Micro Series Laser Rangefinders
with VAC™ (Vertical Angle Compensation)
Ballistics Compensated Precision Laser Rangefinder
MADE IN USA

Thank you for your purchase of the Opti-Logic Micro™ Series Laser
Rangefinder with VAC™ Technology. You’re about to find out what a
precision, Ballistics Compensated Laser Rangefinder is all about.
Opti-Logic Corporation introduced the first affordable, consumer laser
rangefinder in 1994. Since then, Opti-Logic has continued to lead the
industry with innovations such as:
•The FIRST patented, Ballistics Compensated Laser Rangefinder
(VAC™)
•The FIRST Laser Rangefinder with a minimum 4 yard ranging
capability
•The FIRST Laser Rangefinder with Automatic Rain Mode
•The FIRST consumer Laser Rangefinder to use Red Dot Targeting
Technology
THAT’S WHY WE’RE THE BEST AT WHAT WE DO!

Your new Opti-Logic Micro™ Series Laser Rangefinder is a Ballistics
Compensated Laser Rangefinder System combining a pulsed laser
rangefinder and a vertical angle sensor in an extremely lightweight,
exceptionally small, easy-to-use package. This ballistically compensated laser
rangefinder is especially ideal for archery as well as other applications which
may require precision uphill or downhill distance measurements. The Micro
Series hand-held laser rangefinders are capable of measuring distances to
non-cooperative targets up to 400 yards away, and reflective targets up to
800 yards away, depending on model, target size and reflectivity.
Incorporating a precision internal electronic angle sensor, the Micro Series
are also capable of automatically correcting for vertical angle with 0.5 degree
resolution using our patented Vertical Angle Compensation (VAC™)
technique. VAC™ provides a ballistically compensated distance to an uphill or
downhill target with a single push of a button. This feature is absolutely
critical for any shooting application.

Distance Measuring w/ Time-of-Flight Rangefinders:
• Opti-Logic Ballistics Compensated Laser Rangefinders emit invisible, eye-safe pulses of
infrared light. Distances are determined by reflecting the laser beam off an object and mea-
suring the round-trip time-of-flight of the laser beam to and from the object. The laser beam
emitted by the rangefinder is in the form of a vertical stripe of invisible light, which enhances
the rangefinder’s ability to hit thin vertical targets. The maximum distance measurable by
any laser rangefinder is determined by several factors including the size, shape, reflectivity,
and orientation of the object as well as atmospheric conditions. Color and surface finish of
the target also affect the reflectivity and therefore can influence the range as well. A good
quality target is a non-gloss (matte) object that is light in color and has enough surface area
for the laser beam to efficiently reflect back to the rangefinder.
• Vertical objects tend to make better targets than horizontal ones. White objects tend to
range farther than black objects. Target surfaces that are perpendicular to the laser beam are
better than surfaces tilted away from the rangefinder. Targets made of “retro-reflectors”
provide the greatest range capability.
• Retro-reflectors are made of special materials designed to reflect light back toward the
light source, for example, stop signs, street signs, license plates, and specially made Opti-
Logic retro-reflectors. Contrary to expectation, extremely glossy surfaces like windows and
mirrors do not make good targets, because they tend to reflect light away from the
instrument.

Basic Operation:
• Hold the instrument an inch or so from your eye and aim at an object through the view
finder.
•Press and hold the Power/Range “ ” button. A “Red Dot” will appear in the viewfinder.
• Place the Red Dot on the target.
• Release the button and maintain aim on the target momentarily. Read range directly on
the internal LED display. Holding the button down for more than 3 seconds will automatically
place the laser rangefinder in SCAN mode. Data will continuously update until the button is
released or up to a maximum of approximately 10 seconds. Using this feature will reduce
battery life.
• Read the target distance after the Red Dot turns off. The last reading taken will be
displayed for approximately 8 seconds.
Display Brightness Adjustment: (3 levels of adjustment):
From an angle less than -45° (degrees), press and release the Power/Range
“ ” button. Within 3-4 seconds, press and release the Mode button “M” repeatedly until
you reach your desired brightness level. The display brightness will change from Dim, to
Medium, then Bright and re-cycle, accommodating all ranges of ambient lighting.

