Some of the best marine VHF radios come with GPS functionality which may be important for our readers and for water activity lovers.
Watch The Transducer
The transducer that will go onto the bottom part of the boat is important to see. The concern though is that not all fish finders come with their own transducers. This does not mean that a fish finder cannot work well without a transducer.
Even the main unit you get can still work by producing its own signals into the water. But you would have to watch carefully for how well a transducer might produce stronger signals.
The transducer should be made with sturdy steel material so it does not break off quickly. Plastic might be cheap and easy to set up, but it could also break apart fast if you are not careful enough with it. Also, a transducer should come with a body that can retract or fold off temporarily in the event it comes across any solid materials in the water.
See How Well You Can Adjust It
The fish finder with GPS models always come with plenty of frequencies. You should look at how well you are capable of adjusting your fish finder based on the frequency you want to use or how far the transducer will move. Anything that makes it easier for you to find what is out there is always worth having.
Physical adjustments are just as important. Look at how well you can tilt or turn the unit after you have mounted it onto your boat’s side. Anything that lets you position the finder without having to remove the base is always worth having in any situation.
Battery Power
Most of the fish finders you will come across require battery power for them to stay functional.
A good battery will provide you with enough energy for keeping the unit running for hours at a time. Sometimes the battery is rechargeable, but in most cases, it will simply use traditional disposable batteries that you will supply on your own.
Check on how such a fish finder might work for a longer trip you wish to take, but be sure to bring a good source of energy with you just to be safe.
Wattage Points
Review the wattage on your fish finder. This refers to the amount of power that the finder will get. This wattage is produced by the battery used on the inside. When there is greater wattage, the finder will respond faster and give you more detailed results in as little time as possible. But at the same time, a unit with a higher wattage total might take up far too much energy and battery power.
A good point to see entails measuring things based on every 100 watts of power based on the frequency you use. If you are using a fish finder at 50 kHz, you would read things about 400 feet deep for every 100 watts you use.
For a 200 kHz setting, you will read the water from 100 feet deep for every 100 watts. Be aware of this when figuring out how well the readout is laid out and that you have a good plan on hand for handling the unit.
Resolution
Although the screen on your fish finder could be large, it needs to come with a good resolution rating so it is not hard to see what is on the finder at a given time.
You must have a fish finder that is at least 240 x 160 pixels in resolution. This should give you enough pixels to help you distinguish between different items that your fish finder will identify.
But even with that, you should still at least look for something that produces readouts you can actually identify. You might need to get something with a better resolution level attached to it if you are unable to actually read what is being produced on the screen.
What Do You Want to Find?
Some fish finders are made exclusively to help you find fish and nothing else all that elaborate. Some other models come with features that let you find where the floor of a body of water is or any underwater plants. The type of underwater floor is simply helpful especially when we are thinking about how to anchor a boat properly.
You might want to stick with a fish finder that focuses on fish above all else if you just want to find them. Meanwhile, a more detailed fish finder that lists information on other items is best if you plan on going out to more advanced sites.
Review the Price Versus the Boat
It might be better for you to buy a cheaper fish finder if you have a smaller boat or a kayak to work with. The more high-end options, particularly the larger choices, are best if you have big vessels that cost a little more.
The key is to avoid getting something that might be too massive or otherwise offers more features than what you might actually be comfortable with.
How Big Should the Fish Finder Screen Be?
Naturally, you would want to find a fish finder with a screen that is easy to read. You should only look for a model that is not overly complicated or hard to follow through.
The screen should have a convenient design with enough overlays or sections that you can quickly distinguish from one another.
Map Functionality
Some fish finders work with outside map programs that let you program different routes, waypoints, and other features. A few come with controls where you can save particular spots on the GPS layout in real time.
But when looking at the map functionality, you should see that you can get all your map data points linked up to a microSD card or something else you can use for getting your data secured properly.
Check on the Installation Point
You should be able to install the fish finder you get just well enough. A quality fish finder has to be easy to affix onto the bottom of your boat for the best results. You can always use a clamp or other series of fasteners depending on the model you use.
