Delta 4000 air tests with coins and platnium ring.

[:Left4Dead]

Here is my testing results with coil off using a wooden ruler.

First test has defaults , discrim mode and sensitivity set at stock 8.

This is the depths where the vid still will read really close.


Zinc. 6-7 "
Dime. 6"
Nickel 7"
Quarter 7"
Platinum men's ring 8"


Now with sensetiity at 10

Zinc 7-8"
Dime. 7"
Nickel 7-8"
Quarter 8"
Platinum ring 9.

Note the ring was reading from 46-54. So it's a bit lower than tabs would be. Even if you ge a vdi that bounces 8 numbers apart its can still be a very good target...shoot it more valuable than gold!

Getting good vid readings at those depths is great.

Thats what I thought, they seemed much better than a few others I have tested. But the big thing is I did not even have it all the way up. I can run it all the way up in some spots.

well guys-i bought my delta 4000 in the fall of last year and i got the chance to use it twice before it got to cold and had to put it away for the winter.on my second time out i tried a sledding hill that i know gets hit hard by somebody because of what i was finding.by some fluke i found my very first merc. (woohooo)that was a thrill it was only about an inch down so i dont know how they missed it.GOD must have left it there for me though.thats my thinking.but i took it.anyway i've been using the delta all summer now and i have to say that i'm a little disappointed with its performance.i run in discimination all the time because there is simply to much junk to run in all metal.and i dont think i would ever get used to that humming in my ears it reminds me of a thousand mosquito's trapped in my headphones humming in my ears.i basically dig all high tones and pretty much ignore the numeric display because i've dug too many chards of aluminum cans that read 55 or 57 nickel because these maintanance guys are too busy to get off their butts and pick up the aluminum cans its just easier to hit them with the riding mowers and mulch them up.heck it does'nt hurt the mower at all.and i've dug quarters that read 82 dime.so i've basically given up on the idea of finding gold.it seems like i've dug a ton of pull tabs with repeating signals but if it was actually gold would this machine hit harder on it or would it just be the same as pull tab tone.as you can tell i never found a gold ring yet!the numeric display is good if the coins are right on the surface or even an inch down but any deeper than that the readings just are'nt that accurate and also any deeper than an inch or two i dont get repeating signals on coins.and i only get 3 inches the most for depth max with the 8 inch coil.could it be heavy mineral content of the soil thats causing it?i dont know maybe theres a flaw with my machine.i'd like to hear what other delta owners are getting out of their machines maybe i'm expecting to much?the big plus's its feather lite easy to swing for hours and battery life is good and the display is easy to read if it were accurate.input appreciated? thanks all-

hi nomad eather very high min. or something wrong with your delta.deltas, in norm. soil will get a dime at seven plus inches.sometimes you have to dig several hundered pulltabs an such to find a gold ring.

Nomad,

I really need to plant some coins in the ground and do the tests , and video them so everyone can see how they should work. Haven't found really any good videos on this detector. I have used a ace 250 for the first 3 months of the summer, and put over 200 hours in on it, found 2 rings both fake. I used the Delta now for about 2 months around 100 hours, hunting almost every day and weekends. Most cases tot lots and school yards. And some beaches. I have close to 25.00 in clad and one 1945 silver coin, war nickel and its only 35% silver:-(. I found another ring last week with the delta , again fake. But I did find and 1887 IH penny!! Any way I have not really even found a cool dime like you. The gold still has not found its way into my hands either.

Ohh and the platinum ring I wear is about a swing of 8 or so on the vdi scale, and bounced around on the ace as well, hard to say if i would dig it?? And platinum is more valuable than gold..it would be really hard to find.


What settings are you running in disc? Sensitivity?

Here is some ground testing it did.. kinda iffy? What do you guys think , is this normal.

Are you ground balanced?

I have found it to work well in a wide-range of sites.

What I think is that the results are about 'normal' considering you are sweeping over freshly buried targets. Get to 4" and then deeper and you can have some very impaired performance with many makes and models, regardless of their cost.

Did you sweep the area prior to 'planting' in the All Metal more or with the Disc. set at '10' to remove all metal that might cause target masking? I see that the Delta was set at the factory Default Disc. setting of '40' so it was rejection most all iron. There could have been some masking metal close.

Besides that, I am not a big fan of testing on fresh buried targets. Instead, I like to grid off an area about 20'X20' and then work it and mark all naturally lost targets. Carefully recover them and accurately measure the 'depth' distance from the target to where the search coil would have been.