VAC™:
VAC™ (Vertical Angle Compensation) is an Opti-Logic Corporation patented technique of
compensating the measured line-of sight distance to account for a projectile’s trajectory, and
displaying the optimum effective shooting range without the need for estimating holdovers or
entering complicated ballistic data into your rangefinder.
Mode Selection And Operation
NOTE: The “M” Mode selection is designed to activate ONLY when pressing the Mode “M” button
while pointing the instrument at a downward angle of 45 (degrees)or greater.
•Press and release both buttons, then immediately press and re-press the “M” Mode
button until the LED indicators on the back of the instrument opposite “YD” or “MT”
and “BC” are illuminated. Release the mode button and the instrument will turn off.
•Illuminating “YD” LED, activates Line-of-Sight Distance in Yards
•Illuminating “MT” LED, activates Line-of-Sight Distance in Meters
•Illuminating “BC” LED, activates angle in degrees
•Illuminating “YD” + “BC” activates VAC™ in Yards
•Illuminating “MT” + “BC” activates VAC™ in Meters

Changing The Battery:
• The waterproof battery compartment is conveniently located at the bottom of the
instrument. The compartment cover latch is located at the bottom and rear of the unit.
• Turn the instrument upside down. Using your finger or thumbnail, gently pry the battery
door latch (located at the bottom rear edge of the rangefinder) away from the body of the
instrument until it makes an approximate 90 degree angle with the battery door.
• Gently pull the door away from the bottom. It will be snug.
• Note the position of the door and battery. Battery Positive faces out.
• Replace the battery and door in the reverse order. MAKE CERTAIN THAT THE DOOR LATCH
IS 90 degrees out, before pressing the battery door into the housing.
• Pressing the battery door flush against the underside of the instrument with your thumb,
snap the latch back in place.

General Care:
Your Opti-Logic Micro Series Laser Rangefinder is a sophisticated electronic and optical
instrument, built to withstand a reasonable amount of handling. This waterproof instrument
can withstand a momentary “immersion” in water. Please use the same amount of care as
any other optical or electronic device, such as a camera, binoculars, riflescope, telescope,
etc. Keeping the lens clean will insure optimum operation and performance. Use a soft, clean
nonabrasive cloth to clean the lenses. Cotton swabs work well. Never use paper or other
abrasive materials. Dampen a cloth with either a very mild soap solution or clean water.
Gently rub the lenses with a dampened cloth. DO NOT SCRUB THE LENSES. After cleaning the
lenses, gently wipe the lenses off with a soft dry cloth. Use the same procedure to clean the
exterior housing. Although your Micro Series Laser Rangefinder has been designed to
withstand normal outdoor use, some common-sense precautions should be observed. NEVER
subject your laser rangefinder to shock, high temperature, or harmful chemicals or gases. DO
NOT use chemicals or solvents to clean your rangefinder. Chemicals, insect repellents and
solvents can damage the plastic housing and lenses of the rangefinder. If the rangefinder is
not going to be used for long periods of time, remove the battery and store in a cool, dry
place. Opti-Logic products are designed for many years of trouble-free operation.

Technical Support and Maintenance:
For questions regarding your Opti-Logic Micro™ Series Laser Rangefinder or if problems
persist, make a note of the instrument serial number and date of manufacture and call Opti-
Logic Customer Service at 931-454-0897, 8am to 5pm Monday thru Friday Central Time. If
your rangefinder requires maintenance, your Customer Service Representative will assign
you a Return Merchandise Authorization Number (RMA) and provide instructions for return-
ing the instrument for repair. When returning merchandise for maintenance or repair, please
be sure to include a brief written description of the problem with the unit.

Errors/Troubleshooting:
• When a new battery is installed in your Opti-Logic Micro™ Series Laser Rangefinder, a
diagnostic check is performed by the onboard computer. This check tests the basic operation
of the rangefinder. During normal diagnostics the three rear LEDs will flash one time and turn
off, leaving the laser rangefinder in the last mode in which it was set.
• When ranging a target, if the unit is unable to obtain a range, it will seem to “lock up”.
Should this occur, wait for the instrument to time out, then press the power/range button
again.
• If the rangefinder shows a distance of “0", the rangefinder is hitting an object at a distance
that is less than the minimum distance. Try aiming the rangefinder at a more distant object
to verify operation. If the rangefinder shows a “0” on all targets at all distances, then this
may be hardware issue. Call your customer service rep.
• If the instrument seems to “lock up” on extremely dark targets, this is an effect of the
automatic rain mode. Simply swing the aim of the unit toward a distant target until a range
appears, or wait for the unit to time out.
• If no reading is displayed and one or more of the green LED’s are not illuminated on the
rear panel, check the battery door to insure it is flush with the housing.
