Silver Umax Target Separation

[Rainyday101]

I just got back from a 3 hour hunt in a park. This Silver just continues to amaze me at how well it can separate a target amongst tons of trash. I was running with disc just above zinc and the sensitivity in the red. In the real trashy areas you get pops and clicks from the disc. circuit. When I get this I just slow down and the silver picks the coin out of all that crap and gives you a nice clean round tone. I found 5 clad dimes and over 20 zinc pennies. Almost all of them were right in heavy trash. When you get to a trashy area just slow down the swing and work the area. When it hits a coin amongst all the pops and clicks from the trash you will know. If I would have had a TDI display the numbers would have been jumping all over the place as some of the areas were extremely trashy. I had a guy stop and check out my detector to see what I was using. He uses a Whites DFX and was really impressed by this inexpensive little beep and dig when I showed him a penny hit amongst all the trash. All I can say is wow, this thing rocks! I am using the stock 8" concentric coil. All finds were 1-4 inches deep with the oldest coin in the 70's and all were loud solid hits.

I am still thinking I need to add another detector to get deeper though.

I agree I love my Silver, Tesoro in general has incredible discrimination

You can equip the silver with a 12x10 concentric and get much better depth than the 8".You may pick up two more inches in depth with the silver.I have used a silver and they are super smooth detectors.Because it is a umax.If you choose a big concentric to hunt for deep targets with the silver you should not be in heavy trash areas.Lots of relic hunters use the silver.I found a very thin colonial button with my partners silver last year and was amazed at how well it picked up the thin small button.

Set it to where tabs slightly break up and you'll find some coins you missed.

Yea, I am tempted to get the 12x10 concentric, but most of my coin finds have been in trashy areas and this is where the silver really excels with it's awsome target discrimination. Now I have read on other forums that contrary to popular belief the larger concentric coils do give better seperation at depth. I have also read that shortening the coil cable to just the length needed, eliminating all the wraps around the rod, does wonders for depth. I am an experienced electronics guy and have my own solder station so I am fully capable of desoldering and resoldering the connector and tempted to give this a try.

Wow, thats the first time Ive heard about the shortened coil trick! Report back if you give it a try!

Rainyday, dont ask me to do the solder job, if you know what i mean, I find that as well it helps to slow down one nice thing is you can swing slow and it really gets nice sounds

Tabman over on treasurenet forum posted about it. He ordered an 8" concentric with the shortened cable from Tesoro for his Vaquero and started getting super depth.

Gunnar yea I remember your coil modification snafu. I solder a lot of connectors at work and have the proper solder station at home to do it. I want to see if I can find the manufacturer of the connector and order a new one so I don't have to unsolder and resolder. The key is to have a constant temp solder station and get in and out with the heat as quickly as possilbe. Desoldering and wicking out the solder can be a problem if you get too much heat there. I want a new connector so I can avoid that.

That just got back from another quick hunt with Silver at an old boat landing. Only found clad, but the Silvers target separation was key to finding most of these coins. Hit trash, slow down, pick out the coin signals. Works like a charm.

JUST NEED TO FIND SOME SILVER!!! I have a few spots I am eyeballing that will have the potential to yeild some silver.

Tomorrow early at sunrise the Tiger Shark hits the beach! I smell gold and diamonds!

It is a fact in electronics:The longer the conductor(coil wire)the greater the resistance in the circuit.The greater the resistance(flow of electrons)The less amps that are able to flow in the conductor.This is a law of electricity.You can see this law with the formula for electricity with the main formula e over i =r or e x i = w ( i= amps) w= watts r=resistance.Anyway if you were to run wiring in your home it can only be so long.As the wire gets longer the diameter has to increase because of the long run.I used to do electronic and electronic controls.So the theory of your thinking is correct.

By all means let us know how this works! Just had one of those "duh":moments-was thinking how hard it would be soldering the wires back INTO THE COIL! There is a connector end!:blush:

Yea Spirit Relic I agree with you on the resistance, but the length distance removed has minimal resistance, so little that for that amount removed your average multimeter could probably not even notice the difference. I am guessing a tenth of an ohm or less. The voltage drop across this little resistance is minimal. I think that it has more to do with impedance to an AC signal. You create a coil wrapping the wire around the rod and that is creating impedance to the transmit and receive signal. Keeping the coil lead short with no wraps removes this AC impedance (inductive reactance). My guess is that probably has more to do with it. I just need to time to tackle this and want to get a spare connector before I do it.
