I recently purchased an Elite 4. It has GPS but is not the DSI. I am very happy with the GPS. The graph I'm still getting used to. Although this maybe because I have never used one before. I'm very happy with it. My next purchase wil be a sonar w/out gps, with a bigger screen. Maybe an elite 5. I fish Maumelle most times. It is no problem finding the fish shelters. If you are going to Camp, you can check it out.
