Barnett 4x36mm Crossbow Scope

Introduction

This scope is designed, engineered, and built to offer years of trouble-free service. When used properly, it will deliver outstanding performance in the field, while increasing your level of shooting satisfaction. To avoid damaging the scope or injuring yourself during its operation or use, you must carefully read these instructions completely, and heed all warnings.

A WARNING

• NEVER attempt to look at or view the sun using a scope. Permanent eye damage will result.
• Make certain the crossbow is unloaded and uncocked when attempting to make adjustments to this scope, including installation/removal, sighting-in, and any other manipulation.
• NEVER shoot a crossbow anywhere other than an approved shooting range. Strictly follow the warning and precautionary statements included with your crossbow instruction manual.
• Make certain the scope is mounted far enough forward to preclude contacting it when shooting. Rearward movement (i.e., "crossbow recoil") occurs when the crossbow arrow is discharged. Placing your eye or eyes in close proximity or against the scope while shooting will result in personal injury.
• Do not attempt to disassemble or clean the scope internally. Attempting to disassemble the crossbow scope immediately voids the warranty and will render the scope unusable.
• Keep the protective lens covers in place when the scope is not in use.
• As required, wipe the external optical surfaces with the provided lens cloth or an optical quality lens paper. Remove any external dirt or sand with gentle air pressure (i.e., canned compressed air) and a soft brush to avoid scratching the lens finish.
• When used in a salty environment, wipe the scope with a damp cloth, then with a dry cloth. Wipe down the metal portions of the scope with a silicone cloth to protect against corrosion. Do not spray with a silicone lubricant aerosol.
• Store this scope in a moisture-free environment. AVOID STORING the scope in passenger compartments or trunks of vehicles as temperature can adversely affect the scope's internal lubricants and sealants.
• Failure to follow these instructions may result in serious injury and/or property damage.

Adjusting the Ocular Lens

The ocular lens housing has a fast-focus thread, which quickly adjusts to make the reticle as sharp as possible for your individual eyesight. Set the focus of the reticle in similar light conditions and at the approximate range (distance) at which you expect to use your scope. Try not to stare at the reticle to get it in focus; it should be sharp the moment you glance through the scope. Note: It may take several attempts to "dial-in" the perfect focus.

Adjusting Eye Relief/Field of View

A good, clear, level crossbow scope "sight picture" or "field of view" is achieved when the crossbow is held in your normal shooting position and a full field can be viewed without straining or stretching your head and/or neck. This optimum adjustment may require moving the scope assembly either forward or backward on the crossbow's picatinny rail. Perform the following steps to adjust:

1. Support the uncocked/unloaded crossbow on a sturdy surface and loosen the scope ring base cap screws using the provided 7/64" Allen wrench.
2. Raise the crossbow to a standard shooting position and look through the scope. Adjust the scope forward or backwards as necessary until a clear, unobstructed field of view can be seen without straining your head and/or neck. Note: Make certain your eye is not in close proximity to the scope assembly. Positioning your eye too closely to the scope assembly will result in injury upon the crossbow's recoil. If your eye is too close to the scope, use the ocular lens adjustment to adjust the scope focus and move your eye further from the lens to preclude contacting it when shooting.
3. Rotate the scope so the horizontal crosshair is parallel to the string and limbs. Once parallel, retighten the top ring screws and double check that the scope hasn't moved from its optimal functioning position.
4. Once set, check the scope assembly every few shots for tightness and ensure it stays securely mounted. Readjust/retighten as appropriate.

Initially Zeroing the Scope

Once you've read your crossbow instruction manual in its entirety and located a safe and secure place to shoot, double-check your backstop. Backstops are used to stop errant shots and protect surrounding property and/or persons from damage and danger.

1. Place the target (one approved for "crossbow use") on the backstop at a measured distance of 10 yards (30 ft. 9.14m).
2. After following all of the precautionary statements and heeding all warnings contained herein and thereto, aim the top (20 yard aim point) reticle at the center of the target and execute a shot. Note the point of arrow impact on the target.
3. Remove the caps from the windage and elevation turrets and make a suitable adjustment to the turret to bring the point of impact (POI) closer to the point of aim (POA).

POINT of AIM (POA) VS POINT of IMPACT (POI)

Two terms are used exclusively in the optics industry; those of "point of aim" and "point of impact". Point of aim or POA, simply describes the spot on the target where the shooter is aiming. Point of impact simply refers to where your arrow actually strikes the target. Once you have established your POA (where you intend to hit) and your POI (where you actually hit) perform the following steps to sight in your scope:

1. Establish in what direction(s) the bullseye was missed. For instance, if the shot was high, rotate the elevation turret clockwise.
2. Note: At 10 yards, both the windage (left and right) turrets move the POA 1/20th of an inch per "click." So 20 clicks will move the POI approximately one inch.
3. After achieving the bullseye at 10 yards, move back to 20 yards (60 feet; 18.2 m). Repeat the previous steps to zero-in the scope at 20 yards.
4. Note: At 20 yards, both the windage (left and right) turrets move the POA 1/10th of an inch per "click: So 10 clicks will move the POI approximately one inch.

Arrow Speeds & Reticle Aim Points

Your crossbow scope is equipped with defined reticle aiming points; each of which represents a distance, traditionally in yards, to your target. Every crossbow shoots arrows at varying speeds downrange. Therefore, each of these aiming points will represent a different target distance according to the speed of the individual bow.

Faster crossbows (those exceeding 400 feet per second) send arrows downrange at very flat trajectories, resulting in very tight arrow groups, out to typically 40 yards. In this case, these reticle aiming points may represent 20, 30, 40, 50, 60 and 70 yards, respectively from the top reticle aiming point down to the bottom aiming point.

Note: You will notice the scope's aiming points are not spaced evenly; this is because as the target distance increases, arrow drop becomes more pronounced. For crossbows with arrow speeds ranging from 350 to 399 feet per second, for instance, the aiming points may represent target distances of 20, 35, 45, 60 and so on. It is VERY IMPORTANT that you understand each aiming point will represent a different target distance as determined by your individual bow's arrow speeds. As such, it is incumbent upon you to spend considerable time at the range, determining exactly which target distance correlates with each individual reticle aiming point.

Shooting Aiming Point Gaps

In many instances, you may encounter targets at distances which fall between two aiming points; say for instance, 38 yards. In these cases, you may consider shooting the gap between your 30 and 40 yard aiming points (depending on your bow's speed of course). This is referred to as "shooting the aiming point gap". It is highly recommended to carry a laser range finder with you in all hunting and shooting excursions. This practice minimized guessing yardage distances to targets and leads to considerably more success in the field.

Illuminated Reticle

The 4 x 36 mm crossbow scope is equipped with six reticle aim points, which can be illuminated either red or green. The illumination on/off switch and illumination intensity control rheostat for operating the illumination is positioned on the scope's side (illumination dial). The system is powered by a CR2032 3 3V coin-style battery, which is located under the screw-on battery cover. When replacing the battery, ensure that the "positive" (+) is facing up. The reticle illuminates in 2 daytime and nighttime friendly colors: 1) red and 2) green. There are 5 light-level intensities for each color. These range from low intensity for low-light use and high intensity for use in bright conditions. To power on the illumination, simply rotate the turn dial either clockwise or counter-clockwise. Depending on the direction, the reticles will illuminate either red or green. Continue rotating the dial to increase illumination intensity. To turn off the illumination, rotate the turn dial back to either "B" position as indicated at the base of the dial.
