The echoMAP 55dv is a Garmin Chartplotter and Fishfinder which features a 5-inch high-contrast display with automatic backlight adjustment, tilting for operability and keypad control for easy use. Preloaded to the echoMAP device are UK, Ireland and North West mainland Europe coast maps. The Garmin 55dv will always update your position on the map display using the built-in 5Hz Internal GPS; In fact it updates your position and heading 5 times every second resulting in a fluid display of your route taken.

The echoMap is compatible with transducers that use both 77/200 kHz HD-ID and Garmin DownVu/SideVu.You willl need to buy a Garmin Transducer for the Sonar to operate.

There Garmin echoMAP 55dv will display views under the water using the built-in Sonar which provides 500 W (RMS) HD-ID/4,000 peak-to-peak. The two ways it displayed images show the view below your boat called DownVu. DownVu will show photographic images below the boat. The display will show structures below the water, submerged objects and fish. For the Sonar to work you will need to separately buy a transducer.

Alternatively, if you know which transducer your require (we do however recommend that you complete our online form to find the perfect transducer) you can view the comprehensive range of transducers available buy from ActiveGPS.

With the echoMAP 55dv you can also record sonar images for playback on a computer using HomePort planning software.

The maximum depth whereby you can use your echoMAP 55dv sonar is:
