Although there’s a lot of rivalry with fishfinders, we feel that the Echomap 7​3sv from Garmin is one of the greatest choices. It has a slew of features, also it provides enough customization and performance to work for almost all types of fishermen. Your livelihood is just getting started or whether you are an old pro, you’ll make the Echomap 7​3sv work for you.

Let’s see how it could improve your fishing experience.

Multiple Screen Sizes Available

One reason we like the version is that you just get to pick your size. Most finders have one option available. In this case, you may select out of five, four, seven, or two inches for your screen. If you can’t see well, we strongly advise that you go with either of the larger models.

The excellent thing about these screens (every one of these) is that they provide high definition imaging and a full-color display. They are backlit, therefore you’re fishing during the night or whether the sun is shining onto time, you can easily see everything.

With the larger sizes, you can divide the screen so that you can monitor your location to the GPS (we’ll get into that in a second) as well as view what’s happening below the top. The one thing missing is that a touchscreen capability, but you won’t miss it.

Still another exceptional reason to invest in the Garmin Echomap 7​3sv Marine GPS is the fact that it uses CHIRP Sonar. In contrast to other techniques that are fish-finding, CHIRP is far better because it operates. One signal frequency is only used by Standard sonar. This version sends out sound waves you can get imaging. It also provides clearer and sharper designs for fish.

The other great thing about the Garmin Echomap 7​3sv Marine GPS, specifically, is that it is sold with view imaging and both the side. Fishfinders may only find out what’s happening directly beneath the transducer. But if you want to check at what’s happening around your ship also, it is possible to activate the negative view screen and find yourself a better appearance.

Built-In GPS w/ Maps

Since Garmin produces this FishFinder, you can expect it to own a GPS that is high quality. That the 7​3sv will come with a few extras that make it better compared to the competition.

First, it’s chart plotting and waypoints. This enables you to map your advancement and mark areas having the most fish. The next time you venture out you don’t have to spend as long looking for the perfect spot.
