This scope represents an entry-level to mid-range optic with versatile performance characteristics suitable for general hunting applications. ## Magnification and Optical Specifications ### Magnification Range The riflescope features a **3-12x variable magnification range**, allowing shooters to adapt to different engagement distances and hunting scenarios. This range provides: - **Low magnification (3x)**: Wide field of view for closer targets and faster target acquisition - **High magnification (12x)**: Enhanced detail and precision for longer-range shooting ### Objective Lens The riflescope is equipped with a **44mm objective lens diameter**, a specification that directly influences the light-gathering capability and optical performance of the scope. This objective lens size contributes to: - Moderate light transmission and brightness - Balanced optical performance across varying lighting conditions - Practical sizing for hunters in diverse environments ### Field of View At 100 metres, the Thrive 3-12x44mm provides a field of view specification of: - **Low magnification**: 12.9 meters - **High magnification**: 4 meters These measurements indicate the visible area through the scope at 100-meter distance, enabling shooters to assess their viewing capability at different magnification settings. ## Optical Design and Focal Plane Configuration ### Second Focal Plane (SFP) Design The riflescope utilizes a **Second Focal Plane configuration**, where the reticle is positioned in the second focal plane of the optical system. In this design: - The reticle size **remains constant** regardless of magnification adjustments - The reticle subtensions vary with magnification changes - The reticle is calibrated at a specific magnification level for accurate holdover calculations ## Reticle System ### PHR 3 Reticle The scope features the proprietary **PHR 3 reticle**, a ZeroTech-designed optical component created for specific hunting applications. This reticle assists shooters with: - Aiming and targeting procedures - Range estimation at different magnification levels - Precise shot placement in hunting scenarios The reticle manual is provided with the riflescope to explain the PHR 3 reticle specifications and proper usage techniques. ## Mechanical Construction and Adjustments ### Tube Construction The riflescope features a **30mm main tube diameter**, which is standard for mid-range hunting optics. This construction size: - Provides enhanced light transmission compared to smaller 1-inch tubes - Offers greater adjustment range capability - Supports the installation of various mounting systems ### Elevation and Windage Adjustment The scope incorporates **capped turrets with 0.25 MOA (minute of angle) adjustments**, enabling precise vertical and horizontal corrections: - **Elevation adjustment**: Allows vertical correction of bullet impact - **Windage adjustment**: Permits horizontal correction for wind drift - **60 MOA internal adjustment range**: Provides substantial vertical aiming capability for different shooting distances - **Capped design**: Protects the adjustment mechanisms while maintaining full functionality ## Optical Coatings and Light Transmission The riflescope is equipped with **fully multi-coated lenses** that provide: - Consistent optical performance across varying lighting conditions - Enhanced clarity and light transmission - Strong brightness regardless of environmental factors - Superior image quality in low-light shooting scenarios ## Weatherproofing and Durability ### Weathershield Lens Coating The scope features **Weathershield lens coating** for environmental protection, protecting against: - Moisture and humidity - Dust and debris - Environmental degradation - Fogging in varying temperature conditions This protective coating ensures the riflescope maintains optical integrity and functionality in challenging field conditions. ## Exit Pupil Specifications The Thrive 3-12x44mm riflescope has the following exit pupil diameter characteristics: - **Low magnification**: 14.4mm - **High magnification**: 3.7mm These measurements indicate the diameter of the light beam exiting the scope's eyepiece, affecting brightness and eye relief comfort at different magnification levels. ## Eye Relief The riflescope provides **eye relief ranging from 85-91mm**, offering comfortable viewing distance between the shooter's eye and the ocular lens. This specification ensures safe operation and comfortable extended shooting sessions. ## Weight and Dimensions The Thrive riflescope weighs approximately **540-607 grams**, making it a relatively lightweight option suitable for hunters who prioritize portability without sacrificing optical quality. ## Included Accessories and Documentation ### Box Contents When purchasing the 3-12x44mm Thrive PHR 3 Riflescope, the package includes: - **Instruction Manual**: Comprehensive operational and technical guidance - **Product Manual**: Detailed specifications and maintenance information - **Reticle Range Chart**: Distance-based hold points and range estimation reference - **High-Quality Microfibre Cloth**: For cleaning and maintaining the lens surfaces ## Application and Target Market The ZeroTech Thrive 3-12x44mm PHR 3 Riflescope is designed for: - **Entry-level to mid-range hunters**: Seeking dependable accuracy at a practical price point - **General hunting applications**: Suitable for moderate to extended-range hunting scenarios - **Varied hunting conditions**: Effective across diverse environmental and weather conditions ## Manufacturing and Support The riflescope is manufactured by **ZeroTech Optics**, an Australian precision optics company founded in 2018 with over 50 years of combined expertise in the optics industry.