But regardless of what you have, watch for how the wires are utilized. The wires that go from the monitor to the transducer should be easy to link up and use. Anything that can link to the body of your boat without hanging off or possibly getting loose or caught in something is always worth using.
Brands to Consider
You can find many good brands when looking for a quality fish finder. These include Garmin, Humminbird, and Lowrance.
Garmin has been a popular name over the years thanks to how it offers quality GPS devices. Garmin combines both the features of a fish finder with a GPS unit to help you find fish in even the toughest spaces.
The setups that Garmin offer even let you save many routes, waypoints, or other spots that might be valuable to you. These include some places that you might want to return back to depending on how your trip is moving along and if you can find fish in certain spaces.
Humminbird is a company that has been producing quality fishing maps for years. These include maps that are produced through GPS signals. These maps can combine well with a fish finder tool from the company to help you with finding fish in the right spots.
Many of the models Humminbird makes include options that let you find fish in larger spaces. The setups that Humminbird uses for getting its devices organized are all worth looking into for when you need help with getting around any large lake in the United States or Canada.
Lowrance offers marine and fishing electronics with a focus on sonar devices. The company has been in operation since the 1950s and continues to be a trusted provider of quality marine and fishing units for all kinds of purposes. The designs that Lowrance offers for various fishing needs are worth looking for.
Weight
The overall weight of your fish finder should be checked well. A typical finder should weigh about two or three pounds on average. This is the combined weight for both the receiver and the transducer.
Cable Length
The cables on your fish finder should be a few feet in length if possible. Check on how long the wires are versus the size of your boat so you have an appropriate layout to work with.
Can It Resist Water?
Your fish finder should be able to resist water and wind among other threats. The housing needs to come with a secure and watertight body to keep moisture from moving into its circuits. This is to keep the unit from being too hard to utilize.
It is even more important for the fish finder to protect a microSD card that you might add to its body. A good cover can go over the card slot, thus keeping the card from being exposed and it will save the card from the possible risk of harm from excess water among other threats that might get into your unit.
Display
Color displays are used on a majority of fish finders. A color display is perfect for how it offers a convenient layout that lets you identify many things inside the water. You can use this to find warm and cold temperatures based on the plants, fish, or other items that might be found in a certain space.
Varying shades of blue might also help you identify how deep the water is or how it might be changing in how fast it is moving or what its temperature might be like. Every piece of information is important for the fishing plan. Our winter fishing tips can be a field of interest for many.
This does not mean that a black and white screen is not good enough. You can always use a black and white screen to see what is in an area while reviewing the intensity of each tone to see what is near or what might be moving. This would require a little more concentration for finding something, but it at least works quite well.
Button Controls
The button controls you can use on one of these units should be explored well. A great layout should come with a body where the buttons are easy to distinguish and give you enough of a control setup for making it easier for you to get something to work right.
Loading Times
The loading time on a fish finder should be explored based on how long it would take for the finder to identify where the fish in a spot might be located.
In particular, the loading time can be around a few seconds on average. This should be enough to give you an accurate layout without forcing you to wait for longer than what you can afford to.
Frequently Asked Questions
What causes one of these fish finders to produce its readouts?
A combination of a transmitter and transducer is required to get your fish finder to work. A transmitter is the monitor or another head item you will use while the transducer is a material that goes into the water and is mounted onto the bottom part of the boat.
The transducer will produce signals that move into the water and will identify the echoes that come back as data for what is inside the water.
What frequency should be used?
The frequency that a good fish finder GPS machine can handle should be something that fits in depending on the specific space you want to go fishing in. You will need a 50 kHz frequency if you are going out to a deeper body of water. 200 kHz is best when finding something in shallow spots. The 83 kHz frequency option typically works in the middle.
A higher frequency of around 200 kHz works best when you are inland or in freshwater conditions. It is also suitable for lure tracking.
The 83 kHz setup or something around that works when you are in a larger or more wide-open space. It is not as detailed, but it does give you a better range of view for finding fish.
