Are you a laserer ?
Why are you going on about yardage books ? Gone the way of telex machine and VHS. GPS.
GPS is a 1s second glance. So a saving of 9s (assuming your 10s per laser is correct - time someone next time you have the chance). Thats still probably 10 minutes per fourball lost to lasering. No lasering - round 10mins faster on that component alone.
Our club's slowest player uses his laser, then puts in back in the bag and gets a hand held gps out. Then stands there staring at the flag!! He almost never plays the shot with the first club he pulls.
The staring vaguely into space has been copied from the Pros on tv. They stand on the tee and take an age to play... OK it's for cash, but they've played the hole several times in the previous few days, so they've seen it before
Blooming get in with it!!
