All golfers need help and when it's unobtrusive that's even better.
Not so long ago, the only support you got was a scorecard telling you the par and distance for each hole-not even any 135m distance markers or map warnings about a dogleg, fairway bunkers or a water hazard.
That was fine on your home course but when you played at new venues strong eyesight and sixth senses were invaluable weapons.
Of course the rules have been relaxed and most courses offer layout diagrams on their cards and some have very detailed booklets and pin placements to work to.
All these things remove the guesswork but not the poor shotmaking or bad scores.
