Blurry Bushnell Scope

[feet-down]

Hey guys, I have a bushnell 3x-9x sportview scope. I went to do some shooting yesterday and noticed that the target was blurry when the scope was set on 6-9 powers. 3-5 powers were normal. The reticle was clear but I could not get a clear image of the target on 6-9 powers. I know this is a cheap scope but does anyone have any ideas as to what is wrong? Thanks so much. Ryan
