Six red brightness settings, a 6x zoom range and adjustable BDC references in a 22.3-ounce backcountry hunting scope.
ZeroTech Optics USA introduces the Thrive HD 2.5-15x50 – PHR 2 Illuminated, combining a lightweight hunting configuration with illuminated aiming references and an Adjustable BDC Turret. The 22.3-ounce riflescope brings six red brightness settings to a 2.5-15x optical system, giving backcountry hunters an illuminated option in the Thrive HD family without moving away from its five-marker elevation system.
Six brightness levels give hunters control over the illuminated aiming element as light conditions change. Lower settings suit dimmer surroundings, while higher settings suit brighter ones, allowing the aiming reference to be adjusted to the scene rather than relying on a single intensity. The second focal plane reticle maintains its apparent size through the zoom range, and its MOA hold references are calibrated at 15x.
The Adjustable BDC Turret keeps the hunter's confirmed elevation references on the scope. Its five markers are positioned from range-verified data and lock independently, while the full 0.25 MOA scale remains visible underneath. That preserves conventional adjustment alongside the personalized markers. The system is built around the data established for the rifle and load, rather than a single factory-set trajectory.
The 2.5x low end provides a 40.4-foot field of view at 100 yards, suited to closer cover and timber. At 15x, the field of view narrows to 6.8 feet at the same distance for a closer look across open terrain. A 50mm objective, fully multi-coated lenses and parallax adjustment from 10 yards to infinity complete an optical configuration designed to handle more than one type of hunt.
A 30mm 6061-T6 aluminum maintube provides the housing for 60 MOA of internal elevation adjustment and 60 MOA of windage, with 0.25 MOA clicks on both axes. Eye relief is 4.0 inches. IPX7 waterproofing and fogproof construction address the wet weather and changing conditions that can accompany a long approach or a full day in the field.
The result is a 22.3-ounce scope that pairs adjustable illumination with a useful low-power field of view and a 15x top end. A standard capped turret is included alongside flip-up covers and a removable magnification throw lever, allowing hunters to choose the turret configuration they prefer. The scope is backed by the ZeroTech Triple-A Lifetime Warranty.
