DAY OF PLAY TEMPERATURE/ALTITUDE INPUT
(dP)
Temperature and altitude are two of the factors
used to determine TGR ranges; inputting the
current temperature and altitude will increase
the accuracy of your TGR measurement . This
feature is intended for players who live in low
lying areas and travel to higher elevations to
play golf . It isn't necessary to change these values if you
regularly play courses in the same geographical area .
