Tips for Using Your Rangefinder
◆Your laser rangefinder comes defaulted to the Slope-Off Mode. In this mode, it
will display the Line of Sight (LOS) Value.
◆This rangefinder also features Slope Mode.In Slope Mode your rangefinder will
provide you the adjusted play distance based on the angle of decline or incline to
the flag. To learn more about Slope Mode, please visit our website.
◆To make it easier to range the flagstick, hold the Power (Range) Button down to
enter the Pin Lock with Vibration Pulse Mode. The rangefinder will vibrate and
display a flagstick icon confirming you have ranged the flag. You may need to hold
the Power (Range) Button down for a few seconds until the rangefinder locates
the flagstick.
◆Under ideal conditions, your Astra Optix™ Pro X-1 Laser Rangefinder can
measure the distance of reflective objects out to 1,760 yds. It can also measure a
tree out to 1,000 yds. and the flag out to 450 yards. The Pin Lock with Vibration
Pulse Mode 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 laser.
◆If the Low Battery Indicator flashes, 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.
