What is a SkyCaddie?
A skycaddy is a golf GPS system which accurately gives the
yardages and the layout of golf courses. You simply download your
course and you can instantly see how far you are away from the
green/pin etc. It is quite a grey area as to if these are allowed
in competition or not, because they are allowed in some
competitions, although in some competitions you may be disqualified
for using one.
