your target . TBR delivers the ballistic equivalent range to the target, accounting for
the effects of inclines or declines on the path of your bullet . For people shooting
longer ranges or in windy conditions, the Leupold team has included wind hold
calculations that provide a fixed 10 MPH full wind value . Other output values are
MOA adjustments, MIL adjustments, or TRIG values . TBR eliminates any potentially
significant error, and provides a precise range for your aiming calculations . TBR/W
is matched to each of twenty-five firearm ballistics groups, allowing use with most

HOW THE RX -2800 TBR/W WORKS
The RX -2800 TBR/W is a top-quality 7x27mm monocular that incorporates the
additional benefit of a state-of-the-art laser rangefinder capable of measuring the
distance of a deer-sized animal from 7 yards to 1100 yards, trees from 7 yards to
1300 yards, and a reflective target from 7 yards to 2800 yards . It emits a series of
invisible, infrared energy pulses that are reflected off the selected target back to the
optical unit . State-of-the-art circuitry and precision computing circuits are used to
calculate the distance by measuring the time it takes for each pulse to travel from the
RX-2800 TBR/W to the object and back .
