FLAG LOCK TECHNOLOGY
Flag Lock technology is always activated and will identify the
pin from the obstacles around it, like trees and bushes, and
use the information to accurately locate and lock on to the pin .
When your GX rangefinder successfully locks on to the pin, the
flag icon will illuminate and the display will lock until POWER is
released and pressed again . Other brands leave you guessing
if you're locked on to the pin or the tree behind it, but our
intelligent Flag Lock technology is designed to calculate multiple
ranges in order to identify and lock on to the flag the first time,
every time . The GX-6c eliminates the guesswork and guarantees
an accurate range to the pin .
PRISM LOCK BEEP
Prism Lock is always activated and will
automatically detect the presence of prisms in
course features when scanning at a distance of
30 yards or greater . When using Scan Mode to
range a course feature with integral prisms, your
GX rangefinder will produce an audible beep and
the Prism Lock icon will be displayed along with the measured
distance . If True Golf Range has been activated, the TGR distance
and club selection will be shown . If True Golf Range has not been
activated, the line-of-sight distance will be shown .
