What do the two numbers such as 8x42 mean?

The first number is magnification, so 8x makes a subject appear eight times closer. The second is the objective lens diameter in millimetres, which affects brightness and size.

What magnification is best for general use?

8x is a versatile choice, offering a wide field of view and a steady image that is easy to hold. Higher magnification brings subjects closer but narrows the view and shows more shake.

Do I need waterproof binoculars?

Waterproof, sealed models resist rain and internal fogging, which suits UK outdoor use. If you mainly view in dry conditions, weather sealing matters less but still adds durability.
