TRUE GOLF RANGE (TGR) (GX-2i
TGR is an adjusted range that will compensate for uphill shots
that play long and downhill shots that play short . TGR
is calculated from the line of sight distance, incline or decline,
and current temperature and altitude . TGR 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 will play the shot as if it were 164 yards .
