Buyer’s Guide

Fishfinder is an exciting tool that has made fishing much more productive and added a lot of fun to it. A variety of fish finders is available in the market, and it’s not easy to choose a single model for you. This guide contains all the essential points one must keep in mind before buying a fish finder.

Transducer

A transducer is the most critical part of a fish finder because it is responsible for sending beams that return to it. It translates these signals to provide you the detailed information about the underwater structures.

Transom mount transducers are handy and are easy to mount. Most of the fish finders come with this type of transducers. For professional and demanding tasks, thru-hull mounted transducers are also available, but the installation is complicated.

You will find single, dual, and multiple frequency transducers, from which dual-beam sonar is most common. They work on different frequencies ranging from 90 kHz to 200 kHz. The cone angle is directly related to the frequency beam. The higher frequencies show up more details and perfect for the shallow waters, while small frequencies will work great in deep waters.

It is recommended to buy a fish finder featuring dual beam sonar as it will offer both small and large frequency options making it useful in both deep and shallow glasses of water.

Display Quality

The size and resolution of the screen is another crucial factor to consider when buying a fish finder. The screen resolution is the number of pixels your screen has. Higher the number of pixels higher the screen resolution. The quality of images is entirely dependent upon the number of dots your screen has.

For example, many inexpensive models come with a screen resolution of 240v x 160 h, which is the minimum resolution required to get some readable details. As the resolution increases, the images become sharper, more detailed, and super crispy. Fishfinders with higher resolution screens are expensive, and they are specially designed for professional purposes.

The reflective screens are another big problem, decreasing the readability in bright sunlight. Anti-reflective coatings on-screen are best to go out on sunny days. The backlight LED also improves the readability of the display and is ideal for low light conditions.

The size of the screens is measured diagonally and is an essential feature of the fish finder. It ranges from 3.5-inches to 8-inches. The inexpensive and portable units have smaller, while bulky and expensive units have larger screen sizes.

GPS and Mapping

GPS and mapping is an important feature of any quality fish finders. Many inexpensive models do not have GPS support, but today, many brands have equipped the fish finders with GPS technology. These models are available at affordable prices.

The GPS feature allows you to create maps of the underwater terrains, send the locations, create and save waypoints. This information is kept and can be used in the future. You can also navigate easily and can download the pre-designed maps to get the ebay information available.

Transducer Material

Transducers are available in different materials and each of them serves a unique purpose. The plastic transducers are good if you are using the fish finder for recreational and gaming purposes. These transducers come with a transom mount and are easy to install.

Professionals need a transducer featuring an in-hull mount or thru-hull mount, which means you will need plastic housing for a metal or steel hull. A bronze housing is perfect for a wood hull.

These transducers are not easy to install and you can only install them if you have proper guidelines regarding the mounting process.

Angle of Beam

The beam’s angle depends on the transducer’s frequency and can range from 9-degrees to 60 degrees.

As the beam goes down, it becomes wider and covers a larger area but sensitivity decreases. Some expensive Fish Finders come with transducers that can emit multiple cones at multiple depths giving you extra details.

It is better to get a transducer that can emit a beam between 16-degree to 20-degree-as 20 degrees is a sweet spot for many anglers.

Power

Power is an important feature that tells the accuracy and sensitivity of your device. A fish finder with high wattage will scan deep, and gives quick details as compared to the one with low wattage.

For example, a unit with 100 watts at 50kHz can scan down upto 400 feet; from here, you can know how much power unit you should buy. The expensive units have more than 1000 watts and can scan deep down, for bringing precise, quick, and brief details.

Water Resistance

Water-resistance ability is vital for fish finders to withstand the water environments and rainy seasons. T water-resistant fish finder is less prone to damage if it gets in contact with water.

There are some water-proof units also available. Most of these units have a waterproof rating of IPX7 and can bear the rainwater, water splashes, and quick immersion in freshwater.
