Ricky,promised follow up!
Ricky , Since you were the only one to offer help. Here is what I have tried. Went today, started the day with straightened transducer. 2D was 0.k.DI was still almost non existant. Would go for periods and could not see ANY down scan. I have seen great screen shots on this forum. I haven't seen any on my unit. I did a factory reset and it seemed to play a little while ,then bottom went away and I got NOTHING. The unit is very warm???. I tried both transducers and did not see any major difference.The only thing that I did not try was a soft reset. DI has got to be better on other units or they wouldn't have sold so many. Paid a lot of money (about $700) and I just want it to work like it is supposed to or like some of the ones I have seen on this forum Unless you have some other suggestions. maybe it is time to call Lowrance. I don't know if I would cough up enough cash for another HDI with chirp. (maybe a Garmin Echo 551 dv) At least making the transducer square with the bottom solved the crazy depth problem. Thanks for your help......crappie1133
