Finer Adjustment — SHIBUYA’s Smallest Click Increment
Vertical and horizontal adjustments now move approximately 0.04 mm per click, an improvement from the previous model’s 0.05 mm.
This enables ultra-fine tuning to meet the micron-level precision demanded by competitive archers.
Zero Backlash — ZPE System Integration
The ZPE System, highly acclaimed in the CP PRO and CPX III series, is now adopted in the CP PRO G2 as well.
By optimizing the internal structure, true zero backlash has been achieved.
Even during reverse adjustments, each click responds firmly, allowing for more accurate sight calibration.
SIGHT SCALE PLATES
Both sides of ULTIMA CPX’s elevation bar feature recessed metal sight scale plates. Each ULTIMA CPX Ⅳ includes a blank plate and reference scale. 8 double-sided sight scale plates, for a total of 16 scale options, are available sold separately. Printed sight tapes can be used on the blank plate supplied.
FLAT SHELF INDICATOR PIN
TRIA-LOCK SYSTEM
The innovative new Tria-Lock system encloses the scope rod holder from three sides, keeping it perfectly aligned and without play to produce a rattle-free, zero-tolerance environment.
X-Lock System US Pat No. 7,287,335
Re-adjustable, zero-tolerance fit between the windage unit and sight frame. Super-slick and durable polyacetal resin guide spacers enclose the elevation rail, re-adjustable at the turn of a set screw. All parts field-adjustable and -replaceable!

ULTIMA CPX Ⅳ
Product development
Since the release of SHIBUYA’s first compound sight in 2005, the series has evolved through the CPX, CPX2, and CPX3 models.
Incorporating continuous user feedback, SHIBUYA has refined operability, precision, and reliability—culminating in the creation of the ULTIMA CPX IV.
Every adjustment mechanism and structural detail has been re-engineered from the ground up to deliver smoother, more secure operation.
It achieves both the fine-tuning precision demanded by top-level archers and long-term stability that endures years of use.
As the most balanced and versatile model in the CP series, the ULTIMA CPX IV combines exceptional ease of use with outstanding build quality—making it a trusted choice for compound archers of all levels.
