Bought my e5dsi a couple of weeks ago and have had it out a couple of times now, and I have to say I am impressed. I have it set up on the console and my old traditional sonar on the front. It's pretty cool to see a blob of some sort on my front unit, and by the time the blob gets to the back of the screen, the blob becomes a tree, or a boulder, or whatever on the dsi. The definition is incredible. So much so that I keep seeing my fishing line as I keep casting showing up as a diagonal line across the screen. With all the tips I learned in this forum, I had little trouble figuring out how to operate it. Still a long way to go of course, but way easier having read the forum. Have to say that im a little disappointed in the gps. I'm sure its the same with all of them, but I was in the water on my way out and it had me somewhere in the parking lot of the marina. Same thing on the way in. I drove right into the parking lot "according to the gps", as I was coming in to the dock. I know there are limitations on accuracy set by the government, but really? I was hoping to be able to follow a certain depth contour line when I got my Navionics card, but I don't see how this could be possible. Somewhere in the thread someone said he had downloaded a free map of his home lake that was more detailed, tighter topo lines and history and structure of the lake before flooding. I don't think he said where he got it or if he was able to get it to work. I know this thread has been going awhile, but if there is still any interest, I take some snap shots when I get my flash card. Over all, very impressed with the unit.
