March 48x52 High Master

• 48x fixed magnification: A dedicated high-power image keeps the sight picture consistent from shot to shot, which is especially useful for benchrest and F-class style target work where repeatable aiming matters more than zoom flexibility.
• High Master optical system: Super ED and high-refractive-index lens elements help reduce chromatic aberration and shimmer effects, giving a cleaner view of bullet holes, target edges and mirage in demanding light and heat conditions.
• Side focus from 10 m to infinity: Broad parallax adjustment lets the scope stay precise across short-range benchrest, rimfire and air-rifle distances as well as longer target setups, with sharper target definition and reduced aiming error.
• Capped target turrets with multi-turn elevation: The turret layout provides generous adjustment travel for careful zeroing and load development while keeping the controls protected against accidental movement during transport and handling.
• 30 mm argon-filled body: The waterproof, fogproof and shockproof construction is built for regular competition use, helping the scope remain reliable through changing weather, temperature shifts and repeated recoil.

About the March Fixed Power Series

The March Fixed Power series was introduced in 2017 as a specialist line for shooters who want the consistency of a dedicated high-magnification target scope rather than a general-purpose variable. In the current family, March offers the 48x52 High Master alongside the 40-60x52 EP-Zoom, both built around a 30 mm tube, second-focal-plane layout and High Master optics. The series is aimed squarely at short-range centerfire benchrest, rimfire benchrest and air-rifle benchrest, where a stable aiming image and precise optical definition are more important than broad magnification range.

A key characteristic of the line is its use of the High Master lens system with two Super ED lens elements. This optical design is intended to suppress chromatic aberration and maintain a sharper, higher-contrast image, which matters when reading mirage, separating scoring rings and holding on very fine target detail. Within the family, the fixed 48x model prioritizes absolute simplicity and repeatability, while the EP-Zoom version adds externally adjusted magnification without point-of-aim shift. That makes the series a focused choice for competition shooters who value optical precision, disciplined mechanical design and a format tailored to formal target shooting.

About the March 48x52 High Master

The March 48x52 High Master is a fixed-power riflescope built for shooters who want a dedicated aiming system for precision target disciplines. Its 48x magnification and 52 mm objective lens are geared toward careful shot placement on small targets, making the scope particularly well suited to benchrest, load testing and other applications where the rifle is fired from a stable position and the target must be read in fine detail. Because the magnification never changes, the sight picture remains familiar and repeatable, which helps experienced shooters maintain a consistent hold and visual reference through long strings of fire.

The optical system is what sets this model apart. High Master optics use Super ED and high-refractive-index lens elements to reduce color fringing and improve contrast, which is valuable when trying to resolve bullet holes, target borders and mirage. March also notes improved shimmer protection in this design, a practical advantage on hot ranges where heat waves can make aiming difficult. The second-focal-plane reticle stays visually fine at this fixed magnification, keeping more of the target visible for precise aiming rather than covering it with heavy reticle structure.

Mechanically, the scope is configured for deliberate target use. Capped target turrets offer multi-turn adjustment with 10 MOA per turn, while side focus from 10 m to infinity allows accurate parallax correction across a wide range of target distances. A 30 mm tube, argon filling and waterproof, fogproof, shockproof construction round out a design that is meant to stay dependable on the firing line without unnecessary complexity.

About March

March is the riflescope brand of DEON Optical Design Corporation, a Japanese company established in 2004 and headquartered in Chino, Nagano Prefecture, Japan. DEON designs and manufactures March custom rifle scopes, with the scopes assembled in Japan from Japanese-made components. The company focuses on specialized target and precision-shooting optics rather than broad mass-market lines, and its range includes March-FX, March-X, Genesis and High Master models.

March has built its reputation around compact mechanical design, very high magnification capability and advanced lens systems for demanding shooting disciplines. The company introduced its first 40x52 mm benchrest scope in 2007 and added Super ED lenses in 2017, a development that is directly relevant to High Master models such as this one. In March optics, the emphasis is typically on precise tracking, specialized competition formats and optical designs intended to control aberrations and maintain image quality at magnifications where small optical flaws become easy to see.
