How to choose best GPS fishfinder combo for the money?

Before we look at the features of an underwater scanner, understand why they are beneficial. Why you need one and how can they help? The below are some key benefits that a scanner provides:

GPS fishfinder comboTo find fish easier – Obviously, this is the main point of having such a piece of equipment. An underwater scanner is equipped with advanced sonar and radar capabilities. This allows you to see what is in the water below your vessel effectively. If you fish on a regular basis, a locator will help improve your experience and you will have much more fun. Furthermore, you will catch many more fish than usual.   

To determine numbers – Fishfinders are best used to search for large schools of marine life. When you are out on the water, you can simply go from spot to spot and bag one or two catches. Using a GPS, you can find where there are huge numbers of fish. You can then maximize your time and stay on one spot for increased efficiency. As with the above, your trip will be more exciting and rewarding.

top rated GPS fishfinder comboTo ascertain water depth – When sailing on a lake, river, or even in the open oceans, you have to be wary of the water depth. Even a small lake can have varying depths and seabed that differs by several yards. If you do not know the water depth, you could potentially sail into shallow water and become stuck on the seabed. Moreover, you could potentially crash into rocks and ruin your boat. Furthermore, you can use the depth to uncover what fish are where. Certain species may swim at lower depths, whereas others could stay towards the surface.

To find water temperatures – Water temperature can vary greatly. The base temperature of a lake or river will remain fairly consistent, but it can change depending on the weather and season. Additionally, sea temperatures vary too. Why is this important and how could the best fish finders with GPS help? Simple – the water temperature can affect movement patterns. Different species may prefer warmer water while others prefer the cold. You can analyze the water temperature and become more accurate with your catches.

Saving data for subsequent trips – Most devices allow you to save the scanning data. Let’s say for example, you have travelled to a large lake and found an awesome patch with plenty of catch. You could store the location data, and other statistics using your gadget and refer back the next time you sail on the lake. This is a brilliant advantage of using the best fish finders with GPS.

 

Choosing the best fishfinder for fishing

Now that you understand the basics of these apparatus, we can look at the features to should look for. These include the transducer, frequency, power, screen resolution, cone angle, and portability:

 

The fishfinder transducer

The fishfinder transducerA transducer is what allows the scanner to transmit and obtain sonar waves to display an image. Without a transducer, this device wouldn’t work. A transducer emits sonar waves towards the water bottom. En-route, if the signal hits an object, the radio-waves are bounced back. This is how an image is formed displaying fish and the waterbed.

Consider the transducer material and how it attaches to your vessel. Most transducers are plastic, but some are made of bronze or steel. The type of transducer depends on the material of your vessel’s hull. For example, a fiberglass hull is suitable for a bronze encased transducer.

Aside from the material, look at the type of transducer and finder. There are three main types – standalone, combination, and networked. Standalone is simply a sonar device,  this is the most basic model. Combination models,provide both finding functionality and advanced statistics such as graphs and water temperature. Finally, we have networked models. These are the most expensive and advanced. They connect to other sources via WiFi or Bluetooth to provide live data.

 

Frequency and Power of fishfinder

Transducers have a frequency and power rating. These are two important features of the model. These features have a significant effect on the quality of your display and the sonar image you will receive. It should also play an important role in the overall usefulness of your fishfinder and the enjoyment of your sailing adventures.

Frequency and Power of fishfinderFrequency – Frequency relates to the cone angle of the transducer sonar waves. A model can have varying frequencies. There are generally three categories of frequency designation – single, dual, and multi. Single frequency accessories only operate on one band while dual frequency devices operate on two different bands. Finally, multi-frequency gadgets operate on a range of frequencies.

Common frequencies are 50, 192, 83, and 200 kHz. Higher frequencies work best in shallow waters, whereas lower frequencies work best in deeper seas. It is advisable to purchase a finder with multi-frequency capabilities to give you greater versatility. The Hummingbird 410210-1 Helix, for example, can operate at 83, 75-95 and 175-225 kHz.  

Frequency and Power of fishfinderPower – Power is measured in Watts. The higher the wattage, the faster your display will show information. The power rating you choose will depend largely on the water you fish in. If you regularly go in shallow waters, a higher power rating is not necessary as less power is needed to fire the sonar waves. Alternatively, if you sail on open seas or deep lakes, a higher power rating is advised. As a general rule of thumb, every 100w of power at 50kHz your transducer will work up to a depth of 400ft. The Lowrance Hook-4 Sonar for example has a power rating up to 500W and can operate at frequencies of 455/800 & 83/200kHz.

