Fish Finder GPS Combos: Buyers’ Guide
Choose a Screen Size
While many anglers will focus on the features a fish finder and GPS combo offers, these features are useless without the right size and quality of display. You can find displays in a variety of sizes and qualities from 4 inches to 12 inches, with some even larger.
High resolution is important, so try to go with at least 720 by 480, or 480p resolution. Larger resolutions are always better, with 1920 by 1080, or 1080p resolution, being the top of the line for display units.
While larger can be better, you won’t want to be dealing with a 12-inch display screen if you are a kayak fishing angler. In this case, smaller screens can still offer crystal clear views of your fish finder sonar – they simply lack the screen space to add extra details and may involve a few more button presses to get the information you need when you need it (see here for our favorite fish finders for kayak fishing).
For example, on a full-size 1080p 12-inch display screen, you can have multiple views on screen at once from your various imaging sonars in a split screen or 4-box grid, with a vertical sidebar showing water temperature, depth, and other related information.
On a smaller screen, you won’t be able to do that. Instead, you will normally have to switch between slides to see the fish finder sonar view you want at the time, as well as check another separate slide for water details and information.
Choose Other Features: Downscan, Sideview, Active Imaging
The imaging that you choose to go with can depend on a variety of factors including your set budget, the brand of fish finder sonar unit, and the size of vessel you will be using the fish finder sonar on.
Two well-known scanning features are DownScan and SideView or SideScan. This help to give you the total picture of the water below and around your boat so you can easily pinpoint the precise area to troll in order to locate fish.
For example, when using side-scanning sonar, you can see fish and structures a couple of hundred feet to either side of your boat. This will help you determine which direction you should move in order to get closer to suspended fish or schools (see here for our favorite fish finder models with sidescan).
Down scan will give you the picture of what’s directly below you. If you’ve been trolling towards a school, a down scan can let you know when you are right over those fish so you can simply drop a lure right into the water (see here for our advice on how to read a fish finder).
Both side and down scanning fish finder sonar offers a range of clarity, with some of the best sonar offering picture quality imaging and others giving you rough blips and letting you do the educated guesswork in determining just what you might be looking at.
DownScan is an extremely popular and almost required scan for chartplotting which reaches an average depth of 400 feet. Since it shows you not only the contours of the bottom, but also natural and manmade structures that may be there, you can set key points for your journey to return to later such as sunken ships, caves, large coral beds, and more.
Consider Mounting Methods for Your Boat
Ensuring your sonar has a good and solid mounting spot is important for getting the best view on your display. Many sonar units will include mounting hardware, but some will not and it will be up to you to decide not only the type of mount you want but the best one for that particular sonar unit.
Mounting your fish finder is easy (see here for tips and instructions), and will simply require a suitable spot on the helm of your vessel or the support bar on your portable vessel for kayak and canoe anglers. However, mounting the transducer is where problems can start to arise. Mounting it too close to certain vibrations, near the propeller, or near the water jets can distort or even completely ruin the imaging.
Gimbal mounts are extremely easy to use and are great for small crafts such as kayaks, canoes, rafts, dinghies, RHIBs, and more. You won’t need a permanent mounting spot for a gimbal and can instead move it around as you see fit throughout your trip.
Transom mounts are the most popular options but can be somewhat tricky depending on your engine since there can be some interference if the transducer is installed too close to the propeller, water jets, or vibrations from the motor itself.
Another thing to keep in mind with transom mounts is that you will need to secure the unit below the waterline which may require drilling holes into your boat for the mounting brackets. Instead of doing this and risking damage or future leaks, you can also look into hole-less mounting plates which use waterproof adhesive for safe and secure, long-lasting mounting.
Consider Compatibility With a Trolling Motor
Like outboard motors, trolling motors can sometimes cause interference with your transducer. Not only that but some trolling motors are installed in the exact spots you would normally put a transducer, leaving you to find an alternative spot for your fishing sonar.
Additionally, some sonar can interface with your trolling motor, letting you adjust the speed and plotted chart directions on the fly. The trolling motor will automatically make adjustments on that speed and direction while you are away from the helm tending to your fishing rods in the water.
Fish Finder GPS Combo: FAQs
Which Fish Finder Is Easiest to Use?
While this will depend on what you are hoping to achieve and what you expect in a fishing sonar, Lowrance takes the cake with their Hook2 series as one of the best fish finder GPS combos on the market today.
This marine electronics sonar is not only affordable but offers autotuning sonar frequencies and no learning curve. The user interface is easy to navigate and simple, giving you more time to enjoy the views.
Which Fish Finder GPS Combo Has the Best Mapping?
Almost every higher-end fish finder GPS combo sonar model in the Humminbird line has extremely high-end mapping capabilities, chartplotting abilities, and waypoint systems.
If you are looking for an included library of maps showing lakes, rivers, reservoirs, and coastal areas, Humminbird can provide that. Their Apex model offers more than 10,000 preinstalled charts which can get you started on some epic adventures on the water.
For more info on mapping packages check our articles on Lakemaster vs Navionics maps and Navionics vs C-MAP maps.
Which Fish Finders Do the Pros Use?
While this will again depend on what the pro in question prefers from their fish finder GPS combo fishing sonar, the Lowrance HDS Live 12 has been rated one of the most popular fish-finding imaging sonar for professional tournament anglers to date.
When asked why they love the HDS Live 12 so much, many anglers will say it’s due to the extreme clarity and details of the imaging on the massive 12-inch display, as well as the enhanced mapping and Navionics with more than 4,000 preloaded enhanced maps.
Is Sideview Important?
For anglers that spend a lot of time in open water or deep areas, such as large lakes, reservoirs, or the ocean, side view is not going to be top of the list when it comes to important features. That would be where you want your down imaging to shine and take the cake in performance.
However, if you spend a lot of time fishing in shallow water such as rivers, coastal areas, bays, and more, side view can be a vital component of your fishing setup. Side view helps you find fish that may be highly active or flighty, as well as those that stay in the topwater areas of the lake or river.
How About CHIRP Sonar?
While many anglers swear by their 2D traditional sonar technology, Compressed High-Intensity Radar Pulse or CHIRP technology is a very useful upgrade when you want a clear view of exactly what is around you.
With standard 2D traditional imaging sonar technology, you may see a large blip and wonder if it’s a massive fish or a slowly sinking log. With CHIRP, you’ll be able to clearly see what it is and even see the rate it is sinking at.
Many modern fish finder units offer both 2D and 3D imaging so you will have the option to choose which you like better. But in most cases, having CHIRP is better since having more detailed information is never a bad thing.
