Large diameter lenses gather more light and improve the optical performance of scopes.
These improvements are a brighter image and better clarity.
Unfortunately, large diameter lenses are always fitted in large diameter housings.
For accurate shooting, scopes need to be centralised inside the peep sight. Large diameter scopes are hard to align because you can not see the housing.
This could be costing you points!
If you were to simply use a bigger peep, you would loose clarity. The Ten zone utilizes a reduced rear housing, allowing easier centralising of the peep, while offering all the benefits of a larger diameter lens. High quality, multi coated optics offers excellent brightness and clarity.
Water repellant, anti static, anti-reflective. You name it - this lens has it! It even comes complete with Microfibre cloth.
The lens is housed in the centre of the scope so offers equal shade from the front hood and rear housing.
