Recently installed an 898 and a 596 on my boat. Read through the manuals and took the boat out to play with the units and set them up. It was then that I ran into a question that I need an answer to. In the manual it says there are 2 frequencies that the side imaging can be ran at...either 455khz for deeper water or wider field of view or 800khz for more detail. While playing with my 898 i noticed my 2 frequency options are 455khz and 262khz...no 800 like the manual says. The 262 is basically useless..no detail to speak of. Does anyone have any idea why my unit would not have the 800khz option? Do I need an update? My unit is new..just recently bought. The manual says the 800khz gives the best detail and touts that fact more than once, so I'm going to feel cheated if I can't get that frequency on my unit. Has anyone else had this issue? Humminbird Greg..if you read this would you please find out what's going on here and post a reply? If I don't hear something back on here I'll call HB support and see what their remedy is. Thanks
