falcon md 20 questions about finds

[therobertsmith]

Targets hit by creek and cluster of trees. Hits hard going down and staying on the object. I have tried different settings to try and make sure its good to go. So my issue is a lot that the falcon hits on is a bronze, copper colored covered in black crap. I hit a pocket the the wand goes crazy on everything.
So I decided to use a rare earth magnet and it sticks light to some but no strong. I have crushed some to see. The thing is crazy but wish it had a volume control.
So the stuff she hit on rem stick lighty to one side. Not sure if I shouod keep digging of just give up

Any thoughts would me appreciated

Sorry guys phone issues once again. Dropped to many times. So the area is loaded with quartz, what looks like lava rock, flat yellowish stone, just a big area of weird stuff. Most look as if it has been heated because of the way some look. Now, I panned some dirt and got a ton of black which the falcon detected coming away with the probe. The stones I washed have a strong tone going down and solid on but no tone away. The thing is a magnet sticks to some lightly but not all over. Now I know the falcon with hit on metals thanks to me wearing steel toed boots one day. Not cool. This time it was like "oh my pay dirt baby" I just grabbed some pics to post up of my positive response on the md20. What I did notice is black strands running at different directions like small cat hairs. I hate to break the stuff to actually see. Even the quartz looks bubbled and not like anything from the creek. Check the pics guys. I know it may not be gold but a solid tone going in and on tells me something. I have tried all settings and even adjusting the wand ring and still good to go.
Any home acid test to determine what it maybe? On a side note I did find big chunk in the creek. She is a dull grey and heavy but odd looking. I am definitely working in a highly mineralized area

Just a few. Hope they come out well.

All of these are hard pings going toward and on the item. Some are very heavy but some are light.

My only complaints about the falcon is I got to adjust the thing constantly sometimes and if it pics up a small piece I could dig forever.
Funny note: walking with it on I got a serious hit. A big hit. It was dark so I thought oh ya baby. The probe was almost 6 inches above the ground and she screamed. Started digging thinking finally. Well I guess I would be in the money if someone was looking for a headlight bezel for an old chevy. Also, don't wear steal toed boots when probing. Walking in circles sux.

*steel toed boots. I started to laugh because I knew someone would comment about "ya you shouldn't wear boots that are stolen. Hey steal, steel, potato, patatoe

That Falcon detects the gold very well, so what you're describing with a mild magnetic pull (and volcanic action in the area?) sounds like rock that contains some natural iron as iron will give a positive tone if there's enough of it in the rock.

The rock pictures you've provided, the top ones with the reddish dirt, make me think you're in an iron-concentrated area (volcanics [and basalt from volcanics] can do that) and as iron is a detectable metal, that will sometimes give a "hit".

I don't see any basalt in your pictures, but for your Falcon to hit positive, and for the magnet to give a slight pull, it may be iron concentrations that are causing your mystery.

All the best,

Lanny

It is a very iron rich environment. I have looked over the geological reports on our area and I am about 10 miles north of the Kings Mountain range which is stated as an volcano.
I love the fact I can go out and find something different each day and only cover 20 feet.
Thanks for the reply. The Falcon is definitely a nice unit and I am going to do some more work tomorrow to see what might come out of the ground. Hopefully the rain will stop long enough for some digging. I will keep yall updated.

A Falcon isn't really intended for use like a conventional metal detector. It has no ground balance circuitry. All you can do is stabilize the threshold by adjusting to ring position. Lots of stuff will set them off with positive and negative signals. Since mineralization changes constantly in the ground, trying to detect like this with a Falcon will eventually drive you nuts digging simple changes in the ground minerals. Falcons really shine when scanning ore samples and potential specimens around tailing piles and sometimes veins or stringers. Dennis

Yep, Dennis is right. I have had one for 3 years and like has been said, it goes off on anything metalic/ iron/ aluminum, silver ,steel etc . and so, I just use it on specimen rocks, as quartz matrix or , just to see what, if anything is in there worth crushing. Folks bring me their rocks to crush, .. I tell them that if the sample does not give a signal, I will not waste my time on it. Mostly the stuff brought in carries iron sulfides . Sometimes a good surprise with gold in quartz... luck.

I have the same problem.. I need to adjust constantly.. hot rocks are a real problem, they sound off all the time.. I have found that the tone is different though. I've had the unit since Sept 2015 and have not found really anything (yet) I live in an area rich in gold history, I also have found that the depth is shallow, maybe 3", this I tested on a small amount of gold that I buried ( maybe an 1/8 of an oz) I try to keep the ring half way between Black and red , again constant adjusting.. so if you find some answers please post, I'm thinking of getting a Fisher Gold bug pro and then use the Falcon as a pin pointer

 

[Goldwasher]

I have seen a lot of ore crushed that held good value and would not indicate on a falcon!

Is the gray specimen in your last picture really heavy for its size and non-magnetic? I am wondering if you should test for silver.

 

[Ragnor]

Pan the dirt and see whats in it. I had a signal one time and it just kept spreading out as I dug it. Took some dirt with me and panned it. Lots of fine gold. Sure wish I could relocate that spot, lol.
