Jeff Stephens, Richfield, Ohio (permanent) Chautauqua NY ( Summer)
currently use a Garmin S2
to determine yardage I utilize my Garmin S2 plus yardage markers on the course in addition to determining pin location (front, middle or back). The Garmin S2 does not give distance to hazards. So that is often a matter of guess, deducting the known distance to the green from the possible distance to the front of the hazard as well as the distance to carry the hazard.
