Bausch & Lomb 9x25 Legacy
To get more information on the B&L 9x25 Legacy you can call Bushnell at 1-800-423-3537. They may have an instruction manual available, but it will likely not be specific to the 9x25. Their manuals tend to be general "one size fits all" instructions that cover the basics of focusing and so on.
Traditionally the Bausch&Lomb label has been reserved for Bushnell's better line of optics. When the 9x25 Leagcy was a current model, one feature that set it apart from the Bushnell line was the fact that it had multi-coated optics for better light transmission and therefore brighter images.
Your B&L Legacy 9x25 is a reverse porro prism design, similar to the Nikon Travelite. Indeed, the 9x25 legacy was designed to compete price and feature-wise with the Nikon, and as such, is a dandy little compact. The eye-relief is only fair, but this is an issue only if you wear glasses when you observe.
Like the Nikon Travelite, your 9x25 is weather resistant, but not waterproof, so use a little caution in extreme weather.
The 5 on the focusing knob indicates your binocular has a 5 degree field of view. What this translates to in practical terms is your binocular has a field of view at 1000 yards of about 263 feet, since each degree is equal to 52.5 feet at a thousand yards. A field of view of 263 ft at 1000 yards is average for a compact binocular of 9x magnification.
All in all, your Bausch&Lomb 9x25 Legacy is about as nice a compact binocular as you will find in its price range. Enjoy!
