rangefinders only provide a linear distance to 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 or arrow . Other features that are provided for
firearms are outputs that display either MOA adjustments, or inches /centimeters
of holdover at that specific distance . TBR eliminates any potentially significant
error, and provides a precise range for your aiming calculations . TBR is matched
to seven rifle ballistics groups and three archery ballistics groups, allowing use
with most popular firearms and bows .
HOW THE RX-600 / RX-750 WORKS
The RX-600 and RX-750 are top-quality 6x22mm monoculars that incorporate the
additional benefit of a state-of-the-art laser rangefinder capable of measuring
the distance of a deer-sized animal from 5 yards to 400 yards (RX-600), 500 yards
(RX-750), an inanimate object from 5 yards to 500 yards (RX-600), 600 yards (RX-
750), and a reflective target from 5 yards to 600 yards (RX-600), 750 yards (RX-
750) . The rangefinders emit 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-600 / RX-750 to the object
and back .
