FUNCTION 2: TRUE GOLF RANGE (TGR) (GX-4 WITH SMART
KEY INSTALLED ONLY)
True Golf Range is an adjusted range that will com-
pensate for uphill shots that play long and downhill
shots that play short. TGR is calculated from the line
of sight distance, incline or decline, current tempera-
ture and altitude, and will display the adjusted range
the golfer should play to. For example, if you have
a lie 150 yards from the pin, but the green falls 6
degrees above your ball, you should play the shot as if it were 164 yards.
