How a Fishfinder GPS Combo Works and Why Use One?

Fishing can be a sport of waiting and watching intently, but what if there was a way to minimize the amount of searching that you had to do? Well, there happens to be a device that does just that. A fishfinder GPS combo works by using a transducer to find where the fish are and navigate you on any body of water with ease.

The conical transducer identifies where fish are located by sending out pulses that use echolocation to target movement. Fishfinders and GPS are superb visibility tools that allow you to see what’s above and below the water. If you’re in the market for one of these devices under $1000, then check out this buyer’s guide.


Choosing a Quality GPS Fishfinder Under $1000

Mounting Type/Material

You should keep in mind where you want to mount or use your fish finder. Some of the fish finder GPS combos on the market are available as handheld units. These models are nice for finding a fishing hot spot and then setting aside and casting. 

Casting fish finders feature small transducers and are meant to be tied to your fishing line for casting. They usually lack their own display screen but instead send an image to your mobile phone. These models are waterproof and submersible.

The last mounting option is boat-mounted. These fish finder GPS combos can be mounted on your boat. They feature different transducer types, such as through-hull, transom mounts, and shoot-throughs.

Transducer

This device allows a fishfinder to find where the fish are located. The cone angle and number of beams determines how well a fishfinder will see fish and the contours of the floor. A single cone-beam with 50 degrees or more will show you a large area of fish but not the bottom of the seafloor.

A single cone-beam with 10 to 15 degrees will show you a small section right below the boat that will pick up fish and the seafloor. We recommend a dual-beam fishfinder, which combines a high-frequency beam to show great detail and a low-frequency beam to show wide features.

Display

There are a few things to consider for your next fish finder GPS combo display. Resolution is determined by the number of pixels that are illuminated on your screen. The more pixels per square inch, the better you’ll be able to see details of things below. You’ll find many different resolutions in the products below, but they range from 480 to 1080 pixels.

Another important factor is the screen size, which ranges from 3.5 to 12 inches. Usually, higher-resolution devices are more expensive, but we think it's worth it. You should consider if you want a colored or backlit screen to assist with viewing. Backlit displays will help with the glare of the sun.

Scanning Sonar

There are two main types of fishfinder GPS combo sonar frequencies; CHIRP and traditional sonar. The traditional sonar has served anglers well over the years. It emits a static frequency pulse that listens for echos to return. The newest technology is called CHIRP sonar. It emits a wide range of frequencies to pick up images better.  

Signal Strength/Frequency

In general terms, a fish finder that operates at higher frequencies will perform better than lower frequency devices. High-frequency pulses will have shorter wavelengths with more pulses. Low-frequency pulses have long wavelengths with fewer pulses per second. Multiple frequency bands will also increase the performance and give you a better image.

Water Resistance

Almost all fish finders have some water-resistant properties. The IP rating is the measurement that we use to determine a device’s waterproof level. Most fishfinders have an IP rating of IP-X7, which means they have been tested against accidental spills and heavy rain. This rating also indicates that a device can be submerged, but only up to 3 feet for 30 minutes.

Depth Range and Target Separation

Simply put, the depth range is the level at which your fish finder will find targets in the water. Most of the devices on our list have a depth range of up to 5000 feet. Target separation is the ability of your fish finder to separate different objects underwater, such as fish and landmasses. 

Performance Features

Certain features will enhance the performance of your fishfinder, such as display and scanning speed. Your fishfinder display should have anti-glare features so that you can see in direct sunlight. It should also be viewable from multiple angles. You should see how many times your fishfinder sends out a signal. This will affect the amount of fish that you can see.

Ice fishing requires different gear than regular fishing, which can sometimes be challenging to find. We chose the Humminbird Ice Helix 7 as the best marine GPS fishfinder for ice fishing. It is similar to the previous Humminbird model but designed specifically for ice fishing.

The Humminbird Ice Helix 7 comes with two display modes that enable you to see exactly the details that you want at any time. The CHIRP sonar system provides real-time feedback on fish and lure presentations.

It comes with six settings to reduce interfering sonar signals. It gives you a clear view of either sonar or flasher mode.

Cheap vs. Expensive Fishfinder Combos

Every angler likes a good bargain deal, but what is considered too cheap that you'll sacrifice quality? Some cheap fish finders will produce lackluster images with poor target separation. More expensive fishfinders have quick scanning CHIRP sonar that provides images quickly, so you don't lose track of a target. The fish finders under $1000 in this buyer's guide are all high-quality, so you can expect a long-lasting device.


Comparing CHIRP to Traditional Sonar

All of the fishfinders that we have reviewed in this buyer’s guide feature CHIRP sonar. This is the newest in fish finding technology. Most notable companies are switching to using this method in their transducers.

Traditional sonar transmits only about one percent of the time. On the other hand, CHIRP sonar sends out ascending pulses that last ten times longer. They put about 10 to 50 times more energy into the water.

Microprocessors interpret the subtle differences in fish below the boat. You will get much clearer images with CHIRP sonar. It also provides excellent target tracking capabilities.  Another notable difference in sonar imaging is ClearVü and SideVü. With ClearVü imaging, you will get a picture of what is directly below your boat.

With SideVü imaging, you will get a clear picture of what is happening on the sides of your boat.

Down Imaging vs. Side Imaging

There are two main types of imaging that modern fish finders produce; down and side imaging. While they may seem self-explanatory, there are some key differences.

Down imaging sonar produces an image that shows you directly beneath your boat. These types of fish finders work well when fishing in deep water environments for tuna, swordfish, or red snapper. Down imaging can produce clear images even at relatively high speeds. The disadvantages of down imaging include lower resolution and less coverage.

Side imaging provides you with clear images of both sides of your boat. They allow you to look more quickly since they provide data on both sides. They generally offer a better view of the water when fishing. Side imaging fish finders are more expensive, but they work better for finding fish in shallow bays and creeks. This includes fishing for trout and bass.


How to Use a Fishfinder GPS Combo

Now that you’ve chosen your new device from the list above, you’re ready to get started with using it. Follow the steps below to start finding fish and catching them.

  1. 1
    Always read the manual before operating your new fishfinder.
  2. 2
    Mount the fish finder to your boat. Depending on the model that you have selected, you will need a mounting bracket and the appropriate tools. The transducer will need to go on the tolling motor, ide, or through the hull of your boat.
  3. 3
    Power on the fishfinder. Most fishfinders will come with some preprogrammed settings that you will need to work your way through. Some of them are simple such as the date and time. Other settings will be about the fishing environment.
  4. 4
    Adjust the sensitivity. If you’re fishing in shallow water, then you should adjust the fish finder to a higher frequency. If you’re deep-sea fishing, then you should set it to a lower frequency.
  5. 5
    Set the fish ID setting according to the type of fish that you are hunting.
  6. 6
    You should leave your auto-depth setting to detect depth automatically.
