The echoMAP 70dv fishfinder/chartplotter combo offers amazing features on its 7-inch pinch-to-zoom touchscreen. Its built-in advanced HD-ID sonar and DownVü scanning sonar provide the clearest scanning sonar images on the water.

Add SideVü Scanning Sonar

Add an optional GCV 10 scanning sonar module (sold separately) for DownVü and SideVü™ scanning with CHIRP sonar technology .

Advanced Sonar Support

Built-in support for a wide selection of Garmin transducers, including 50/200 kHz and 77/200 kHz. In addition, echoMAP 70dv will support Minn Kota® and MotorGuide® trolling motor transducers.

It allows networked combos to share their internal sonar with any other device on the network. You also have the flexibility to choose what information is overlaid on the sonar screen. For example, time of day or GPS speed.

echoMAP 70dv also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using HomePort™ planning software.

Super-fast 10 Hz GPS/GLONASS

With the integration of a 10 Hz GPS/GLONASS receiver, the 70dv refreshes position and heading up to 10 times per second. It displays constant and fluid on-screen location and proves to be incredibly accurate when marking waypoints and navigating.


echoMAP 70dv offers select networking capabilities that allow you to share features with other compatible echoMAP units, such as DownVü and SideVü scanning sonar, supplemental maps, and user data, including waypoints, routes and tracks. User data entered into 1 chartplotter can be automatically synced with other chartplotters in a network.

Panoptix™ Down Transducer

With 1 Panoptix Down transducer, you get 3 remarkable views, allowing you to actually see fish and bait swimming around under your boat – in real time. You can even see fish in the water column in 3-D, from the bottom to the surface. You can be stationary yet still see things in 3-D below your boat.


Shows real-time moving sonar images below the boat. This screen shows bait drop echo trail movement in purple with sonar history data at left.


Scans the area below the boat from front to back and side to side. This screen shows a school of fish sitting against the back side of vertical face, on Pport side of boat 35 feet deep.


Scrolls through the data as the boat moves to show the history of entire water columns – from the bottom to the surface and all of the fish in between. This screen shows the boat passing over a stream channel with a school of fish between 30 to 40 feet.

Panoptix Forward Transducer

One Panoptix Forward transducer provides 2 impressive views, even while your boat is stationary. It shows the bottom plus fish and bait swimming in the water column in front of your boat – in real time. You can even see your lure as you reel it in. You can also get 3-D views of fish and structure in front of your boat.


Updates are provided with a single ping, providing real-time moving images of what’s in the water. This screen shows a large target (a diver) approaching the boat.


Digitally scans the area in front of the boat, creating a forward-looking 3-D view of the bottom, structure and fish. This screen shows fish targets at 10 feet and drawing bottom depth of 20 feet.
