Garmin echoMap 70dv combines excellent sonar used on the echo series with the Garmin’s brand new DownVu technology, 10Hz GPS receiver, and a brilliant, touchscreen display. The echoMap 70dv has it all and is one of the finest fishfinders we have come across in a long time.
The echoMap 70dv comes with the dual-beam 77/200 kHZ transducer that provides down imaging capability as well as traditional sonar output. Down imaging can be used for identifying structure while 2D sonar is used to locate fish. The output is seamlessly relayed back to a bright 7″, touchscreen display, which makes it a joy to use. The echoMap 70dv can also provide side imaging with the use of an optional GCV blackbox. The 500W transducer can reach the depth of 1100ft in ideal conditions. The sonar output can be displayed in split-screen mode in multiple different configurations. The unit provides water temperature as well as speed and supports the bottom lock feature.
The echoMap 70dv is not only a fish finder, but also a chartplotter. The GPS receives updates 10 times a second which gives it great accuracy fluid display. Garmin offers the echoMap 70dv is three configurations: no preloaded maps, inland lake maps called LakeVu or BlueChart G2 coastal maps. LakeVu is a relatively new cartography product that provides maps of 17 thousand US lakes. The GPS memory can store upto 5000 waypoints and 100 tracks. The unit has 2 micro SD card readers – one can be used for additional cartography and the second one for saving waypoints. There are 2 NMEA 0183 input ports and 2 output ports, NMEA 2000 is not supported. Garmin echoMap 70dv comes with all the necessary accessories. Included are: the transducer along with the transom and trolling motor mounts, bail and flush display unit mount kits, power cable and the protective cover.
