Tips for Using Your Rangefinder
◆ Your laser rangefinder comes defaulted to the Horizontal (Angle Corrected)
with Line of Sight distance mode. For archery or shooting, this mode will give you
the angle-corrected shoot-at distance to use. For Archery only, use the Archery
Mode (ArCH).
◆ If you turn off your rangefinder, it will keep the last settings used.
◆ This rangefinder also has Angle with Line of Sight mode. In this mode, it will
display the Line of Sight (LOS) value for 2 seconds at the top of the display
followed by the Angle value at the bottom of the screen. Shooters can use this
information to manually calculate long range holdover using a ballistics calculator.
◆ If using this rangefinder on the golf course, choose the Golf Mode (GOLF). The
Golf Mode will display the nearest distance value (Golf Flagstick) of a group of
targets that are within your field of view.
◆ Under ideal conditions, your Astra Optix™ Laser Rangefinder can measure the
distance of reflective objects out to 2,400 yds. It can also measure a deer out to
950 yds. 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 all reduce the overall ranging performance.
Cloudy days without fog, and without 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.
◆ IMPORTANT: The embedded Applied Ballistics® solver in your rangefinder
will calculate windage and elevation adjustment values up to 875 yards when in
the ABI (Applied Ballistics® Internal Mode). To take longer-range shots at distances
over 875 yards, press the “Upgrade” button in your App to upgrade to either the
Applied Ballistics® Sportsman® solver (up to 1,750 yards) or the Applied
Ballistics® Elite® solver (up to 5,500 yards). *The Elite® solver max yardage is
limited by your Astra Optix OTX-2400A range
finder’s maximum distance of 1,760
yards. If you already have an Applied Ballistics® Elite® solver equipped external
device, then you can use the ABE (Applied Ballistics® External Mode) and the
external device will provide the ballistics solutions to the rangefinder.
