 Q&A

Q: Who is this designed for?
A: Precision shooters, long-range hunters, and competitive marksmen who want an integrated rangefinder and ballistic solution directly on their rifle.

Q: Does it replace a handheld rangefinder?
A: Yes, in most cases. It allows you to stay on the rifle and continuously range targets without breaking shooting position.

Q: How accurate is the ballistic solver?
A: Extremely accurate — it uses Applied Ballistics Elite with custom profiles for various calibers, bullet weights, and environmental conditions.

Q: Can it be used at night?
A: The OLED display works in low light, but it is not a night-vision device. Pairing with thermal or night optics may still be possible depending on setup.

Q: Is it compatible with all rifles?
A: Yes, as long as your rifle has a Picatinny rail for mounting. Works with both bolt-action and semi-auto platforms.

 Maintenance Tips

• Keep the lens surfaces clean with lens-safe cloths and covers.

• Regularly check and tighten mounting screws after heavy recoil sessions.

• Recharge battery fully before long shooting sessions.

• Store in a dry, padded case to protect electronics and optics.

• Update ballistic profiles via Bluetooth app for the most accurate data.