 

Screen resolution of a fishfinder – Color vs. Black & White

Screen resolution and display quality is integral to the quality of the  gadget. We’ve looked at the resolution and whether you should purchase a black and white screen. The screen quality determines how clear you can see the scan and potential catches.

Screen resolution of fishfinderScreen resolution – When we talk about screen resolution, we mean the number of pixels displayed. Digital screens are made from thousands of individual pixels that form together to create an image. The greater the dots per inch (DPI) and size, the more pixels and the higher quality the display. For example, the Hummingbird 698ci has a 640px x 480px resolution which is fantastic. Ideally, you want a screen that is a minimum of 600x400px if not larger.    

The color of the display –There is more to a color screen than just black and white. A color screen can have a different levels of color display. When looking at the screen color, look for DPI and other info. Some screens may only have a limited number of colors available whereas others display a full range of shades, this gives you greater detail and a more realistic picture.

Color vs. Black & White fishfinderColor vs. Black & White – Some older models still have a black and white display. We strongly advise against this. A color display is much more rewarding. A black and white display is not as high quality, and you will not be able to see as much detail. You can easily obtain a fishfinder under 1000 with a quality color screen.

 

Cone angle of fishfinder

Cone angle of fishfinderWe are not talking about a cone of chips, the cone is the signal arc it creates when scanning. When the gadget scans, it emits a pulse from the underside of your boat/vessel – this forms into a cone shape and gets wider as it gets deeper,  Imagine a traffic cone.

The angle of a cone relates to how wide it spans from the GPS device. This is important because it denotes how much vision you have when scanning the water. A device with a limited cone and a small angle (for example 6 degrees) will have a narrow field of vision and you will not be able to see great deal. Alternatively, an accessory with a wider cone angle should allow you to see much more. Remember the wider the cone angle, the poorer the quality of the display reading. Ideally, a cone angle between 16 to 20 degrees provides an excellent quality scan. Remember this when purchasing the best fish finder under 1000.

 

Portable vs. Mountable

Portability must be considered when looking at a device. Portability and location go hand in hand. Which style you buy depends entirely upon the fishing you undertake. Moreover, it will also depend on the vessel you use:

Portable vs. Mountable fish finder gps combo

Location – So where do you usually try and land a catch? Do you go out on the open waters? Do you go on streams and rivers? Maybe you go on lakes? For longer trips out into the open sea, the best fish finders with GPS should be mountable as you need stability. Alternatively, if you simply travel on quieter waters for shorter periods, you could use a portable fish finder GPS combo.

Type of vessel – What vessel do you usually travel in? Maybe a simple kayak or canoe? Maybe you sit on the side of a lake in your chair? What about if you take a large sailing boat out to sea? For smaller vessels, there is no need to use a mountable attachment – you can simply store it on your boat. Alternatively, if you are using a large ship, a mountable device is prefered.

Frequently Asked Questions about GPS fishfinders 

Having a decent selection of the best and most affordable GPS fishfinders is one thing but if you haven’t had much contact with these devices before, you’re likely to have some questions. To round out your understanding and make sure you’re as informed as possible, we’ve decided to answer a few basic questions people tend to have about fishfinders.

What is a fishfinder transducer?

A transducer is the device that sends sounds waves out into the body of water you are fishing and then receives back echoes of the signal waves. By receiving back those echoes, it can determine what is beneath the surface of the water and at approximately what depth each object is located. The transducer uses data it receives from the echoes to reconstruct a picture of what things are like underwater, including rock formations and fish. It’s this reconstructed picture that is the basis of what your fishfinder GPS displays for you.

What frequency should I use on my fishfinder?

What frequency should I use on my fishfinder?

Fishfinders emit a fairly wide range of frequencies depending on their intended use. Usually, these range from 15 kHz to about 200 kHz, though fishinders that emit frequencies outside this range do exist.

As a general rule, high-frequency emissions are useful for reconstructing detailed and specific pictures of what is going on underwater, but become useless at great depths, while low-frequency emissions are useful for general and broad-based searches, or for searches at great depths. The ideal frequency you want to be emitted will depend on where you plan to fish and the depth and details you require.

It may be a good idea for you to first case out an area with low-frequency pulses (~15 kHz) to get an idea of the general location of the school of fish you are after. Then, you can increase those pulses to a higher frequency to pinpoint a fish’s location more precisely.
