Query: Rangefinder Capabilities

The Celestron Oceana 7x50 overall is a great set of binoculars.Pros:-Great optics-Built tough-Built-in Electronic Compass-Attached Lense coversSuggestons for improvement:-Rangefinder scale needs better resolution (more lines)-Documentation should include formula as to what each scale line translates to in distance or object size (such as MIL or MOA)-Focus should have common adjustment for Left and Right eye pieces (this model requires that the Left and Right eye pieces be individually focused)
