Tesoro Silver uMax Depth tests

[George (MN)]

You turned it down to 9, even though it was stable at 10. Please explain why? The higher the sensitivity, as long as it is stable, the better the depth. Did you check if it was stable even above 10? If not, why not do so? And you should want to check it at different levels of discrimination. Turning up disc on many detectors causes depth loss (% varies) but may make a detector stable at higher sensitivity.

I think air tests can help determine if a detector is defective. Also, air tests represent the coin depth that is possible in ground with virtually no mineralization. If you have heavy mineralization, you can probably figure a % of that for your ground. I figure 60% for my ground. Your posts suggest you have not air tested the detector??

We are just trying to determine if it is operator error or actually defective. Please let us help you by supplying more info. HH, George (MN)

P.S. the 10x12 would cover more area quickly, should be somewhat deeper & may do better with coins on edge. Still, it must be determined if the detector is adjusted improperly or defective.

digging a hole and placing a fresh coin into is just the same as an air test actually worst than an air test as the ground resistance will cause a weaker target responce. You can use salt water to make the hole and surrounding soil more hotter and then the coin will give a halo effect. Bill

Look at Today's Finds and view some of the stuff ModernMiner consistantly finds with his Umax in Cary, NC. I would say that it is a great detector based on some of the user comments and finds I have seen. Sounds like a good detector for the money to me.

Throw a 9"x8" coil on it and it'll act like a totally different machine - in a good way...

Ya I thought about doing away with the donut coil in favor of that one...



But I sided with the BAD A$$ 10 x 12 instead

Either way you come out a winner...

Here where I hunt I have used many detectors and If I hit a dime at 7 inches I am doing good. And when I do find one 7 inches deep you have to be really listening.
These guys saying they hit dimes at 12's sometimes I wonder if the coin slipped further in the hole when they where digging an they didn't see it?
Then again the dirt in New England could just be harder to get depth in.

Since originally posting on this topic I have hit a couple of clad dimes at a measured 9" with no problem. I think the fresh buried thing is your problem. The SilverU is a great machine. Monty

Either way, as there are plenty of opinions and experiences, this is a pretty impressive detector, especially in it's price range.

 

[Irontask]

The Silver Umax is a great metal detector.I agree with Skiwhiz that a fresh buried coin isn't going to show how this unit performs in the field.The aged buried coin matrix halo effect even with silver will give a greater depth.My suggestion make a coin garden for these test.Use the Silver in a old park for a week or two and confirm this with results from the field. Good Luck Ron

Deathhare, the deeper the target, the longer its been in the ground therefore making the halo effect (oozing of the objects properties into the soil) much stronger. So if you drop a coin into a hole it has zero halo. Try leaving it there for a few days and check again. I feel your disgust, had the same thing happen to me and my cibola, wouldn't get a quarter flat at 8 inches, I was pissed! I went back abt 3 days later and there it was, try it out.

What he said, with the halo effect, (Something you'll get from pretty much "any" metal buried for multiple years), your machine will find it, depending on the size and time underground, you could easilt get a foot of depth. (My deepest detected and dug item was a 1943 ww2 dogtag at 1 FOOT.) Even stainless leaches into the ground after a time.

GreenMeanie,

You have a very good point. New England is a 2x edged sword... a ton of history, but rocky as heck w/ iron saturated soil...

HH all!

 

[jharhed]

Thanks for the back up Zen, so I guess I'm not totally nuts

I just got a Tesoro Silver Sabre. Its pretty old, at least 10 years that I know of. I'll do some tests and
let you know what I come up with. It's only got the stock coil on it so I'll hope for the best.

I agree. My Silver Umax has been an outstanding machine, and I honestly don't think I need anything better.

I agree, Modern Miner.

I agree, Modern Miner.

Very nice BB.
I guess that Silver Umax is well worth that whopping $235 price tag after all!

[BuckleBoy]

Heck yes, Doug!


Been a long time since I have made as valuable finds like those. I've topped out in the $500 range last year--with some $200-300 finds... But one day I will be back in the running.


World Class digs there.

I haven't had the chance to hit any historical MD sites besides the old mine I posted about over in "Todays Finds" http://forum.treasurenet.com/index.php/topic,248907.0.html. I did pull an old coors
can out from about 10"-12" down with my ancient silver sabre. I've come across a bunch of clad
at the school yards I've scanned. As far as gold goes, my home tests have proven I need to buy a
Supertrack if I want to use a Tesoro for prospecting. I put a piece of 14k in the bottom of a 3&1/2" deep pot with my disc on 1 and it couldn't find it. Maybe it needs to be tuned ? I don't think it was
designed to find gold. No worries. Its my first machine, and from what others have said its a keeper.

 

[Keppy]

Yes, it is sad.
I felt very deflated and almost didnt want to do any hunting today after that.
I ended up finding a cool spot to hunt though had a good time anyway.

Im kind of scared to buy something else though and it not be all its cracked up to be either.
I heard some awesome opinions about this uMax before I bought it and it definitely swayed me to get one. Those opinions were obviously a little exaggerated or untested?

You have to go to a dealer and check out the detectors in person..." Most opinions are exaggerated."...... I found out you don't buy on other people's opinion's no matter how much expertise they have or how many years they have detecting they are always going to over state how good there detector is and that my man is a fact...........................................
