Shibuya Technology

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.
