Powered the unit up it passed self test and everything. Have been hearing a lot about trolling motor interference so i wanted to check and see if I had any. So I dropped the Xi5 and hit the prop button and let me tell you it was like the 4th of July :bang head. Trolling motor interference in a big way. This was never an issue with my 597 even with the 597 snd my 999 running at the same time I never had any type of interference. The noise filter on the unit is on high 3 and it helped the 2d image so but not at all for the DI image. So I took it to the lake anyway thinking well at least I could still see my brush in 2d and it is a new unit so I wanted to play around with it. 1st spot on my 999 where I known there is brush because it is a DNR brush pile. Brush shows up as all way drop marker moved to the front trun on the 859 and nothing I could just make out the bottom Picture looked like well you know the 4 letter word. Even turned off the 999 to make sure there was no cross talk. I am very disappointed in this unit at this point. If I can not get it fixed I will be going back to my old 597 and someone will have them a 859 with 5hrs on it. I know this is a lengthy explanation but someone please help!!!!!!
rf. noise can be really be a pain to get figured out.u can fix your issue tho..ive run the 597hd/di unit, with transducer mounted on motorguide digital tour with very good results and now have an onix10 with transducer mounted on an motorguide xi5 and still get good results.i use no chokes / ferrite rings.i do have skeg grounded tho.(Humminbird makes a trolling motor choke that some say works).I don't think there's anything wrong with your unit.Those filter settings, u mentioned. I've never had much luck with them.For me, the answer was sending the noise to ground in the water.good luck with your units.(u can stop the rf.) Keep in touch with rickie,he'll help get u going☺☺☺
