Hi Allan and welcome to the forum. The AT pro is a great machine to hunt with. Its not a entry level machine so it will take time to learn it. I have a AT pro and only just started learning the machine properly and have found some great relics with it. Once you have mastered the machine you will really enjoy it. There is a place in Durban that you can contact called Doculam to find out more about the metal detectors and price ranges. The gear you will need is a good sharp spade and a pointer. The pointer will save you lots of time in locating the target once you have dug the hole. Always remember to close thise holes again
As for restricted places, private property, heritage sites, historical sites those are all places to stay clear off. Private property you can only hunt if you have permission from the owner. I usually hunt open fields where there used to be alot of activities and public parks. (Unless there is a sign stating no metal detecting allowed but i have not seen this yet.) The guys also hunt beaches but i have not done this yet. Alot of research goes into finding old sites to hunt
Hope this helps abit.
Cheers and Happy Hunting
