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 rangeﬁnder'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.
