Not sure if you want to hear this but im going to say it.
1st be in an area where there are gold rings. 2nd I do not hunt gold by patterns usually as I actually open my screen up as much as I can stand it. And third, dig. Dig Alot.
You can get Andys program for gold out of his book if you are hunting sites with lots of other targets and want to minimize digging. Im of a mind now that its better to hit you loacation first with an open discrimination pattern and then after you find targets that bug the heck out of you then make an ANTI program to block the crap your hitting alot. Gold comes in all over but if you want to focus on all the most likely gold targets then yes a pattern will do but keep in mind if there is gold there then there is gold in all kinds of shape and mix as well and you will just hit the most likely.
I have to say again. this is if the place is not littered with all kind of crap then use a pattern. But if you can, open up your discrim alot and let your brain do the thinking of what to dig. In one old area I hunt ( with no pultabs or few) I have found over 70 gold rings, and a gold coin, that many of came in way out of what I would of expected the number to read, but I focus on depth of object and sound then VDI number is almost meaningless in this situation at first or until I dig it up a bit.
If your newer to the machine, try a program at first, if you start finding gold in a spot you know there is more gold in then open your discrim up. and trust the depth, the fine target point on screen, and a good sounding target.
Hope that helped but Its very hard to tell about this unless you right there and I swing you over the targets im checking. I dig alot of trash too I should say, but I know the gold will come eventually.
good luck.
