Humminbird 899ci SI HD


2.Humminbird 409150-1 899ci SI HD Combo Fish FinderThis model is a little more affordable than the aforementioned one. It comes with a smaller display, but 7 inches isn’t that small after all, is it? The display is color and backlit and does a great job at showing readings even when the sun is up.

This is called a combo because it comes with its own GPS, chart plotting, side imaging, down imaging and a dual-beam sonar.

Believe it or not, this is one of the most powerful fish finders we’ve come across, as its wattage is a whopping 4,000 watts.

The device has Ethernet networking capabilities and comes with a transom mount transducer.

It comes as no surprise that the unit has managed to gather some of the most exceptional side imaging fish finder reviews. Customers speak highly of the device’s dependability and sturdiness, as some state they’ve had issues with other brands in matters of air-tightness.

Lowrance Elite-5X HDI


3.Lowrance 000-11143-001 Elite-5X HDI FishfinderWe’ll start by saying this one is by far the cheapest side imaging fish finder we’ve come across. It’s affordable yet it doesn’t lack quality. Sure, its screen size is a little smaller compared to the devices we’ve already described, but that is to be expected since it can be bought for a much lower price.

The 5-inch display is a color LCD that has a 480 by 480 pixel resolution, thus speaking to the needs of people actually looking to see their catches.

The display is backlit and can thus be used in the middle of the day and in case you feel like doing some night time fishing.

This is strictly a fishfinder and can’t be considered a chartplotter. Its official description doesn’t mention anything about a GPS, but if you already own a separate device, this is the right one to go for.

It comes with a dual imaging sounder and downscan imaging.

Buying guide


If you’ve been looking for the best fish finder, you’ve come to the right place. For your consideration, we have put together a short list of things you need to consider if you want to make the right call. Always remember that your needs and preferences have to come first whenever you’re making a purchase, which is why you need to read as much info as possible.

A lot of details such as frequency, wattage, size of the screen, down and side imaging contribute to picking out the right model. Just have a look at what we think is most important.




Screen-related features

Even with side imaging fish finders, screen size matters quite a lot. If you pick an older model that’s cheap and somewhat old-fashioned, you’re likely to purchase one that comes with the screen size of an ancient mobile phone. It might do a good job at providing accurate readings, but you might have a little trouble understanding them.

Resolution and color are two other factors to consider. The higher the resolution, the more detail you’ll be able to see. Color-screen fish finders can help you to better understand the underwater environment. Units that feature grayscale displays are usually destined for people on a tight budget.


Frequency and power

The same goes in the case of both of these specs. The higher they are, the better. Actually, in the case of frequency the matter might be a little more subjective than you could be tempted to think. A frequency of 200 kHz will get you great readings in shallow water, while one of 50 kHz is perfect for seeing your catch in deep waters. Some modern models come with customizable frequencies, which gives users the freedom to pick the right one.

The more watts, the merrier the user. Extra power is synonymous to faster readings and crystal clear images.



Basic fish finders are perfect choices for beginners, but most buyers tend to specialize in their craft. Sooner or later, they’ll start looking for more advanced models. All things considered, one of the most acclaimed feature of these devices is downscan/down imaging, which is best combined with side-imaging. Down imaging allows buyers to visualize picture-like images, while side imaging helps them understand what’s happening around the boat.

For example, some models are capable of providing readings which result from scanning the area up to 240 feet on both sides of the location of the boat. That sure comes in handy, doesn’t it?
