Thanks Greg. I Guess thats why i couldnt find it on the 1158. I have the 1198 on the console and the 1158 up front onthe trolling motor. I cant seem to get the settings right on the 1158 to get the quality of display I Expected. I had Anticipated with dedicated DI It Would be Awesome as I Had a 798 or 788 and it was amazing. What freq. Etc.would you reccommend for starters on the 1158. It is approx. 3 months old and has not had any updates in that time. Thank you in advance for being such an active and sincere contributor to this board.
