Shibuya Technology

Polygonal Extension [patent pending]

After repeated research and testing to redefine vibration, we have developed a completely new concept carbon extension. By pursuing vibration damping not only in the material but also in the shape, we have achieved vibration damping of 80% or more of the initial vibration in the theoretical value.

New Extension Fixing System

A completely new design fixing system that pursues reliable locking and reproducibility.
By increasing the maximum diameter of the knob itself, it is possible to securely fix it with a smaller force than before. It is a new fixing system that has a large ground contact area that holds down the extension, and is simple and will not loosen even when shooting for a long time.

Sight Tape Plate

Cutouts are provided on both sides for attaching plates for sight tape.
Equally spaced graduated plates and blank plates for sight charts are standard equipment and can be attached to both the left and right sides according to the player's taste and competition style.

New Sight Pin Stopper

Uses a sight pin stopper that can be released without using a tool.
The adjustment time is greatly reduced by overwhelming improvement in operability. We provide a generous shooting.

Double Mount + Short and Small Elevation Type lineup added

A two-stage mount + short and small elevation set has been added to the lineup.
The double mount design has succeeded in reducing the weight of the tip by shortening the overall length of elevation without impairing the vertical adjustment range of the site. The weight reduction of the tip gives an overwhelming advantage over vibration. This top light style is the site that focuses on vibration damping most in the history of our products.

ULTIMA RCⅡ

The most popular competition recurve site in the world.

A standard model of SHIBUYA's recurve bow site for competitions, which has many achievements.

Total weight reduction and fine-tuning of weight balance

Site weight is an important factor for archery players when buying a new site. The weight of the Ultima RCⅡ site has been reduced to 201g, but mainly by reducing the weight of the elevation bar and site block area, it feels lighter than the actual weight when attached to the bow. prize. Furthermore, the vibration is dramatically reduced by making it lighter (on the elevation bar side).

Improved Site Pin Locking Mechanism

The Altima RC site's sight pin locking mechanism was simple and reliable, allowing you to easily lock the sight pin with a single screw. The Altima II RC site has been further improved, and a new mechanism that uses a conical washer eliminates the risk of contact between the sight pin screw and the lock screw and causing damage.

Press-fit insert elevation drive shaft shock absorber system

Instead of supporting the elevation drive shaft of the Altima RC site, a newly developed shock absorber system has been adopted to improve the effect of suppressing vibration and sound during launch. As a result, the Ultima II RC site has become the quietest and most reproducible site in Shibuya Archery history.

X-LOCK System [Patent No. 4050731]

X-LOCK system that allows readjustment of the tightness of the elevation bar and site block. The precision resin spacer, which can be said to be the heart of X-LOCK, also uses parts developed exclusively for it.
In addition, by newly incorporating a sheet metal guard with a leaf spring function, the degree of adhesion between the site block and the elevation bar is improved, achieving high reliability.

Newly developed gripper processing adjustment knob

The Altima II RC site has a completely new non-slip pattern with a high grip on the adjustment knob and mount knob. It provides a comfortable up / down / left / right adjustment operation feeling and enables reliable fixing and adjustment to the site mount.

Easy and reliable fine adjustment

One of the most requested requests from players was that they wanted a scale for the left and right adjustment parts. At the Altima II RC site, the left and right adjustment parts are laser-engraved, making fine adjustments easy and accurate, making it possible to improve reproducibility.

ULTIMA OKULUS SCOPE

The finest compound scope in pursuit of balance that fits under all conditions.
Equipped with a new mechanism that responds to the changing center of gravity by using a wide variety of accessories such as sunshades and decal rings.

Abundant Accessories

A lineup of genuine accessories such as sunshades, back sunshades, decal rings, and fiber kits. A wide range of settings that can be adapted to all players and environments is possible.

Gravity Shift

Equipped with a new center of the gravity adjustment mechanism. The change in the center of gravity caused by the installation of accessories can be adjusted. It reduces the occurrence of defective vibration and tilting of the scope body. The scope rod can be set to the proper position in any combination.

Non-glare Mechanism

In addition to the conventional anti-reflection groove processing, the entire housing is matted to minimize internal reflection. Ensures an optimal field of view in all environments.

Sight Light Compatible

Supports the installation of site lights, which are popular in 3D competitions. (Please use another company's product for the sight light.) Since the light is designed to hit the center of the lens, reliable lighting is possible.

Fiber Kit 3 sizes available

We have a run-up of 3 sizes, 0.10, 0.19, and 0.29, which are popular in target competitions. The fiber tube is fixed by a mechanism that can be easily attached and detached.
