Placer Gold Deposits of Arizona 1972

I bought a house in meadview about 4 years ago.  Every couple months when I go there I try to get over to gold basin to do some detecting or drywashing.  It took me a couple years to find my first nugget out there and its been a couple of years since then and I havent found another.  I swing an SDC and I've read people have done pretty good out there with that model.  I find plenty of lead and boot tacks a inch or two down but not much deeper than that.   What settings are people using out there?  How deep down are people finding the gold?  Would I be better off with a  different model that can go deeper?  I'm not very confident in my abilities since I learned this machine on my own and have only found 2 pieces in the 4 years and dozens of times I've used it.  Any advice would be appreciated. 

This is an interesting little story about Mineral Park, Arizona.  It tells about a geologist who was told to find ore or be fired.  There is a bit of history about fine gold recovery also.

Hello Everyone,
   First, wishing you all a Merry Christmas and Happy New year, it's less than a week away.  
I haven't been out much, nor doing any videos.  I figured I probably need to toss something on my YouTube Channel before I lost all my Subscribers.... LOL This spot a friend and I have been working on and off for over a year.  It's a dry wash bottom and we are placering it.  We are removing the large boulders and gravel and trying to work the bedrock for nuggets.  In some spots we have attempted to vacuum up the gravels on bedrock and dry wash them, but to be honest the results were not hot.  Sometimes when you're into large gold nuggets, you don't have a ton of fine gold.  I'm not honestly sure if it was to do with the particular mining district and geology, but over the years we never found a lot of fine gold or small flakes/pickers to make it worth all the effort of Dry washing.  
It's seems more productive for the time we have to work it, to just expose as much bedrock as possible and metal detect it very well.  We normally use the GPZ 7000 or GPX 5000 as the primary detectors to cover the bedrock, but will pass back over the same areas much slower with the Minelab Gold Monster 1000.  That being said, we normally don't miss much, as the small gold is just not there and the Gold Monster really don't clean up much.  
Well enough of the chit chat, here is the video.  Hope you enjoy, if so, Subscribe to our YouTube Channel after watching to follow us.  
P.S.  Nugget ended up being just shy of 1/4 ounce.  Very dense, sluggy nugget gold is this area.  
 

I am on my phone so I can't figure out how to paste this, but a friend just forwarded a missing person report to me. A prospector went missing. He was just found dead, I believe with a gunshot. 
2 other prospectors have been arrested for murder and are in custody, they both are prospecters and stayed in Gold Basin.
I will try to post the police information when I get to a normal computer. 
Please delete this Steve if not appropriate. I am only posting because the murder was right in Gold Basin and victim and accused are all prospectors. 
The area is not what it once was and people need to use caution out there these days. this is now 2 murders in a tiny area and then of course the lethal shootout between the leader of the thievery gang that hit me, and a neighbor during a botched robbery.
