Probably the only one who knows is you. It depends on whether you plead 'guilty' or 'not guilty'. Then there'll still only be one person who knows what your outcome will be, The Magistrate. Also depends on whether you've been charged specifically with playing with dangerous toys since your childhood, how many other times you've been in trouble with The Law generally, whether you're employed, whether you're married, whether you're a member of an OMG (sorry Club), whether you wear thongs to Court and most important of all why the devil you had possession of a taser.
In my humble opinion, you're up the creek without a paddle as there isn't much of an excuse for being in possession of a taser (unless you're a cop or a lion tamer).
I felt a bit sorry for you as nobody wanted to reply to you and give you the bad news.
I'm not a lawyer but I've had a lot to do with them.
