Buyer’s Guide: Getting the Best Saltwater Fish Finder in 2023
Fish finders of every category are packed with a myriad of features so locating the one best for saltwater fishing will need more than just basic knowhow about the gadget.
This buyer’s guide will ensure you’ve an idea what the best saltwater fish finder for money should entail.
Fish finder, whether small or large, cheap or expensive, without an adequate display will be a waste of money. An adequate display means the screen is large enough to let you monitor information related to the maritime environment without straining your eyes.
The larger the screen, the easier it will be to read what’s displayed on it and the more information it will carry at once without overcrowding the screen.
However, as the screen size increases, you’ll witness an equal increase in the pricing.
Another factor that can impact screen visibility is the quality of picture. This hinges on the number of pixels. Higher number of pixels means you’ll get a high resolution crisp and bright image.
Also, coloured display is easier to read as compared to a black and white one, not to mention it gives a more true-like view of the underwater world.
Sending sonar signals and receiving data of fish and bottom structure is the job of a transducer so you need to check how powerful it is.
A simple method to check the power is to see how deep it can cast sonar waves. A powerful transducer will allow sonar signals to penetrate hundreds of feet deeper to locate and distinguish between fish, bottom landscape and vegetation, be it in murky water, saltwater or freshwater.
A 500watt transducer will work efficiently for almost all fishing applications.
Frequency is another key factor that needs your attention as it will determine the depth range as well as detail of the information.
A high frequency will not go deeper into water but it will carry better overall detail of the view, even from a moving watercraft.
Lower frequency will work perfectly for deep sea fishing and offshore fishing as the beams can travel hundreds of feet below the water surface to detect targets hovering near the bottom.
However, the image will lack detail. Low frequency is ideal for shallower waters.
A general rule for the frequency you should learn by heart is: the deeper you search, the lowest will be the frequency. Lower frequencies can delve deep and bring better returns.
So, the gist of all is that either pick a dual-beam chirp or low-frequency unit for saltwater or offshore fishing ventures.
Side & Down Scan
Side and down scan provides you better detail of the whereabouts of targets in your vessel’s vicinity as it will cast beams on both sides of the boat as well as below it.
This innovative technology increases the possibility of landing targets whether its saltwater or freshwater fishing.
I can name dozens of fishfinders that are great in every aspect, but their higher learning curve and testing setup suck the joy out of the whole experience. For instance, Elite-9 Ti9 of Lowrance, HDS-12 Live and some high-end units of Humminbird’s Helix series require practice and patience to master their operating mechanisms.
Alternatively, HDS-7 Live is also a high-end, feature-packed unit, but its easy and intuitive interface can blow you away.
In low-end and economical units, Hook2 4X, Garmin Striker Plus 4 and Ricank Portable fishfinders are the easiest to use.
All in all, prefer a unit carrying adjustment and customisation options but with a highly user-friendly interface, be it in a keypad menu or touchscreen format – something that even less-experienced anglers can navigate effortlessly.
Price & Warranty
No matter which features you prefer, at the end of the day, pricing is always a major deciding variable. One general rule I always share with customers asking for help is: if you are a professional fisherman planning to step up your business or a tournament-grade angler, confidently go for a top-of-the-line unit loaded with the latest technologies.
On the other hand, the logical choice for amateurs and occasional users is to pick an inexpensive unit without bells and whistles. You can acquire high-efficiency features even in economical devices. I can give you a few names for reference: Garmin Striker Plus 4, Lowrance Hook2 4x, Garmin Striker Plus 7cv, Venterior VT-FF001 and Humminbird Helix7 Chirp MDI.
Whichever unit you choose (expensive or inexpensive), make sure it offers an arresting warranty program. After all, it’s your money, effort and numerous future expeditions on the line.
Fish finders are acquiring more and more features in order to remain at the forefront in this competitive market.
Features like GPS system and built-in mapping are a must as not only they give you a better sense of directions but also help you find your way back in emergency situations.
They will also help you pin waypoints, routes and favorite fish hotspots to help you conveniently revisit them without unnecessarily meandering around.
You will come across overall great units lacking built-in maps or adequate detail about the bottom topography. In such circumstances, software allowing personalised cartography in real-time or downloaded maps acts as a saving grace. When that’s the case, confirm the unit has storage to house imported maps and other information.
Connectivity features prove really helpful for the import and export of relevant information through navigational apps.
What is the best saltwater fishfinder?
– If it’s about the best offshore fishfinder GPS combo, my top picks are Garmin echoMap 126sv, Humminbird Helix7 Chirp and Simrad Go9 XSE.
– When it comes to a high-end fishfinder for saltwater fishing that is the best overall, nothing can beat Lowrance HDS-12 Live.
– If you want the best affordable fishfinders for offshore fishing, my top choices are Garmin Striker Plus 7cv, Ricank Portable Fishfinder, Lowrance Elite9 and Hook2 4X.
What frequencies should I use for saltwater or offshore fishing?
As a general rule, the deeper territories you fish, the lowest frequencies work the best. Roughly speaking, when your depth exceeds 1500 feet, frequencies lower than 140kHz are your solution. If you are fishing between 600-1500 feet, a frequency range between 80-150 kHz will serve you well.
Remember that the frequency varies in chirp transducers and offers better target detection and target differentiation.
Do I really need a fishfinder for saltwater fishing?
It depends on the depth and size of the water body. You may not need a fishfinder for inshore saltwater fishing because you mostly fish in shallow areas. But, if your goal is to fish in the bottom, deeper water or offshores, you will definitely need a fishfinder with efficient sonar and navigational facilities – one that can perform accurately in saltwater and brackish water.
I always suggest users pick a unit that can function well in more than one type of fishing scenario.
What’s the best way to differentiate between bottom fish and the bottom contour (echo)?
Inexperienced anglers have difficulty distinguishing between the bottom echo and bottom fish, particularly with low-end, primary functions fishfinders. Generally, slightly upgraded models carry a feature in the setting menu called ‘White Line’. Activating it draws a white line right above the bottom contour on the screen. When a sonar return shows the presence of a fish, the echo is displayed in a different colour right above the white line to separate the fish from the bottom echo.
What to look for in the best value saltwater fishfinder?
If you want a little bit of both, i.e. a taste of advanced technology and value for the money without going bankrupt, look for a unit that offers a mix of sonar imaging and screen clarity at a relatively reasonable price.
Low-to-Mid-Range units of Humminbird’s Helix and Garmin’s Striker series have a bunch of both.
However, if you aren’t afraid of becoming a couple of grands poorer, Humminbird Helix 10 G3N and Lowrance HDS-7 Live will give you the time of your life on the water.
Fishing in saltwater will no more seem like an impossible dare if you’ve a best saltwater fish finder on-board. Its improved sonar technology will easily and quickly detect fish hovering near bottom without mixing it with debris and plantation. Above list contains fish finders with varying features and price ranges to suit demands of a wider population of anglers. In order to instantly find the model cut out for your intended uses, the above given reviews along with the buyer’s guide will give you a detailed outline to help you zero in your search to that specific model.
