FOCUS-3 SCOPE

FOCUS-3 scope. A compound bow scope built around an independent lens design, a 30 mm clear aperture and 17 grams of body weight.

Material and specifications

The main barrel is constructed from PPA-CF engineering material. The internal clear aperture diameter is 30 mm. It weighs only 17 grams (excluding front and rear lens hoods and fiber optic rings).

Optics

The custom-manufactured 14-layer coated low-distortion lenses deliver excellent performance in anti-glare, anti-distortion, hydrophobic, and scratch-resistant properties. The independent lens design abandons the traditional “magnifying glass” concept, truly meeting the requirements of compound bow aiming systems.

Featuring a floating lens shock-absorbing structure installed with tension via a silicone ring, this design avoids damage to the lens caused by traditional hard connections while significantly reducing accidental risks from vibrations. It also makes lens replacement or cleaning during equipment maintenance more convenient.

The front sunshade features a serrated anti-reflective structure designed to eliminate glare, while the inner surface of the main scope body is matte-finished. Together they create an inner cavity with high light absorption efficiency.

Aiming points

Optical fiber brightness adjustment ring — the brightness of the optical fiber aiming points is adjusted by controlling the light obstruction amount through a sliding ring, so you get consistent optical fiber brightness both indoors and outdoors.

Fiber optic or sticker pins — the kit includes sticker-type aiming pins and installation aids, enabling quick switching between fiber optic aiming pins and sticker-type pins.

High-brightness level bubble — featuring high-reflective back coating technology, it significantly enhances the visibility of the level bubble, ensuring consistent brightness performance both indoors and outdoors.

Adjustment and compatibility

Replaceable synchronizing ring design — a threaded mounting synchronizing ring design with three sizes of synchronizing ring accessories (large, medium, and small). This precisely adapts to the visual inner diameter of the peep sight in indoor and outdoor environments and during drastic changes in light intensity, eliminating the hassle of frequently switching peep sight inserts.

Synchronization ring calibration — paired with the anti-light-reflective inner cavity and the external yellow synchronization ring, comparing the concentric positions of the black ring and yellow ring creates a reference condition for three-axis adjustment of the sight head.

Independent pitch angle adjustment module — provides independent pitch angle adjustment for Shibuya sights, achieving three-axis adjustment more directly.

Front lens hood

Modular quick-release front lens hood system — simplifies quick lens removal/installation or fiber optic aiming point switching; it can be completed with just one twist and pull.
