The Navigator is a downgraded version of Steiner’s famous Commander marine binocular (see Commander 7×50,×50/). Its image is not as contrasty, bright and brilliant as the Commander’s and has less FOV, but the Navigator costs less than half. When using the Navigator on land, it’s a pity that the individual focusers turn so stiff; of course, for a marine binocular that may not be so relevant because at sea, you almost always observe at infinity. Just don’t believe Steiner when they tell you the focusers are stiff because you never really have to use them after a first setup for your vision, and the rest is then done by autofocus. THERE IS ABSOLUTELY NO AUTOFOCUS WHATEVER in the Navigator, we have thoroughly inspected it. Take the Navigator for what it is: a decent middle class binocular with individual focus.
