Zero Tech Optics Thrive HD Features The Zero Tech Optics Thrive HD is built around a First Focal Plane illuminated LR reticle so the reticle subtensions stay accurate for ranging and holdover at any magnification setting from 4x to 16x. This FFP design lets a shooter dial in close fast shots at low power and stretch out to precise long range hits at full magnification without recalculating holds between settings. The 44mm objective lens gathers ample light for a bright clear image while the 30mm main tube provides generous internal travel for windage and elevation adjustment rated at 20 MRAD and 26 MRAD respectively. Parallax adjustment from 10 meters to infinity lets the shooter remove parallax error at both close range and distant targets keeping the reticle locked onto the point of aim. At 23 ounces the Thrive HD stays light enough for all day carry in the field while its 30mm tube and robust housing stand up to recoil and rough handling. An eye relief of 93mm keeps the shooter s eye safely away from the ocular lens under heavy recoiling rifles and the exit pupil ranges from 11mm down to 2.75mm across the zoom range for a bright image in low light at low power. The scope ships with heavy duty alloy flip up covers a dedicated riflescope multi tool for those covers an instruction manual a reticle range chart and a microfiber cleaning cloth. This complete package makes the Zero Tech Optics Thrive HD a ready to mount riflescope for hunters and shooters who want a single versatile optic for both field and range work.