The lowest 50 kHz frequency is for when you are in deeper spots. This is especially when you are in waters more than a thousand feet deep. A low-frequency setup will identify more items deeper in the water and may work for darker conditions or for saltwater among other cloudy spaces.
What is the Chirp Sonar Feature?
Compressed High-Intensity Radiated Pulse or Chirp sonar is a popular modern choice to look into when finding the perfect GPS fishfinder combo. This uses signals with varying levels of frequencies.
The pulses produced by the sonar are also a little longer in length. This is a desired feature to find in fish finders because it produces clearer signals that are a little more distinguishable and easy to figure out.
How deep does the finder have to get into the water for it to work?
You don’t necessarily need to get one of these fish finders to go far too deep into the water for it to work. You just need to get it supported on the bottom of your boat. It can stick out by a few inches or maybe even a foot.
All you need is enough of a protruding spot to allow the finder to see things in a local area while allowing its waves to move around many spots.
Does the software on your fish finder have to be updated?
Some fish finder models come with software programs that can be updated. These are often updated based on map settings and for any new upgrades that may be utilized.
Although you do not have to necessarily link your fish finder up to a computer to update its software, it does help to at least do it a few times here and there. This is to provide you with a better experience through a stable software program that is easy to utilize.
Can you adjust the speed of your transducer?
Many fish finder models let you adjust the speed of the transducer to let it move a little slower or faster. That is, it rotates at a different speed to produce varying sonar signals.
It is best to turn it to a slower speed when you are looking for larger pools of fish. It can be faster when you zero in on an area where the fish might actually be at. Review the settings on your transducer to see how it works.
How cold can the water be when using your fish finder GPS Combo?
Every fish finder is different in terms of how cold the water can be when you are trying to find fish through it. You must look at how well the fish finder can work based on how chilled the water might be. The good news is that many fish finders are made to work even for ice fishing considerations.
Remember that a fish finder should come with a readout that includes details on how cold the water in a spot is. The temperature readout can help you see what the conditions are like so you have an idea of whether the fish might be dormant in a spot or not. Remember that lots of fish will not move around all that much when the temperatures are too cold.
Can you add the transducer into the water when ice fishing without having to use a boat?
You have the option to cut a hole into a sheet of ice and then inserting the transducer into that hole while the main readout sticks out from above the ice.
But you would have to watch carefully as the wires for the transducer might be small. Also, you would have to use a fish finder that can actually handle the cold temperatures in a spot.
Can anything get in the way of a GPS readout?
It is very easy for a GPS unit to read the information on what is in the water at a given time. But you might want to watch for how well that GPS unit can target satellites in space.
Anything that covers over the GPS unit will keep you from getting an accurate readout. The GPS sensor must have a clear view of the sky if it is going to work well enough.
Will a fish finder assist you with finding certain patterns?
A great fish finder will have a readout setup that lets you identify items within a few inches apart from one another. This is vital when you are trying to find schools of fish or other sizeable groupings.
You can even use this to see if there is a certain formation that the fish might be trying to enter into. You might see the fish getting into an attack formation or just in a form where they are going to move at a consistent speed.
Is an after-market transducer best?
Although the transducer that comes with your fish finder might work well for you, it never hurts to see if an after-market model might work a little better for you.
An after-market transducer might offer a faster readout and can work with more area in a spot. It could also work in more water conditions, particularly in colder or warmer spots.
You would have to look at how well an after-market model is capable of getting onto your fish finder though. It should come with enough wires that can link up to your finder and create a consistent connection.
Anything that can connect well without creating any loose wires that could easily come apart is always worth having.
Conclusion
You will need to look around to see what is available when you are trying to get the best fish finder GPS combo for your use. A great model can help you with not only seeing where you are but also with finding fish in any spot.
The things that can be found in one of these fish finders are diverse and can help you with finding fish in deep and shallow conditions alike. Make sure when finding one of these units that you have a choice that fits in well with your efforts or plans for fishing the right way.
Don’t forget to look at how well the fish finder is designed and that you have something that you can control. The versatility of a fish finder is appealing, but it should also be something that you can quickly adjust and control on your own.
