Thanks for the great echosounder, for a great price and very fast shipping within 24 hours. better does not work. \ r \ nI do not use the sonar in the Elbe you finally recognize what debris and what are fish. very good is the photo realistic representation with the fish finder in the station wagon. \ r \ nNegative it is not a guide, in German , on dvd and what should I do here in Germany with the deposited water map from the USA. \ r \ nDo still I can recommend this device to anyone
