Have to disagree slightly with the negativity regarding distance finders. The skycaddy gives you an instant readout from anywhere on the hole to the front, middle and back of the green and so when I'm using it I can see its 156 to the front and I need to hit 147 to clear the front bunker. Quick check on the wind direction and pick a club to go. Job done.

These types of aids (Caddyplus is another) are far quicker and give and instant reading without having to wait for the planets to align and the flag to be visible. As for asking for club selection, I might ask my partner what he thinks but as my regular partner and I are at least a club difference in length I'll normally go on my own instincts. I'm mor likely to ask for a read on the green. Asking the opposition is a no no and I believe is loss of hole in match play
