Fishing on the water demands a quality fishfinder, that’s a known fact amongst any anglers today, but to make a good decision on what type of machine you need is another matter altogether. The market includes Chartplotters, portables, combo units etc., so let’s start from the bottom and learn about the technology before you go out and purchase.

Basics
The old technology is called sonar is what every fishfinder operates by. A sonar produces a sound wave-shaped as a cone and goes straight down to the bottom. It is also called a beam, and when this beam hits a structure or fish it reflects back and is registered and displayed on your screen. The unit measures the time the sound wave was sent and received, calculates the difference and “paints” the object on the screen.
Today’s machines have several features to consider and you should have at least a working knowledge of them so you purchase a machine that suits your specific needs. Think about the type of fishing you do, you do not need a high-end Chartplotter when you are actually fishing in small lakes.
LCD Display
LCD displays are measured in pixels and as in photos, the more pixels the clearer and better display. The type of display you choose is most important to pay close attention to different models and their specific features. There is two main types of displays, color display and grey scale LCD`s. Be aware of that some greyscale displays make it even easier to read your display and determine what structures and what are actual fish. The costs can be held down considerably by picking the right display.
The Transducer And Cone Angles
A transducer is a unit that turns the electrical signal from your transmitter to sound waves and beams it out in the shape of a cone. It is attached to the fishfinder with a thin cable and it operates with a certain cone angle which simply is the wideness of coverage in the water. The higher the cone angle, the greater the coverage. The cone angles vary from model to model so have this in mind when you look at all the features of the models you are considering.
Some models have higher frequencies that give you a superior resolution, different beam angles etc. Be sure to purchase a transducer that has a frequency that is the same as your sonar measured in kHz.
The transducers are usually mounted at the stern of the boat, right in front of the engine and with no obstructions, which is very important. It is vital to select a transducer that suits your unique situation when it comes to installation on your boat.
Installation Types
Pay close attention to the way your unit is installed in your boat and transom mount transducers are usually associated with stern-drive and boats with outboard motors. Other types are mounted through the hull and as a rule, have to be a high-frequency model while others are mounted on your electric trolling motor.
Sonar Update Speed
In basic, the faster your sonar updates, the clearer and better your image and you will see a more detailed report on your screen. Also, notice that the deeper the penetration the slower the update speed and the shallower the speed will be faster. Certain models update the machine at 40 times per second in about 50 feet of water.
Thermoclines
Some models have this great feature and thermoclines is simply the line where colder and warmer water meets. Some fishfinders show this and it is useful as some fish prefer colder water as some warmer. Identifying thermoclines are an important feature is you are hunting a specific species of fish and how they react during the day.
Finally
A fish finder is an essential tool and can be a costly investment in your fishing equipment so do your research properly and pick the best fish finder for your needs…

Lowrance Elite-7 HDI Fish Finder

The Lowrance’s new product has two main tools one is for finding fishes and other for navigation, these Chartplotters / fish finders have been included in by the company. With an 800×480 pixel 7-inch display you get an extra clear view from the 3D SONARS or GPS mapping packages and Broadband. The display is really a thing which is worth the price. With this being said, on comparing it with the screen of an iPad Mini it is just a little bit smaller.
HDI technology means that the power of two imaging systems joined together is in your hand which distinguishes clearly between fish structure and arches and shows the bottom clearly.
Both high-resolution Down Scan SONAR and Broadband SONAR can easily be viewed on this Lowrance Elite-7 HDI FishFinder, this transducer, which is nearly equal to any other transducer in size, can be installed quite easily; so that you may get to see echoes from the broadband SONAR with echoes of high-resolution 3D SONAR.
Lowrance Elite-5 HDI Fish Finder

There are two advanced imaging technologies built into this fish finder. You can use them individually, together on a split screen or be overlapping one another for the in-depth view of all available data on one screen. This technology isn’t something you will find on cheap fish finders, and it allows for much greater precision when tracking the ground or movement of fish. No fish finder review is complete without mentioning one more advanced feature found on the Lowrance Elite 5 HDI: a built-in GPS antenna with 16 channels. This allows you to navigate the waters like an expert, and you have the option of adding an external antenna if you wish.
I recommend the Elite 5 HDI for serious anglers interested in advanced technology at a reasonable price. Those looking for a more basic model may find the dual-imaging processing features a bit too much to handle…
Raymarine Dragonfly-5 Pro Fish Finder

If you are looking for a tool that would help you to improve your fishing experience, then you should consider getting Raymarine Dragonfly 5 Pro FishFinder.

This device has a brilliant and larger 5-inch screen with 480 x 800 resolution display having 256-colors with a backlighting feature which allows the user to see detailed and clear image no matter what type of lighting there is or whether it is day or night.
The new screen display is really the only thing that has been changed and the software and the transducers have been taken from its earlier models of 800 and 600 series. The same large digits which give the reading about depth, vessel speed, and water temperature took up very much of display.
There are many different versions included in the Helix 5 series with some having only the sonar, while some having side-imager with GPS.
The Humminbird Helix 5 SI GPS Fish Finder is an ideal angling tool for an amateur as well as for seasoned fisherman because its cost doesn’t include a lot of money and fits perfectly for both.

The Garmin GPSMAP 78Sc also allows you to determine the altitude, collect weather data and locate your direction using a 3-axis compass.
This is a high-quality compass that compensates for tilt and ensures you stay on the right path when on land or out on the water.
