Optics
 
Nubie here with optics need a little help . what's the numbers x numbers represent?

jjfuller1 02-08-2013 02:09 AM

Adjustable zooms, and lens size.

A 3x9x40 is a scope that can adjust from 3x zoom up to 9 x zoom and the lens is 40mm.
A 4x32 is a scope permanently set at 4x zoom and has a 32mm lens.
And the list goes on
2x7x40
4x12x44
6x16x50

Often larger lenses are better at dark or low light conditions.

This is a good explanation of the basics, there is a lot to scopes but this is a darn good start.

A good rule of thumb:

The scope should cost about the same as the rifle it's mounted on.:)

Why???

What does matching price points of two entirely different products accomplish?

You can't shoot what you can't see. And you can see a whole lot better with nicer optics

that is true. however, there are a lot of GREAT scopes for a 1/3 or even a 1/4 of what the rifle they end up sitting on costs. it really depends on magnifacation,clarity, and desired usage.

That is very true. Nikon is a great example of that

This is true enough but, it still doesn't explain why a scope should cost the same as the rifle.

Well would you rather have a TC Encore and put say a Nikon Buckmaster 3-9x40 and go hunt and have to go home at 6 because its getting to dark or would you rather put a Zeiss 3-9x40 for 400 more and be able to hunt out until 7 or so? That's just the way I see it. Plus they are more durable and dependable when you are at full magnification, they won't be as fuzzy. They utilize the rifle to its full potential
