Had the 570 DI since March this year. Have never been able to get it to work right. From what I read on this site, I'm not the only one. Have the range jumping issue. Will read correct depth then go to 72 ft or something else or will flash 572 or something else. Have tried the suggestion of setting the "surface clutter" to 3 and setting "water type" to fresh even though I live on a salt water creek with the water depth from 2 to 10 ft.

I would like someone who has a working 570 with good DI display to PLEASE post there 570 DI settings. This would give me a great baseline for troubleshooting my unit before I contact Humminbird or buy noise filters or special power cables.

Thanks for any help!
