I just got rid of my X-85 and bought a Garmin 160 from cabelas for 150$. The Lowrance cost around 400 if I remember correctly. In my opinion the Garmin is a much better unit, much more sensitive. It will show my buzz bomb at 80 feet down. The Lowrance rarely even showed my downrigger balls, and lots of times it wouldn't show fish when there lots of them down there. I haven't noticed the problems with Garmins that I have read above. Fine shallow water performance and rare interference problems.
