2. Marcum Digital Handheld Sonar


2.MarCum Digital Handheld SonarEven though it is slightly less affordable compared to the unit we have showcased above, the MarCum is definitely worth having a look at.

This handheld sonar system has a power of 2,500 watts, making it the right choice for people who want to fish both in shallow and in deep waters. The model can offer depth readings up to 299 feet.

Unlike other devices in the same line, this one has a series of features that are pretty hard to say no to.

For example, the 12-cone angle and the oversized top-mounted LCD display make it one of the most popular varieties out there. Yet another noteworthy reminder of the excellent performance of this unit is the 6V lithium battery, which can work continuously for approximately 20 hours.

One of the reasons the battery of the MarCum variety is so long-lasting is that the sonar system automatically shuts off when it is not being used. This helps prolong the overall life of the device and of the battery.

Buying guide


If you’ve been wondering about which the best handheld sonar system is, we’re here to help. We’ve put together a short and informative buying guide to assist you in making the right choice. Whether you want to purchase new or used, the most important aspect to consider is that you should correlate your needs and preferences to the features of the device you’re looking for. Here are some core details to consider.

Handheld sonar system



Power is a matter of great concern when it comes to buying the best fish finders. If you usually fish in shallow lakes, high frequency is more important compared to power. However, if you plan on using the system in deep, murky waters it might be better to pick a higher wattage. The golden rule, in this case, is the more power, the better.


Battery life

Some models can be used for up to 20 hours at a time while others have to be charged after just 7 hours of use. Battery life should be a factor if you’re keen on the idea of going out on fishing trips, where you extensively use the system.



Warranty is a manufacturing brand’s way of respecting its customers. Our advice to you is to pick a product that is covered by at least 1 year of consumer warranty.

2. Humminbird 409700-1 541 Fish Finder


2.Humminbird 409700-1 541 Fish FinderCompared to the alternative we’ve showcased above, this one is considerably more affordable. Normally, a low price does not necessarily mean low quality.

The fact of the matter is that this is a monochrome sonar which does not address the needs and requirements of advanced users.

Some of these individuals might not be willing to wreck their entire budget over buying a unit, regardless of its specs.

Buying guide


Looking for the best fish finders out there on the market? If so, you’ve come to the right place. We find great pleasure in giving out a helping hand to prospective buyers, which is why we have put together a short buying guide. Remember to consider your needs and preferences before buying a certain model. If your time allows it, go over some sonar reviews.

Humminbird sonar


Power and frequency

If you plan on fishing in shallow water, power isn’t all that important. Yet frequency is. The higher the power, the better. With frequency, things aren’t so easy as to say that one type is great for all waters. 50kHz might be the right choice for deep waters, whereas 200kHz is great for shallow lakes.


Screen size and resolution

Gone are the days when fishfinders came with screens similar in size with the ones of old cell phones. Nowadays, we recommend buying a unit that has a screen at least 5-inch wide.

The minimum resolution that you can use to actually understand what’s going on under the boat is 240 by 160 pixels. Anything lower than that will make you focus on interpreting the image instead of concentrating your efforts on the actual catch.



3 Best Sonar Systems (Reviews) in 2023


It’s not easy to find a premium sonar system, as the best ones don’t come with a tag that says they are of top quality and should be purchased by consumers.

Buying guide


One can’t find the best sonar system without investing some time in reading and research. This helps the potential buyer get familiar with the specific elements that determine the ability of the device to assist anglers. To find the fish and hopefully make the season’s best catch, these aspects are what you want to check out in a sonar.



Generally quantified in watts, the power of the best sonar system is an expression of the measurement parameters of the AC voltage total swing from the peak negative to the peak positive value. To describe the output power of the device’s transmitter, experts use the term peak-to-peak (PTP).

Sonars are also evaluated using RMS or root mean square, which denotes the DC voltage that can create an identical heating effect matching the AC voltage. Fishing in considerably shallow water will demand high frequency and less power. Conversely, greater power is required when fishing in greater depths with murky water.



Just like the best fish finders, the sonar system has to be equipped with a powerful transducer that provides the cone angle and operating frequency needed for successful use in the water. Serving as an antenna, the transducer sends out sound waves that get returned to it as echoes. The transducer unit can be mounted inside the hull or on the transom of the boat, or to the trolling motor via a special mounting kit. For large fiberglass boats, a true thru-hull option is ideal.

Consider the type of fishing usually done to help decide on a suitable cone angle.



The display is an essential aspect of any marine GPS unit. Detail is a primary factor, followed closely by pixel. Crude and blocky images result from fewer pixels, while smooth curves, lines, subtle nuances in structure plus thermocline comes from more pixels. In addition, check out devices with high contrast and high resolution.

Some models have straightforward basic displays, while others can be used with a smart handheld device such as a smartphone for viewing of images.
