I am currently in training, and start in August

Anyway, we learnt about PND's last week, and I would like to ask the following questions.
Do you issue PND/FPN's, if so how often?
If you dont issue them often, why?
What is your stations unwritten policy on handing them out? Do you follow this?
Who do you give them to, specific incidents, or anytime you see any kind of incident?
Thanks peeps
