The Grinder Of Pars (Semi Crocked)
A lot of GPS units have a movable cursor acting as the pin.It depends how accurate you want/need to be.
Hitting it to the centre of our greens would see you 3 putting several times a round in summer, depending on the pin positions, normally it's much better to be short or long.
Laser is more reliable and accurate, trying to work out a precise distance to a back pin when you're nowhere near a distance marker is just guesswork. At least having a GPS that tells you distances to hazards and front, middle and back of each green is miles better than nothing at all.
Normally it's set on middle but you can move it to anywhere
So if the pin looks towards the back you move it in the general area and you have your more accurate approximate yardage..if that's even a thing
