I finally pulled the trigger and purchased an HDS 10 and I must say that I am impressed. I have a bird 997csi (which will be for sale shortly) but have always felt that the 2d was woefully inadequate. Boy was I correct. The HDS holds bottom at 53 MPH and even gives you a clear crisp display of the bottom at that speed. I was truly impressed. I am just now waiting on the structure scan to be released. Except for the side imaging (which I will withhold judgment until I see the HDS'), the two finders are the difference between daylight and dark.
