The ECHOMAP Plus 74sv is one of the new Garmin fish finder and chartplotter combos for 2018. As opposed to the older echoMAP CHIRP 74sv it has several extra features, such as a cross touch interface (touchscreen and keypad), and has built-in Wi-Fi. It’s similar to the ECHOMAP Plus 73sv that we’ve previously reviewed here, but this particular model comes with the U.S. coastal charts and a different transducer. For reference, this is the Garmin part number 010-01898-01.

Sonar & transducer
The ECHOMAP Plus 74sv features three main types of sonar: traditional 2D CHIRP sonar, ClearVü, and SideVü. It includes the new CV51M-TM transducer which supports all these three types of sonar. This transducer has 30′ (9.1 m) of cable with a 12-pin connector. It features a transom mount and has a built-in temperature sensor.
But nonetheless, the unit is compatible with other transducers, such as the CV52HW-TM (12-pin), or the CV51M-THP. Also, this Garmin unit is compatible with the new Panoptix transducers.
According to its capabilities, the CV51M-TM is a transducer for off-shore fishing. For the unit’s traditional sonar it uses a CHIRP pulse modulation between 80-160 kHz, in other words, Mid-Band CHIRP. The Mid-Band CHIRP beam is conical, with a coverage of 24°-13° and a depth capability of 2,300 ft (701 m). However, this depth capability is for freshwater. In saltwater, this system’s depth capabilities should only reach 1,100 ft (335 m).
For ClearVü and SideVü, the transducer uses thin, fan-shaped beams. It’s capable of two main frequencies, 260 kHz and 455 kHz. The CHIRP modulation intervals are 245-275 kHz and 445-465 kHz. The beams are approx. 2° fore to aft, and approx. 29° @ 455 kHz, and 51° @ 260 kHz. The system’s max. depth capabilities are approx. 1,000 ft (305 m) for ClearVü, and 750 ft (228 m) for SideVü. These depths are also calculated for freshwater. In saltwater, the system’s structure scanning sonar may not be able to reach these depths.
The unit is capable of using dual-frequency sonar and transducers with such capabilities. For example, it can use transducers that operate at 50/200 kHz or 77/200 kHz, with the ability to use both beams simultaneously.
Among the unit’s standard sonar capabilities, we can count Fish Symbols, Amplitude Scope, Flasher View, Bottom Lock, several alarms etc. The unit offers Sonar Recording and Sonar History Rewind features which give you the possibility to have a second look to a scanned fishing spot, without the need to re-scan it. It also provides traditional sonar support for Minn Kota® and MotorGuide® trolling motors with integrated transducers.
As we’ve mentioned above, this unit is intended for off-shore fishing. Therefore, it comes equipped with the BlueChart® g2 for the U.S. coastal waters. They cover the West Coast, the East Coast, the Gulf of Mexico area, and the U.S./Canada side of the Great Lakes. They are based on official charts and also include other information such as nav-aids, spot soundings, depth contours, tides information and more.
BlueChart g2 Charts
Evidently, the unit is compatible with various other charts from Garmin, such as BlueChart g2 HD or BlueChart g2 Vision HD. Also, in case you want to use it for inland fishing, the LakeVü HD Ultra is also an option. However, just as most other Garmin units, this one is not compatible with charts such as Navionics or C-MAP.
Like most other 2018 Garmin fish finders, the ECHOMAP Plus 74sv has the Quickdraw Contours feature. This allows you to map the lake or body of water where you’re fishing, revealing its depth contours. It uses the 2D sonar information and the GPS navigation, giving you the possibility to create your own personalized maps.
The SailAssist feature base is also available with this unit. Among them, we can count, laylines, enhanced wind rose, heading and course-over-ground lines. They can help you gain a wind-maximizing edge, give you the possibility to see true and apparent wind angle and speed. A pre-race guidance page shows you the virtual starting line along with data fields showing laylines, time to burn before the start and the race timer. Plus, the unit supports AIS and VHF radio units. It does not support Radar, though.
The ECHOMAP Plus 74sv is equipped with a 5 Hz internal GPS. It delivers 5 position updates per second, and can also calculate the speed of your boat. The unit can store up to 5,000 waypoints in its memory, and up to 100 routes. It can plot your track, being able to record up to 50 tracks, with up to 50,000 points for each track. Any track can be saved and converted into a route to which you can add waypoints.
Control unit features
Since it’s a 7x unit, the ECHOMAP Plus 74sv features a 7-inch diagonal display. It’s a full-color unit, with a pixel resolution of 800H x 400V and LED backlight. Its new interface combines touchscreen technology with keypad navigation. In other words, you can control it as a tablet, or, in case you’re fishing and don’t want to get the screen dirty, you can use the keypad on the right side.
The unit’s interface is very easy to use. It gives you the possibility to customize your home screen with the most used applications in order to access them quickly. Also, there are several split-screen options available, with up to three applications per view.
The unit is IPX7 waterproof. This means it can withstand incidental water exposure or rain. It can also take immersions in freshwater.
As opposed to the last year’s 74sv, this one offers Wi-Fi connectivity. You can sync it with your tablet or phone, in order to get smart notifications. You can also connect with it online to directly access OneChart for software updates or map downloads, and more.
The unit is equipped with a microSD card reader featuring one card slot that can take cards up to 32 GB. It has NMEA 0183 ports and also supports NMEA 2000. It also has a Panoptix all-seeing-sonar port.
There are two mounts included with this Garmin unit, the classic U-bracket mount with the quick-release system and surface mounting kit. The box also includes a unit cover.
