You’ll find this particular unit on the majority of Garmin 73sv reviews currently available.

You’re an enthusiastic angler, right? In that case, wanting a better view of the underwater is not asking for too much. After all, our curiosity lacks boundaries, right?

Table Comparison: Garmin 73sv & Alternatives

Important Factors to Take Into Account When Buying a Fish Finder


All you have to do is go through these features to know how to choose the best fish finder.

1. Frequencies

Never fail to take the invaluable frequency range into consideration. The three different types of ranges are multiple, single, and dual frequencies. These include 200, 192, 83, and 50 kilohertz (kHz).

The higher values are suitable for shallow water. While the lower frequencies are ideal for fishing in deep water! When frequency is higher, the fish finder offers more detail on screen.

2. Power

Here, you’re looking at the wattage of the unit. With a higher wattage, you get a faster response time. It even offers a deeper view of the underwater. So what does this mean? It implies that you can work with less wattage when fishing in shallow water.

Now let’s combine the wattage and frequency range. In that context, 50 kHz range per 100 watts power provides readings that are 400 ft. deep. Hence, 240 kHz per 100 watts will give you a reading up to only 100 feet.

3. Screen Resolution

Without high resolution, nothing looks better anymore. Especially when using electronic devices! So you need something that’s 240 by 160 pixels at the least. There are models with a higher resolution as well. It all depends on your preferences.

As for the size of that screen, you can opt for a smaller version as your backup. Since you might not use it so often!

4. Transducers

The transducer feature is what’s responsible for finding fish. It emits and receives sonar waves. And these alert you when fish or any other objects are present nearby. Once the transducer receives this data, what happens? It transfers the information to the primary unit. And then to the locator’s screen. But without a transducer, you’re only looking at a fancy display without any data.

5. Screen Color

Colored high-resolution screens have now become way more reliable. As compared to their black/white counterparts! The former is easy to view and read even in sunlight. But it’s the latter that you can buy as your backup.

The thing about such Garmin 73sv reviews is that they provide you with all the information you need. So now let’s move on to the Garmin echoMAP CHIRP 73sv with transducer!

An Overview of the Garmin 73sv

Now it’s time for me to present the echoMAP CHIRP 73sv. Here, you’re dealing with a 7-inch wide screen. And resolution of 800 by 480 pixels! This delivers a superior viewing field from all the angles. Even under bright sunlight!

As for advanced technology, the device features CHIRP sonar. This particular functionality sends nonstop signals at a single time. On both high and low range scale! So the unit has the ability to fire many signals at your target. As a result of which it provides more accuracy when it comes to frequency returns. (Understanding sonar technology)

Moving on, here’s another exceptional component. It comes in the form of LakeVu high-definition maps. These provide you with high-detail information. From more than 17,000 rivers and lakes in America!You get twice as more data with LakeVu than you would with any other finder currently available.

What’s also enticing is the remarkable Quickdraw Contours element. For you to create your personalized maps! And these Garmin saves to the device automatically. Moreover, there’s the GPS technology that ranks among the most popular. The navigation system is both reliable and accurate. So much so that it refreshes your position at least five times every second!

Even tasks like installation and mounting are very easy. For the latter, Garmin provides various mounting solutions that fit your every demand. So the echoMAP CHIRP 73sv is an outstanding device. Especially if you want to transform your entire fishing experience!

LakeVu High-Definition Maps

When you get access to preloaded lake maps, the activity becomes quite pleasant. But what makes it even more appealing is when these preloaded maps are as many as 17,000. Out of which, 5,700 contain contour lines of 1 foot. This eliminates the cost and effort of buying extra mapping cards.
