With such a focused viewing, escaping your trap will become absolutely impossible even for the smartest of fish.

2. Humminbird Helix5 – Best Affordable Chirp DI G2 Offshore Fish Finder
A bargained model by Humminbird, the aristocratic class of fish finders, is like a complimentary meal by a high-end restaurant. Meaning, no one will ignore such a golden chance. Humminbird Helix 5 410220-1 is that “complimentary meal.”
The screen is just 5” large, not as big as the previous Garmin model, yet it’s arguably among crowning features of the unit because it can be split in two halves to get data of dual frequency at once without compromising readability.
The shrinking size of screen doesn’t seem much of a loss when its sonar provides you a crisp picture of what’s happening in surrounding waters on the same screen through side and down imaging.
The DualBeam Plus offers a limited coverage of 600ft and 300ft for down imaging which means the unit is not cut for deep oceans, only for freshwater or shallower water bodies.
Whether high-tech or low-tech, any gadget with a complicated running procedure is a big no. Fortunately, this doesn’t come with that hair-splitting and bewildering setup and operating system.
You’ll be able to set it up for action in just a few minutes even as a beginner.
Pros
- Compact and portable gadget.
- Portable model.
- Inexpensive
- Coloured display offers crystal clear image.
- Split screen doesn’t compromise readability.
- Uncomplicated installation and operating procedure.
Cons
- Appropriate only for shallower water.
- Performance is compromised in tidal waters.
Final Verdict:
If you’re on a budget yet want a relatively high-end fish finder with some bells and whistles, then consider Humminbird Helix 5 410220-1. It is compact but still offers bright display along with accurate side and down imaging, making it one of the best portable side imaging fish finders for offshore.
3. Lowrance Hook2 4X – Top Pick Overall Offshore Fish Finder
We all want to reach the hidden cracks and crevices of selected water territory to ensure our boat carries at least one successful catch, if not many, upon returning towards the shore after day long of fish hunt.
Lowrance Hook2 4X makes sure you get a fruitful getaway without putting a hole in your pocket.
Beginners and mid-level anglers get attracted to this model like opposite poles of a magnet because of hassle-free set up and use. It features auto-tuning sonar and phone-like buttoned keys that help you set it for actual chase without wasting time on tweaking with settings.
Coming towards the chasing weapon, sonar coverage, it’s undoubtedly the most distinguishing characteristic of this model because you’ll rarely come across a model of this class carrying such a wide sonar coverage.
In simple words, despite the unit’s small size it allows you to monitor a vast area at once.
But -and here we come to a less ideal part- the low pricing also results in shrinkage of screen and size, available in just one size.
The brighter side, literally, is that the screen is SolarMax so you’ll receive a clear image, bright enough to be easily read even in sunlight.
To top it all, the package includes a bullet transducer that you can mount in different positions to get more intelligible results.
Pros

In a sad state we should warn you that this isn’t a multi-functioning fishfinder-cum-chartplotter like some of the above models so it doesn’t have preloaded maps.
