Fish Finder Buying Guide
After having a grasp on the best fish finder reviews, there are still more factors to consider when it comes to the best fish finder on the market. Below is detailed information about this device, giving you more ideas, before ordering one from a dealer.
- Size – The size of the screen is a major factor to consider. Many owners highly recommend getting a finder with a big screen, as long as your budget allows you to. This is more so when it comes to a fish finder, and GPS combo as the two will share a single screen. The best fishfinder with a big screen will allow you to read easier, giving more details, while making it easier in determining what your device is trying to imply.
- Color Versus Monochrome – Fishfinder enthusiasts usually advise you to get the color variety. It is mainly because monochrome screens will only show you between four and 16 various shades of gray for the intensity of the sonar return, while the color screens will show from 64 up to 256 colors of the sonar return. Therefore, having the color variety is easier to interpret, helping you identify the bottom, whether it is soft or hard, with gravel or rocks, and so on. After all, color screens are the biggest advancements in the best fish finders for a long period.
- Resolution – A device with a higher resolution is always better. This simply means that high resolution equals better detail and information displayed on the screen. Hence, it is calculated in pixels, so, this product detail is among the ones to watch out for.
- Others – Based on the model, a fishfinder can also display on its screen more details like the temperature, depth, distance, speed, fuel consumption, navigational information, battery condition, and so much more.
The transducer is a must-have in every color fish finder. It is the one emitting and receiving the sonar signal while sending it to the device itself. It is very important to take note that any of the best depth finders will never work without the transducer. However, there are some fishfinders on the market without a transducer, so, asking is always sensible.
After learning the basics of the transducer, it is now time to identify the kind or type of transducer that you might want to have. Below are the most commonly produced and used transducers.
- Transom Mount Transducer – Transom mount transducer is the most common kind of transducer today as it mounts on the back (transom) of the boat away from its motor. However, it still makes good contact with the water. Typically, this is the best resolution for small fishing boats as well as pleasure crafts. Small fishing boats usually measure not more than 25 feet. Also, keep in mind that some of these transducers can adjust to a trolling motor, while it is used in front of the boat with a trolling motor.
- Thru-hull Transducer – This type mounts through the hull. Among the benefits of this transducer is that the thru-hull is not subject to cavitations interference, which is caused by the motor of the boat and the hull as it passes throughout the water. Larger fishing vessels make use the best depth finder with a thru-hull transducer, including boats that draw plenty of water, commercial vessels, sailboats, and so on. This transducer is usually more expensive than the transom mount type.
- In-hull Transducer – Also called a shoot-thru-hull, this transducer type is the rarest. It is mounted in the boat, shooting through the hull. Among the three kinds, this is the most expensive, although the user cannot obtain the speed or temperature with this transducer.
Note: The majority of manufacturers design their devices to work with their transducers and transducers are rarely interchangeable.
Among the factors to consider, while in search of the best fishfinder is the multi function display. While it is one of the newest advancements, it is a rising trend within the industry as this feature offers multiple functions. A multiple function display allows the user to have a screen display with additional components such as a radar, antenna, GPS, sounder, and many other navigational and sonar needs in one display.
Single Versus Dual Frequency
Fishfinder reviews would explain that fishfinders with single frequency will transmit the signal at 200 kHz frequency. Single frequency finders provide a narrow view of what is underneath the boat. However, it is not a bad thing in shallow water, but you will see less as it gets deeper into the water.
On the other hand, the dual frequency finder can transmit signal at 50 kHz and 200 kHz. In fact, this is designed to whatever frequency the user is in, allowing the best view possible. Some models can show a split screen of the 50 kHz and 200 kHz frequencies.
It is important to compare fish finders when it comes to the frequency. Thus, it is essential to bear in mind that the price of a dual frequency finder is just a bit high, compared to a single frequency. Perhaps, having this unit will be worth the extra cash.
Furthermore, take note that a dual frequency finder should also come with a dual transducer. Today, there are specific models of the top fish finders that can transmit at certain frequencies than what has been explained above.
Sonar power is the measurement of how powerful the sonar is, and is calculated in watts. A fishfinder with a higher sonar power is said to be better. More sonar power also means a stronger signal return, especially when it comes to deeper water. As long as your finances allow you, it is always sensible to get a device with the highest power.
Manufacturers of fishfinders and fishing sonar reviews list the power measurement in two ways – Peak to Peak, and RMS. Peak to Peak is 8 times RMS, such as a 500 watts RMS is equivalent to 4,000 watts Peak to Peak. Some manufacturers list the measurement in both units.
Meanwhile, lower power fishfinders usually have 50 up to 150 watts, while higher power finders may have between 300 and 500 watts RMS. High-end models may have 1,000 up to 3,000 watts RMS. But, the average power of most fishfinders is measured at 250 up to 500 watts RMS.
In a nutshell, it is very important to keep in mind that the top fish finders function similarly, sending out sound waves through the transducer. The sound waves can encounter targets, reflecting the sound waves back and then shown on the screen. The details on display include fish, the structure, and other information about the bottom.
Determining what is the best fish finder largely depends on the features of the device, including the brand as you pay for the quality, durability, accuracy, and efficiency all at the same time. Looking for the best fish finder under 300 or 200 is always essential as long as you keep the key points mentioned above while shopping for the best fish finders for the money. Considering the product reviews and the contributing factors will certainly help you arrive at the best choice possible.
