GOLF MODE
The Astra Optix PRO A-1 Golf Mode provides the Slope value (also known as the Play Distance) and features Pin Lock which helps you accurately range the golf flagstick.

Golf Mode and Slope (Play Distance): In the golf mode, your rangefinder will first display the Line of Sight (LOS) distance which is 150 yards to the flag in the example below. However, because the flagstick is at an incline, the ball will land short of the flagstick. You will need to adjust your swing or use a different club based on your experience of hitting on an incline (or decline if the flagstick is below you). In the golf mode, the rangefinder will also automatically adjust for the incline (or decline) angle to the flagstick and will display the adjusted “Play Distance” of 190 yards at the very bottom of your display. Select your club based on a yardage of 190 yards. The yardage of 190 yards in this example is the adjusted distance based on the angle of incline.

How to Use – Installing the Battery

Your Astra Optix™ Laser Rangefinder comes with one CR-2 (3-volt) lithium battery preinstalled.
REMEMBER: Remove the battery cap and take out the plastic spacer from the top of the battery before using. The spacer prevents the battery from activating during shipment. Your battery life will depend on the mode you are using and the outside temperature. Your battery should last approximately 10,000 measure­ment readings. Colder environments will cause the battery life to be shorter. Your rangefinder will automatically shut off after 10 seconds of nonuse.

LOW BATTERY: A battery icon ( ) will display when you are nearing the end of your battery life. At this time we suggest changing the battery.

• To change the battery, place a flat-head screwdriver or coin in the battery cover slot. Unscrew the battery cover in the counter­clockwise direction. Remove the cap and dispose of the used battery. When disposing of the battery, follow your local area regulations.
• Place the battery in the compartment so the battery’s positive side is facing up. There is also a positive symbol etched into the underside of the battery cover indicating the positive side should be facing up towards the battery cover.
• Replace the battery cover back on the battery housing by screwing on clockwise to tighten.

REMEMBER: Ensure the battery cover is secured in place in order to preserve the waterproof capability. Do not overtighten the battery cover.

How to Use – Rangefinder Focusing
When just starting to use your rangefinder, you will need to focus the aiming reticle and image that you see in your field of view. Anytime your image and reticle are not in focus, follow the below instructions for focusing your rangefinder.

TIP: If you are an eyeglasses wearer, you can wear your eyeglasses while using the rangefinder. You can also use the rangefinder without your eyeglasses.

• To focus your range finder, first turn on your rangefinder by pressing the Power (Range) Button so that you can see the cross aiming reticle in your field of view. You can focus the aiming reticle and the optical image both at the same time.
• Turn the Eyepiece Diopter Focus either left (counterclockwise or right (clockwise) until the image in your field of view and the Cross Aiming Reticle are clear and in focus with each other. It is best to turn the focus ring until you reach a balance so the reticle is focused and your target in your field of view is focused.
• Your rangefinder optical system is a fixed focus system and is focused from 6 yards to infinity.

TIP: When using the rangefinder as a monocular only (without the rangefinder turned on), you can still further focus your optical image more fine by turning the Eyepiece Dioper Focus as described above.
TIP: When using the rangefinder aiming reticle (when the display is turned on), you will need to focus the reticle by turning the Eyepiece Diopter Foucs as described above. Depending on your eyes and the viewing conditions, you will need to focus the aiming reticle and optical image so that both are in focus.

How to Use – Soft Pouch

Your Astra Optix™ Laser Rangefinder comes with a premium microfiber storage pouch with drawstring closure which doubles as a microfiber lens cloth to help both protect your rangefinder and to provide a convenient way to clean your lenses.

Tips for Using Your Rangefinder

• Your laser rangefinder comes defaulted to the Golf Mode. This rangefinder provides the Slope “Play” Distance when in the Golf Mode. In this mode, it will display the Line of Sight (LOS) Value on the top line and the Slope “Play” Distance on the bottom line. Your rangefinder will calculate the adjusted play distance based on the angle of decline or incline to the flag. This feature is based on hitting a golf ball, and should not be used for hunting.
• In Golf Mode, to make it easier to range the flagstick, your rangefinder has Pin Lock technology. When you press the Power (Range) Button down to range the flag, the rangefinder will display the nearest distance value (Golf Flagstick) of a group of targets that are within your field of view. The cross indicator ( ) will flash giving you visual confirmation that you have locked on to the golf flagstick. For optimum results, hold the rangefinder as still as possible on your target for up to 2 seconds or until you see the distance appear on your display.
• For hunting, choose the Hunt Mode. The rangefinder will display the Line of Sight (LOS) distance, Horizontal (Angle Corrected) distance, and the Angle value. For archery or shooting, you can use the horizontal angle-corrected shoot-at distance. The horizontal angle corrected distance is only for hunting. For hitting a golf ball, use the golf mode which provides the slope “play” distance.
• Under ideal conditions, your Astra Optix™ Pro A-1 Laser Rangefinder can measure the distance of reflective objects out to 800 yds. It can also measure a tree out to 500 yds., a deer out to 250 yds., and the flag out to 250 yards. The Pin Lock feature works up to a distance of 250 yards. The type of target you are ranging strongly impacts the maximum ranging distance.
• Shiny reflective objects such as metal buildings will range much better than less-reflective objects such as trees, animal fur, bushes or grass. Objects that are more dense, such as trees or rock, will range better than bushes or grass. Bright-colored objects normally range better than dark-colored objects. Rain, fog, snow, bright sunny days and dusty days will reduce the overall ranging performance. Cloudy days without fog, snow, rain or dust blowing in the air provide the best ranging conditions. Targets that have a flat surface 90° to the laser emitting from the laser rangefinder range better than targets that have a curved surface, or are positioned at an angle in relation to the emitted lase
• The Low Battery symbol will flash when the battery life is lower than 25%. We recommend that you change the battery as soon as possible. If at any time, your rangefinder freezes or is not responsive after turning it on, reset the rangefinder by removing the battery. Wait 10 seconds and then replace the battery. This will usually fix the issue.

Specifications and Features

Troubleshooting

• If at any time, your rangefinder freezes or is not responsive after turning it on, reset the rangefinder by removing the battery. Wait 10 seconds and then replace the battery. This will usually fix the issue.
• If you are trying to range a target and you are seeing dashes (- – – -) in the display, it is possible that you are either too close (less than 6 yards) or too far away from your target. In addition, your laser rangefinder’s laser maybe missing the target and aimed towards an open sky which will also show a non- reading (—-).
• If you can not see a full image (all of the field of view) when looking though your laser rangefinder, your eyes may be positioned either too far away or too close to the eyepiece. Move your head back a little from the eyepiece or move towards the eye-piece a little until you can see the full circular field of view. Your rangefinder can operate between temperatures of 14° F and 120° F. If temperaturesare lower than 14° F, and if your rangefinder is not responding, just bring the product to a warmer location. After the rangefinder warms back up and is within the normal operational temperatures, it will be operable again.
