Amazing Vision
The very best Japanese camera quality lenses which have then been precision ground and honed to give the very best image stability. An extra lens and top quality multi coatings have been added to all the Japanese top grade lenses to enhance light transmission and to reduce any reflections to near none that may cause the rifle scopes to be dull in low light conditions

Superb Optics and clarity of vision
The Diamond Sportsman utilises the very best Japanese Camera quality lenses that have been precision ground and honed for image stability.

Magnify your target 50 times - great clarity even at higher magnigications which is a problem on some lower priced very high magnification scopes.

But with the Diamond Sportman 10-50x60 Multi-coatings have been added to all the lenses to enhance light transition and reduce reflections that cause scopes to become dull in low light conditions.

With these features combined, the result is the highest possible clarity.

Mil Dot Reticle

Classic mil dot range finder reticle

Benefits of Glass Etched Reticles

Glass-etched reticles are way superior to wire for several reasons, most notably is how much finer and cleaner they are when viewed through the scope.

A glass etched reticle, also cannot be broken. Anyone who has shot enough has seen a wire reticle actually break within the reticle field. As the reticle design is etched into the reticle lens, it is static and cannot physically be broken.

60mm Fully Multi Emerald Coated Lens:

  • A big lens which, combined with a 30mm tube gives you superb light capture and transmission resulting in a truly incredible view.
  • The x-large size also gives you very very fast target acquisition and moving target tracking.
  • Especially good in lower light.
  • Fully multi coated with emerald to protect and limit glare and reflections.

10-50x variable magnification

  • Adjust anywhere from 10-50x
  • A true medium to extreme long range FT and hunters scope with a huge range of variable magnification settings.
  • Very Easy and very fast dial adjustment.
  • Exceptional clarity through premium A grade camera quality lens.

You'll get crystal clear focus on 10x at 10 yards.

Lock and reset Windage and Elevation Turrets:

Green anodised, capped all weather target turrets with return to zero ability

Underneath are hand-dialable drums graduated in 1/8” @ 100 yard clicks. These are divided into nine with each section further sub-divided in eight, giving 9” per turn with a shade under six full turns available (50” +) top to bottom.

Updated critical elevation adjustment which has been increased by 25% allowing competitors faster shots without adjustment to the point of impact via the target turrets.

Parallax Explained

At longer distances targets will often "seem" to drift or wobble against their background making locking on them very difficult. This effect is known as parallax. If accurate shots at distance are important to you - small prey head shots, target shooting comps etc then being able to get rid of this problem is critical to your success.

Scopes such as this have Parallax adjustment which basically means you are able to adjust the scope using SWAT (Side Wheel Adjust Turret) to factor it out of the equation and give you rock solid target lock at any distance.

Large wheel Sidewheel included - For finer px adjustment

It is optional to use this so just take it off when not needed - Here without sidewheel
