawback is overcome by a brilliant combination of Downscan Overlay with traditional sonar that is well-suited for identifying separately-moving objects. The result is the ability to display both structure and bottom on one screen, allowing to see simultaneously the moving fish and the static objects like rocks and submerged objects. The display itself is multi-window, allowing for 3-panel viewing.

To show the fish and the structure of bottom with better clarity, the readings are automatically adjusted by Advanced Signal Processing Technology, making the use of fish finder even easier.

Judging from user reviews, Lowrance Elite-5X HDI fish finder is very easy to use and is of great help. The features of this unit are praised in most of the reviews.

NorCross HawkEye F33P

NorCross HawkEye F33P fishfinder reviewNorCross HawkEye F33P model is yet another popular portable fish finder under 200, simple yet innovative, which makes it a great budget option. While showing the image that denotes the readings of structure, fish, weeds and other objects at the maximum depth of 100ft, this fish finder has a downside of not drawing the image. So while it may be too simple for anglers who are experienced, it is still a good model for beginners.

Probably the best benefit of this model is no doubt its small and compact size (can easily fit in the palm of a hand). As such, there is a variety of ways to use this portable unit, including mounting it on the boat using mounting tabs from the package. But mounting is not a requirement, you can also carry it in any small storage space, for example inside tackle box or in your pocket; else you can throw it into the water (either from boat or dock), and then optionally allow it to float/troll behind your boat.

Best Fish Finder Selection Guide

As there are too many of brands of models of fish locators, it is understandably difficult to narrow it down to the single fish finder that suits your needs and your very own fishing style. Add there transom mounts, flashers, sonars, echoes, transducers and the common person becomes lost in this quite easily. So, how to choose a good fish finder? Perhaps it’s to rephrase the question: which fish finder will help you to catch more fish? Keeping this important point in mind, you can read this fish finder selection guide we have compiled. Thus, the choosing process will hopefully become more simple and lead you to the best choice with the help of our information.

Transducer

The main part of any fish finder, the transducer is the element that keeps sending sound waves to show the picture of what lies underneath the water surface. This sonar signal sent by the transducer will then bounce off any underwater objects and return to be picked up by the transducer, to be transformed into an accessible form of the picture depicting said underwater objects.

The most important parameter to look for when checking the transducers is the cone angle. The bigger is the cone angle degree, the bigger perspective of the verges underneath it gives. As you want to locate more fish, you will require the extended coverage of the under water, which leads you to selecting the wider beam. But keep in mind that there is also a downside to this: rapid loss of strength and thus unability of deep water penetration when compared to the narrow cone. And vice versa, the narrow cone allows you to see a very deep picture right down to the composition of the bottom (even in shallow waters), but the width of the area covered will be smaller.

There actually is no need to choose one type over the other, since there also are dual beam transducers (also known as dual frequence), which are essentially the combinations of wide and narrow cones in single fish finder unit. Then there are even more specialized transducers with even more beams (for example 4). As expected, these cover even larger underwater areas and can produce 3D viewing images on their displays. And the last option we cover here is the side beam type of transducers, which emits signals to the sides and in this way increases the size of the search area, allowing to find more fish.

Display

The first important parameter of the display is the pixel resolution. More pixels means higher resolution, which allows you to see more details. But it also means a higher price of the model.
The suggested minimal resolution of the screen would, therefore, be 240(w) x 160(h) pixels – which is still pretty blocky in regards to the image. But the more money you are willing to invest, the better resolution, and the sharper image you will get.

Then, it’s arguably hard to discern data from even high-res display if the display size itself is small. Thankfully, the displays also come in different sizes and selecting a bigger sized screen will give you better and clearer picture. You will be able to differentiate such data as echoes and numbers without the need to strain your eyes or use the magnifying glass.

Budget display units are typically black & white while color displays are more costly. Color display provides a picture in millions of colors. If you are using the color display, it is easier to view what exactly is happening underwater, plus the screen itself is much more easy to view in bright daylight compared to the black & white version.

Power

Power of fish finders measures in watts and is a very important feature, for it provides you with more usable depth, better speed of displaying and updating your readings, and increased effectiveness overall. This means that while you can still get away with lesser wattage models in shallow waters, for fishing in deep waters (great lakes, oceans and the likes), powerful units are a must. We would recommend the values of 600 watts and 1000+ watts for shallow waters and deep waters respectively.

Frequency

Frequency of fish finder model is an important transducer feature tied directly to its cone angle. Standard frequencies found within most transducers are 200 kHz (max), 192, 83 and finally 50 kHz. Higher frequencies come with the benefit of providing you more advanced details on the display. There are fish finder models with single frequencies, dual frequencies, and multiple frequencies available.

Fixed or Portable

All fish finder units can be divided into two types: fixed fish finders that require to be mounted onto watercrafts, and portable fish finders that are fully self-contained.

Fixed units are most likely the better choice for watercraft owners and settled fishers, seeing that they will be able to mount it to any location on their boat. Typically these are mounted either on the trolling engine, hull or stern. Each setting corresponds to owner’s certain preferences or needs.

If you are leasing your boat or prefer ice fishing / “fly-in” fishing, it’s more suitable to use a portable fish finder. Portable fish finder packages include transom mount for installation needs, with the transducer being attached to the transom via suction cup; they also come with battery power supply and special carrying case.

GPS-Combined Fish Finder Unit

For those looking for the fishing tool that is most advanced, the addition of GPS seems to do the trick. The Global Positioning System (GPS) helps to calculate your exact location using the help of satellites. Needless to say it is a must-have for serious fishers, and why should you use it separately when a combined GPS fish detector saves you both space and money, not to mention is very convenient?

The benefits of adding GPS to your fish finder are various. For one, you will be able to mark the hot fishing spots on the GPS map, and then you can find them anytime you need them and return to exact same spots in the future. By the way, marked GPS spots are known as waypoints, and typically most combination units will allow you to mark hundreds or even thousands of waypoints.

If you have selected one of the fish finding units with charts and background maps inclusion, GPS will also allow you to navigate through the waters.

Finally, use of GPS increases your safety by the simple fact that you will not get lost as GPS will always easily point you home. Consider the cases when your fishing happens throughout several different locations during the day, or situations when severe weather suddenly rolls out, and you lose sight of the landline. With GPS, you can always tell how far you are from home, and in which direction you need to move in order to reach it.

Fish Finder Working Principle

To better understand how to use your fish finder, you should, of course, understand how it works. It uses sonar technology that displays underwater objects with the help of sound waves. First, the sound wave produced by the fish finder is sent through the water by the transducer. As it penetrates the water deeper and deeper, this sound wave spreads forming a conic shape (usually called a beam). Within the range of this beam, any objects encountered by the wave trigger the reflection of the signal back to the transducer.

After this, transducer calculates the amount of time which has passed between the instances of sending and receiving the bounced back signal. This allows to measure the distance, which is then shown on the display. In case the sound wave does not encounter any obstacles on its way, it will reach the bottom. The bottom can be either soft or rocky. In case of soft bottom composed mostly from mud and weeds, the signal simply gets absorbed, while a rock bottom will reflect more or less strong signal back tot he transducer.

In the end, sonar signal reflections are being read by fish finder and end up displayed on the screen. This way, fish finder lets you know about the bottom and everything encountered between it and the transducer location.

Sonar beam angle is known as the cone angle (measured in degrees), and the wider it is, the more of underwater area will be covered. Each fish detector model comes with own cone angle, and there is a big choice of these, especially if you add the fish finder models that are equipped with multi-beam sonar technology for covering an even wider area.

The Conclusion
