Engineered for both compound and recurve. At less than 15MM diameter, Halcyon is the smallest diameter carbon stabilizer ever from Easton. Halcyon features 360 Windcutter technology for the steadiest possible hold. The new Halcyon system features the greatest stiffness-to-diameter performance in the 40-year history of Easton carbon stabilization systems. With a wind-beating super-slim 14.7-millimeter diameter, light mass weight, efficient vibration control, and extreme stiffness, Halcyon provides an ideal aiming solution for both compound and recurve competitors. Halcyons slim diameter promotes a superior hold in gusty winds, while the enhanced stiffness means less float during aiming, and more consistent shot-to-shot inertial stability during arrow launch- the most important role of any stabilizer system. Compatible with both 1/4-20 and 5/16-24 weight systems, Halcyon represents the pinnacle of technology for the serious competitor.
