3. Pemasangan dan Pemasangan
Proper mounting is crucial for accuracy and consistent performance. It is recommended to have your scope mounted by a qualified gunsmith. Ensure the scope rings and base are compatible with your rifle and the scope's 30mm main tube.
- Selamatkan Pangkalan: Attach the scope base securely to your rifle's receiver according to the manufacturer's instructions.
- Pasangkan Cincin: Place the bottom halves of the scope rings onto the base.
- Position Scope: Carefully place the Predator 4 riflescope into the bottom rings. Adjust the scope's position forward or backward to achieve proper eye relief.
- Tahap Reticle: Rotate the scope until the E3 reticle is perfectly level with the rifle. Use a reticle leveling tool for best results.
- Install Top Rings: Place the top halves of the rings over the scope and tighten the screws evenly, following the torque specifications provided by the ring manufacturer. Do not overtighten.
- Semakan Akhir: Verify that the scope is securely mounted, the reticle is level, and eye relief is comfortable.
4. Initial Adjustments and Zeroing
4.1. Pelarasan Diopter
This adjustment focuses the reticle for your individual eyesight, ensuring the reticle appears sharp and clear.
- Halakan skop pada latar belakang yang jelas dan terang (cth, langit cerah atau dinding kosong).
- Lihat melalui skop dan cepat pandang jauh.
- While looking away, adjust the diopter ring on the eyepiece until the reticle appears perfectly sharp the instant you look through the scope.
- Repeat until the reticle is instantly clear without eye strain.
4.2. Sifar Skop
Zeroing aligns the scope's point of aim with the rifle's point of impact at a specific distance (e.g., 100 yards).
- Set up a target at your desired zeroing distance (e.g., 100 yards).
- From a stable shooting position, fire a group of three shots.
- Perhatikan titik impak berbanding dengan titik sasaran anda.
- Adjust the elevation and windage turrets. Each click of the turret moves the point of impact by 1/4 MOA (Minute of Angle). Turn the turrets in the direction indicated to move the point of impact towards the center of the target.
- Fire another group of shots and repeat adjustments until the rifle is zeroed.
4.3. Pelarasan Paralaks
The parallax adjustment knob (located on the left side, integrated with illumination control) eliminates parallax error, ensuring the reticle and target are on the same focal plane. This is especially important at higher magnifications and varying distances.
- While looking through the scope, turn the parallax knob until the target appears sharp and clear.
- To check for parallax, slightly move your head up and down or side to side. If the reticle appears to move relative to the target, parallax is present. Continue adjusting until the reticle remains stationary on the target regardless of slight head movement.
- The parallax adjustment ranges from 18 yards to infinity.
5. Mengendalikan Skop
5.1. Pelarasan Pembesaran
The magnification ring is located at the front of the eyepiece. Rotate it to select your desired magnification level between 4x and 16x. The E3 reticle is in the second focal plane, meaning its size remains constant regardless of magnification, allowing crosshairs to remain fully visible.
5.2. E3 Reticle Usage
The illuminated E3 reticle is designed for quick and accurate target acquisition and holdovers. It features:
- BDC (Bullet Drop Compensation) Holdover Marks: These marks are provided for each 100-yard increment along the lower vertical crosshair, assisting with bullet drop at various distances.
- Windage Reference Marks: The reticle includes 5 MPH and 10 MPH crosswind reference marks for every 100-yard increment, aiding in wind compensation.

5.3. Pencahayaan Reticle
The illumination control is integrated with the parallax adjustment knob on the left side of the scope. It features 11 total brightness levels (5 day / 6 night settings).
- Rotate the knob to increase or decrease the reticle brightness.
- Intermediate "off" positions are present between each brightness level, allowing you to quickly return to your preferred setting.
- The illumination is powered by a CR2032 battery.
6. Penjagaan dan Penyelenggaraan
Proper care will ensure the longevity and performance of your Steiner Predator 4 riflescope.
- Kanta Pembersihan: Use a soft lens brush to remove dust and loose particles. For smudges or fingerprints, use a clean microfiber lens cloth and a small amount of lens cleaning solution. Breathe lightly on the lens to fog it, then gently wipe with the cloth. Avoid harsh chemicals or abrasive materials.
- Pembersihan Badan: Lap badan skop dengan lembut, damp kain untuk membuang kotoran dan serpihan. Keringkan dengan teliti.
- Storan: Store the scope in a cool, dry place, preferably in its original packaging or a protective case, away from direct sunlight and extreme temperatures.
- Penggantian Bateri: Replace the CR2032 battery for the reticle illumination as needed. Ensure correct polarity.
- Kalis Air dan Kalis Kabus: The scope is nitrogen-filled and sealed for waterproof and fogproof performance. Do not attempt to disassemble the scope, as this will compromise its integrity and void the warranty.
