IP67 rated means the scope can be fully submerged in 1 meter of water for 30 minutes without any water ingress. Heavy rain, sudden downpours, or accidental drops into water are absolutely no problem.

The internal chamber is sealed with precision O-rings and filled with dry nitrogen gas. Even when moving between extreme temperature differences — such as stepping from a freezing vehicle into a humid jungle — the lenses remain completely fog-free.

FFP (First Focal Plane): The reticle scales proportionally with magnification. Holdover and ranging marks remain accurate at every power setting — ideal for precision shooting, long-range target work, and PRS competition.

SFP (Second Focal Plane): The reticle stays the same size regardless of magnification. Subtension values are only accurate at one specific power (usually max). The advantage is a bolder reticle at low power — great for hunting and quick target acquisition.

If your primary use is long-range precision, go FFP. If it's hunting or close-to-mid range, SFP works perfectly well.

Zero Stop is a mechanical feature that lets you dial elevation up for long-range shots, then quickly return to your established zero by simply spinning the turret back down — it physically stops at your zero point, so you can never accidentally go past it.

For shooters who frequently engage targets at varying distances, Zero Stop is invaluable. Dial up confidently, take your shot, then return to zero in seconds without recounting clicks or re-verifying.
