Just got mine fitted legally in vic and must be in line with headlights and not be past bumper or bar must be connect to high beam on a separate switch and must point forward.
I use to have a f1a4 with level three mods not Woody's other bloke and did find gold with it but to be honest in mineralised ground it's very noisy and to shut it up had to have the gain way down to the point where it had no penetration in ground was a frustrating machine and for a level 3 cost...
Can't agree more that's why I made a basic setup 50 nm box steel is not going to break and the old Honda fortrax 300 are built like a tank and engine is bullet proof.
