Product Review

GARMIN ECHOMAP PLUS 73SVGarmin is one of the recommended marine device manufacturer companies headquartered in Switzerland. The company has launched several successful products. However, one of them is the Garmin Echomap Plus-73SV .This device has many attractive features. However, the first thing that attracts me towards it is its touch screen display, which is extremely easy to use and understand. This gives the user the advantage of quick changes to the settings. If the hands are wet or the user is wearing gloves, it can also be controlled using the control buttons. It is a user-friendly device, and the user can set the program on the home screen that they use most. The display unit of this product is a 7 inches screen that offers a comprehensive view and detailed information. There is also the feature of adjustable backlighting so that the user can read it efficiently in broad daylight.

The display also provides the split-screen feature that makes it adapted for more than 1 task at a time. The user can also connect the device with the smartphone, and the Active Captain application performs the actions with the phone.

It has a decent sonar that uses the GT52HW-TM transducer. This sonar can be used for 2D CHIRP, ClearVu, and SideVu sonar activities. This transducer can also be connected to a 20 feet cable and 12-pin connector mounted on trolling motors. The sonar system of Garmin Echomap Plus 73SV operates typically at frequencies of 77 kHz and 200 kHz that can be used to cover the angles between 24 and 16 degrees. Thus the high and low frequency allows the user to scan a large or in detail and in my view is a great thing.

The Garmin Echomap Plus 73SV is also capable of the CHIRP feature which works between 150 to 240 kHz. With the help of the CHIRP sonar, more detailed sonar images and more accurate results can be obtained that provide better target separation and resolution. It also provides the features of ClearVu and SideVu sonar systems that use 455 kHz and 800 kHz. The ClearVu sonar system is best used to see the bottom structures that are below the boat. On the other hand, SideVu sonar sends sound waves to the side of the ship, creating a cross-sectional view of the water. It can provide data up to 800 feet in freshwater by using CHIRP sonar, and ClearVu and SideVu sonar have a range of 500 feet.

It also provides navigational support to the user with its LakeVu g3 maps that provide detailed data of 17,000 lakes that are accurate up to 1 foot. Active GPS support also refreshes five times a second to offer trouble-free navigational support. This fish finder is also compatible with BlueChart g2 and BlueChart g3 which are best suited for off-shores. Moreover the user can also employ the lakeVu ultra by upgrading the system.

It is also enabled with chart-making abilities and offers the quickdraw contour feature, which can be used for unexplored areas. This feature employs the GPS and the Sonar to create accurate data with depths. These maps can also be shared with the quickdraw community.It can be connected to the Wifi and has the micro SD slot for additional support.


Display and Control

It has a touch screen interface that is unique because most of the models are button-operated. It also has the control for general features such as power and zoom. It has a 7-inch screen and provides a colored 800 × 400 pixel display.


The sonar of the device is extraordinary, and the GT52HW-TM transducer can produce a wide range of frequencies. It can create 2D CHIRP, ClearVu, and SideVu sonar data with its transducer.
