The ZeroTech Thrive X 3-12x44 PHR 3 BDC Turret is a second-focal-plane (SFP) hunting riflescope engineered for short- to mid-range shooting applications. Built on a 30 mm one-piece aircraft-grade aluminium body, it combines a versatile 3–12x magnification range with a 44 mm objective lens. The scope features a dedicated BDC elevation turret and an MOA-based PHR 3 reticle with a floating centre cross, calibrated at 12x magnification for rapid drop compensation in the field. Fully multi-coated lenses with Weathershield protective exterior coating and nitrogen gas purging deliver waterproof, fog-proof, and shockproof performance across standard Australian hunting calibres.

  • Dedicated Elevation BDC Turret: Resettable elevation dial featuring audible 0.25 MOA click values, paired with capped windage adjustments.
  • Side Parallax Adjustment: Smooth side focus mechanism functioning from 10 metres to infinity, supporting both close-quarters rimfire and extended centrefire shooting.

Who is the ZeroTech Thrive X 3-12x44 PHR 3 BDC for?

  • Medium-game deer stalkers — The 607 g unmounted weight provides a balanced, carry-friendly footprint for all-day mobile hunting, while the 3-12x magnification range and 44 mm objective lens deliver reliable clarity and practical target acquisition from dense timber out to typical mid-range engagement distances.
  • Pest and predator eradication shooters — The side parallax focusing down to 10 metres allows this SFP hunting riflescope to eliminate optical parallax error during close-range rimfire or air rifle pest control, while dialling seamlessly up to 12x magnification for longer centrefire shots in open paddocks.

Less suitable for: Long-range target engagements past 600–800 metres, which are better served by a first-focal-plane optic with higher 5-25x or 4-20x magnification and exposed zero-stop turrets; additionally, pitch-black night hunting without spotlights or with forward-mounted night vision clips is better served by an optic featuring an illuminated reticle.
