good point. i have a 727 on my current boat and i like it just fine. it replaced an eagle 320 after it rained and filled with water. might have been a fluke but a 9 month old fish finder shouldnt have it was not damaged, so I went with a different brand. (no more lowrance for me) so far i have been happy with humminbird. I got the weather sense for 6 dollars in december. its kind of cool to know what was going on when the fish turn on or off.
