Best Fish Finder Buyer’s Guide

It’s easy to get lost in product so many features. While taking the most important decision. When it comes to choosing a fishfinder. How does it will help me to catch a lot of big fish? The best fishfinder reviews will help you to find out a perfect suitable fishfinder for you.

For those who don’t know, fishfinder comes with several things you need to consider before you actually spend the hard earned money. Before picking a fish finder you to consider the types of the fish finder, whether it includes GPS or not, display resolution, how much transmitting power you need and in which frequency fish finder work best in inland, coastal or deep water?

The Technology behind a fishfinder? 

There are three types of fish finder are available; dedicated fish finders that perform no other function, combination products that also include a chart plotter, and multifunction network systems offering a smorgasbord of potential functions.

 The Types of Fish Finder

Best Fishfinder

Dedicated Fish Finders

Dedicated fish finder is a perfect suit for a small boat and kayak for fishing small inland lakes within your limited budget. Those types of fish finders equipped with the bigger display and the most cost-effective performance. It shows you what’s below water in its display. Some dedicated fishfinder you can usually add a GPS sensor later to many units, turning them into chartplotter combos.

Fishfinder/Chartplotter combo.

If you have a big boat than Fishfinder/Chartplotter combo makes sense. Combo units are helpful for most owners of medium boats. You can use GPS for navigation to the fishing grounds, view only the fishfinder or view both on the split screen. Combo unit gives you lots more data underwater environment, bottom structure, vegetation, and fish.


Multifunction Network Systems

All the major manufacturers of the fishfinder provide multi-function network systems. They usually support a huge range of data sources including radar, raster, and vector GPS charts. They have also Bluetooth/ wi-fi features that allow you to control their unit from your iPhone or Android Device. Your fish finder often uses an external module to get all sources of necessary data. Multifunction network systems come with multiple-display which is great for the medium or large boat. Manufacturer of Multifunction network systems updates their device every time increase its capabilities to get the best out of it.

Transmitting power

The power of a fish finder is a very crucial factor to consider before making the purchase. The performance of a fish finder depends on power transition of a fish finder which is directly related to visibility of silt-laden water, depths, and effectively separate targets from down structure. With just only 200 watts you can able to see the shallow water Inland Lake. For Most coastal water, a 500-watt fish finder should have plenty of power. For blue water anglers, you need to take 1,000 watts or more.

 Display (Resolution, size)

A maximum number of vertical pixels mean higher depth resolution, as each pixel represents less depth. The number of pixels in a screen’s horizontal axis determines how long objects stay on screen before they scroll out of view, of significant importance with split-screen displays showing narrow columns of side-by-side information. The higher the screen resolution the more information can fit on the screen.

More pixels per square inch will give you a superior detail of surrounding structures and enhanced split-screen images. You can see the very small detail on high-resolution large screen the air bladders of smaller fish, near the bottom fish, separate targets from one another. Note: the contrast of the display must be sharp in order to use the resolution. Like many features, you get what you pay for with display resolution—the more resolution is the better.

Screen sizes refer to the diagonal (corner to corner) distance in inches across the screen. Widescreen displays show you more meaningful information when you split the screen to display more than one type of data, showing your GPS chart, radar screen, or returns from more than one transducer.

 Frequency of the transducer

The transducer

The transducer is the heart of any fish finder any system. A transducer is a device that converts electrical energy into sound waves and back again. A transducer sends out sound waves that expand as they travel forming a cone, they bounce off the bottom, structure, and fish. The receiver picks up the returning sonar wave and the sonar unit digitally process the signal to become what you see on screen.

Fishfinders operate into three different type frequencies those are single frequency transducer, dual frequencies, and multiple frequencies. Dual frequencies transducer comes with both 20 and 60-degree cones. Most transducer comes with either 50, 83, 192 or 200 kHz frequencies, all in direct relation to the cone angle.

Higher frequencies give detail resolution on your screen and the perfect view from a fast-moving boat. But don’t penetrate as deeply as lower frequencies. Inland shallow-water anglers generally best for higher frequencies of 200 kHz, 400 kHz or 800 kHz. For maximum depth, use lower frequencies.

  • Higher frequency transducerssend the short length of a wave with more wave cycles per second. High frequencies give you greater detail to detect very small objects over a smaller portion of water. High frequencies show less noise and fewer undesired echoes while showing better target definition.200 kHz works best in water under 200 feet/60 meters and when you need to get an accurate reading while moving at faster speeds.
  • Lower frequency transducersabsorb sound waves at a slower rate for low frequencies and the signal can travel farther before becoming too weak to use. The beam angles are wide at low frequencies, that means it spread out more is better suited for viewing a larger area under the boat. One sound wave at 50 kHz is able to detect fish with large air bladders, slightly longer than an inch. This Lower frequency transducer can see deeper, they may not give you a clear picture of the bottom. Low frequencies use wider beams that help you to find out the large objects where fish hide.


CHIRP transmit frequency regulated sonar pulses place energy into the water for the long duration. This gadget accomplishes remarkable determination and target recognition by utilizing using digital pattern matching and signal processing. CHIRP (Compressed High-intensity Radar Pulse) is a customary echo sounder that depends on an unmistakable frequency pulse bouncing back off fish or bottom. You can able to identify individual fish and separate fish from the bottom structure is a matter of in inches. Instead, you single mass, you can see individual fish in a group.

CHIRP devices very much capable to transmit both on high and low frequencies simultaneously. The lower frequency gives greater depth penetration with less power consumption than a higher frequency signal generating less noise.

Mounting Options

It is very important to mount the transducer on the boat.

  • Through-hull with fairing blocks offers the best performance, especially at higher speeds.
  • Through-hull flush mounts are best for trailer boats where good performance is required and there are no protrusions from the hull.
  • In-hull transducers do not penetrate the hull but do sacrifice some performance.
  • Trolling motor: Clamped to the outside or permanently installed inside propeller hub of trolling motor.
  • Transom-mount:adjustable-angle bracket is bolted or screwed to the transom, with transducer hanging below and behind hull. Simpler installation, but may encounter more turbulent water flow.

Why should you need a Fish Finder?


The first thought might come to your mind of putting a big dollar on some electronics device on the kayak would be awkward and your money goes into the water with one roll of your kayak. Well, digital colorful screen fishfinders are nice, but you don’t need to spend $ 400 to $ 500 to get what you need. A basic fishfinder can give all the features you are looking for.


You know there might your target fish are hiding place but you can’t see from above water. Those devices allow you to see the water bottom and help you to target specific species fish. For the example bass fish’s favorite hiding place is some sinking structure or swimming area of halibut fish, now you can see their places not only that you can see them also. It will be an advantage know the bottom depth, especially when if you are in an unfamiliar area. If it feels fishy about the area you can come back later to it by getting some land references if you don’t have GPS with you. Examine a couple of land reference points and finding the depth where you can put in that area.


Another reason is to locate bait when it is hard to find bait on the surface. Maybe many times bait laid into the water column and can be located by the sounder. When you unable to get bait at your dependable spot, then your fishfinder will be your only useful tool. If you like to dive those are some of the obvious reason why you should invest in a fishfinder. They are some other features that May or may not apply to your specific needs; like changing the transducer scope, dual screen options.
