The Garmin echoMAP 50dv has a 5-inch display, which provides VGA-quality imaging. Built into the echoMAP 50dv is Garmin’s trademarked High-Definition Identification target tracking technology. Better known as HD-ID, it provides a super clear image of the area under the boat. Garmin echoMap 50dv combines HD-ID with the DownVü scanning sonar, which provides a virtually photographic view of structure in the water.
The built-in GPS receiver on the Garmin echoMAP 50dv has a speed of 10 Hz which allows it to update position 10 times a second. The higher update frequency results in more fluid boat movement display. Also included is sonar-recording capability for coordinating the timing of the sonar return with your boat’s position. You can playback your sonar recording on a PC with HomePort software or send it wirelessly to an Apple device equipped with BlueChart Mobile software.
The Garmin echoMAP 50dv comes pre-loaded LakeVu HD map package, which provides details of 17,000-plus US lakes; or the BlueChart g2 coastal map package. The 50dv is capable of storing up to 5,000 waypoints and 100 routes. It also has a track log capacity of 50,000 points, with 50 saved tracks. The unit is equipped with two microSD cards for expanding the built-in flash memory and additional cartography. Garmin echoMAP 50dv comes with the transducer, power and data cable, tilt and swivel mount, flush mount, protective cover, and a user manual.
