ZeroTech Trace 3-18x50 SFP R3 Riflescope: Technical Details and Specifications

Product Overview

The ZeroTech Trace 3-18x50 SFP R3 Riflescope is a precision optical instrument manufactured by ZeroTech Optics, engineered for long-range hunters and precision shooters. This riflescope combines variable magnification, advanced optical design, and practical features for demanding shooting applications.

Magnification and Optical Specifications

The riflescope features a 3-18x variable magnification range, allowing shooters to adapt to different engagement distances and shooting conditions. This adjustable magnification capability makes it suitable for both standard and long-range shooting scenarios. The magnification system is calibrated at the high magnification setting of 18x in the second focal plane design.

The riflescope is equipped with a 50mm objective lens diameter, which provides enhanced light gathering capability essential for clarity across varying lighting conditions. The fully multi-coated lenses ensure consistent optical performance and maximize light transmission throughout the magnification range.

Focal Plane Design and Reticle

The Trace 3-18x50 SFP R3 utilizes a second focal plane (SFP) design, where the reticle calibration is fixed at 18x magnification. This design affects how the reticle scales with magnification changes, making it particularly suitable for shooters who primarily use the scope at its highest magnification setting.

The riflescope is equipped with the R3 reticle, a proprietary ZeroTech reticle system designed for precision targeting and long-range applications. The R3 reticle assists in aiming procedures and provides additional functionality for range estimation and ballistic calculations.
