Hi, Welcome to my Best Fish Finder Reviews! Firstly, I would like to share my guide on choosing a fish finder. As we know a fish finder consists of several parts, some of which are really essential to ensure the unit work out the best result. And there are more reviews waiting for you, click here to skip this guide and grab reviews.

This guide will try to cover the various technologies, reading this guide, you should have a good idea which one best suits you in your mind.
There are several factors to consider with the display.
Obviously the larger the screen the better, if your budget allows. It’s easier to read from larger screen and larger ones will provide more detail. Especially when you choose a Fishfinder/GPS Combination, the screen size factor is even more important as the Fishfinder and GPS often share the same screen
Screen resolution is usually expressed in a vertical and horizontal pixel count, of course, the hight pixel count the clearer image the screen displays. If you fish in deep water, the resolution will be very important.
Color or Mono?
If your budget allows, go for color ones. It’s much easier to interpret what the fish finder is telling you. Well, mono is OK, too.
A fish finder won’t work without a transducer. If you are not clear whether a fishfinder comes with a transducer, you should always ask. There are several types of transducer you should know.
Transom mount transducer – This is maybe the most common. The transducer mounts on the back of your boat and contacts well with the water. For smaller fishing boats, this is typically the best solution.
Thru-hull transducer – as the name implies, this transducer mounts through the hull. The advantage of this kind of transducer is it will not be subject to cavitation interference caused by the motor and hull of the boat when it passes through the water. This type of transducer is generally used on relatively larger boats, and typically more expensive than a transom mount transducer. In addition, you may also need a faring block to protect the transducer. Temperature and speed are available with this type of transducer.
In-hull or Shoot thru hull transducer – this type is not so common. This transducer actually is mounted inside the boat and emits sound waves through the hull. It’ll need some experience to use it well and it’s expensive.
This is a parameter indicates how powerful the sonar is, measured in watts. This is especially important in deep water, because the higher the power is, the more power a fishfinder has, the stronger the return signal is. On a fishfinder, there are two ways to display sonar power – Peak to Peak and RMS. Peak to Peak is 8 times of RMS.
Dual Frequency and Single Frequency
A single frequency fishfinder transmits its signal at a frequency of 200khz and gives you a relatively narrow view. A dual frequency fishfinder transmits signal at 200khz and 50khz, you will always get the possible view of the water under your boat, whatever shallow water or deeper water. A dual frequency fishfinder usually is not too much expensive than single frequency one. If you choose a dual frequency fishfinder, please also be sure that the transducer is also dual frequency.
Well, I think this article has covered most of buying a fish finder. I hope you find this fish fider buying guide helpful. Now you can click here for some fish finder reviews, catalogrized by brand.
