Slingshot.
I hip mount my 6a with every coil except the small 5 inch. When on the beach using it, I have the Sunray 12 on it so I HAVE to hip mount it. What I use costs a little more, but I find it to be the most confortable. I got a utility belt at Home Depot ( or Lowes...can't remember where). It is black, and has both velcro and belt buckle on it. It has a 2 inch nylon belt that runs through belt hoops, and the loops are attached to the , which is tapered and wider at the back for lower back support. It also has padding which makes it good for comfort and support.
I can post a pic later...at work now.
As far as gold and jewelry, it works great. I mostly use the 6a in all metal mode and switch over to discrim to see if it is iron. Some of my gold jewelry gives the iron/mid tone bounce so you have to watch. Some of the smaller gold may not sound off in discrim mode but have a slight warble in autotune that makes for a diggable target.
I found a gold ring with it about a month ago, with the small coil. I was digging all mid tone and high tones. One good thing about the CZ's and the 3 tones is that if you are only interested in trying to get the gold, you can just dig the mid tones only. If I am on the beach, and there is lots of clad and it's getting near the end of the day and I haven't had much luck with the gold, I can save some time and not dig the high tones and only focus on the mid tones. I loose the clad and possible silver, but it is an option if you are running short on time.
