I've been following the discussions and posts on this site for some time, and have seen very little posted on the Ifinder. I am curious as to why no one uses Lowrance equipment. I own a GM100 and an Ifinder; these units have never failed me in any way and the Ifinder has many new features that the GM100 didn't, i.e., expandable memory. The only thing I wished the Ifinder has that it doesn't is Auto routing. Garmin V has this, but Garmin V does not have expandable memory. Please let me know your thoughts on Lowrance equipment.
