Tangent Theta 315M

The Tangent Theta 315M Rifle Telescope (3-15x50mm) is a precision sighting instrument initially designed for police and security marksmen, that with its intuitive features it is also a lightweight precision hunting scope with no equal.

Designed as a reduced-weight professional marksman rifle telescope, the Tangent Theta 315M incorporates precise adjustment mechanisms with zero stops and mechanical revolution and windage direction indicators that virtually eliminate adjustment errors. The optical path has been optimized for unsurpassed image quality, allowing the marksman to see minute target detail and to remain in the aim for extended periods without eye fatigue.

50mm objective lens
30mm main tube

eleven reticle illumination settings with rest off positions between each setting
side parallax adjustment from 50m to infinity with advantage of being parallax free after 250m
non-translating knobs with elevation zero-stop
double-turn elevation with revolution and windage direction indicator
3-15x magnification range
lockable rapid adjusting diopter

That Price though?

Put simply this is a scope that has the best turrets and the best optical performance in its class and it weighs under 800 grams, Ideal for the serious hunter. We believe it is the best mountain/backpack hunting rifle scope on the market today. For Australian Sambar hunters travelling to the high country of Victoria that like to shoot beyond 200m this scope has no equal. It is Lighter, faster, stronger and better than its competition. It gets a clear target image faster and you can dial the exact numbers you need the first time without over travel or excessive force. The turrets are in a class of their own. Optically the depth of field and field of view is breath taking and being a first focal plane, simply wind the mag back to 3x and in essence a wonderful duplex perfect for bush stalking is ready for you. Crank it to 10x+ and all the sub-tensions you need for a precision shot are there with unmatched image quality.

With 12 mils of elevation you aren’t carrying extra weight just to dial more, this is a precision hunting scope, 12 mils with most modern cartridges used for Long range hunting will get you to 1200m and beyond so in reality is more than enough. All these features combine to increase your chances and increase your chances of success. Now what does this mean in dollar terms? Well one Sambar hind can yield upwards of 60kg (stags can yield twice this amount or more) Current venison prices (for low end cuts) is $20/kg, so even neglecting the increased values of the more premium cuts, one Sambar is worth upwards of $1200. That’s 4 Deer and this scope has paid for itself, so all that is required is for this scope to capitalise on 4 extra opportunities per year vs an inferior scope and it will pay for itself.
