Shibuya Sight Ultima RC PRO Recurve 520-9-A

Recurve sight from Shibuya.

This model (520-9-A) is a classic sight for the recurve archer. There is a large vertical adjustment range of 107 mm, which is especially useful with a draw weight of less than 40 lbs (for comparison: Shibuya Ultima II RC: 97 mm, Arc Système SX200 95 mm, Decut DC-RE 100 mm, Win&Win WS700 109 mm).

This sight is equipped with a type "A" extension bar, which means that it is stiffer than type "B" (see recommended products below). The stiffer model is especially designed for archers with a higher draw weight to better cope with the higher/stronger vibrations. However, the type "A" extension bar is also suitable for archers with a lower draw weight. Type "A" is 12 grams heavier than type "B".

Key features:

• The Ultima RC PRO is the newest member of Shibuya's Ultima family.
• The extension bar is made of carbon and most of the other parts are made of light and strong aluminium.
• Attractive, modern polygonal extension bar design for even better damping and vibration control.
• The vertical threaded rod is suspended in a damped manner to prevent vibrations and noise.
• Sight block is guided over two diagonally mounted surfaces with plastic glides, thus no play between sight carriage and rail.
• Large knob for quick adjustment or removal of the sight block.
• The quick adjustment screw has a larger contact surface to the extension bar and thus ensures that the extension bar is fixed even more securely.
• Fine adjustment of the vertical axis 1/480" (0.05 mm) per click.
• Fine adjustment of the horizontal axis 1/640" (0.04 mm) per click.
• There is a metal scale on both sides of the adjustment rail. One has a standard scale, the other is blank and can be individually labeled.
• The locking screw of the lateral coarse adjustment has been replaced by a thumb screw and can thus be loosened by hand.
