I know very few full-timers and they are usually very reluctant to talk about their big finds. They also spend a lot of $ on gear and travel frequently, some spending 6 months in WA, six months on the east coast. I am semi-retired and if I am detecting, usually about 10 hour days, I try for a gram a day. Certainly not enough to live on, covers most of my costs and a few frothies. I have the very occasional nice finds but it all evens out. If I get an ounce a month working full time that's good BUT that's 300 man-hours, rain, heat, dust, flies, travel, duffer days, broken gear, blown tyres, fuel etc etc.
