The R3 reticle allows the shooter to enjoy all aspects of a second focal plane (SFP) scope without losing the ability to ‘hold over’ with extreme precision for long range shots.

The R3 features a floating center dot and subtensions of 1 MOA marked by dots with a hash mark every 4 MOA. Heavy bars at 3, 6, 9 and 12 o’clock make target acquisition a breeze.

    Recently I upgraded a scope to the Zerotech Trace 4.5-27×50 for Range/Target use.
    I’d done a fair swag of research on various brands, magnifications, reticle options etc & after some deliberation I chose the Zerotech Trace.
    I’m more than happy with the Zerotech brand & the clarity, light transmission & “crispness” of the sight picture image.
    This scope represents great value for money, great product & of course an Aussie owned business figured in my choice.
    I’d buy another Zerotech Trace without a second thought.
