I bought a ZSearch from Rob a couple weeks ago for my 7000, looking for the weight advantage, also better pin pointing ability and help finding smaller nuggets which there is a lot more of than bigger nuggets, this helps keep the skunk off. All of this helps me as I am getting up there in age, almost 83.
So the purpose of this post is to say I am very happy with all the above and to tell you about my small nugget find to show that this coil will find small nuggets.
I was getting a fair amount of ground noise in the spot I was detecting because I was running the 7000 hot but got this slight variation in signal that was little sharper than normal, after 2 scrapes with my pick I was getting a sharp signal that I had to chase to get it in my scoop.
Finally I retrieved the small nugget? I call this a nugget because I found it with a detector, but really it is not even a picker, maybe a flake.
I weighed it on a Ohaus balance beam powder scale and it weighs .9 grains, not grams. Now this was not on the surface, it was down 1-3" as I made 2 pick scrapes to get it on the surface.
So I didn't get rich but I sure had fun, thats what detecting for me is all about. Thank for listening. Sorry I didn't take a picture of my flake.
