i have a 788 hd di, and have a question about the dual beam ducer. according to the book, it has 83, 200, and 455 settings. all i have on the menu are 200 or 455. hoe do I get 83/200?
455 would be the DI, and the 83, 200 would be traditional sonar. You may not have a dual transducer. If you do it would be in the main menu under sonar.
