Help Carl or anyone V3 Question

What do you think was happening with my new V3.
First I would consider myself an expert detectorist with 31 years experience with all whites machines. My latest is the DFX with D2 coil.
I went out for the first time after playing with and reading everything I could find on the Internet about the V3. When I loaded the stock Coin/Jewelry program the V3 went crazy sounding off with the stock D2 coil in the air. I reduced the RX Gain from 8 to 2 and Discrimination to 78 and it became stable. I ground balanced and checked ground balance. I then checked the sensitivity probe. It read Signal 8%, Noise 0.1 and RX recommendation of 15. I thought that this feature was to help find the best settings for the area? Why was it so off 2 from 15. The area has a normal power line about 150 yards from where I was. The site is a rural little town with a church, school, post office, a half dozen houses, and two bar and grills. A half mile away is a gravel pit. I was hunting the church yard, the house next to the church has aluminum siding on it . I noticed I did not find anything more than 4.5 inches down which was a nickle and a few shallow clad coins. This site dates back to late 1800's and is my first time hunting it after finally gaining permission. Other observations were a lot of nulling in the threshold which means trash and when the coil would bump something it would sound off. I also noticed on shallow coins I could not get the analyze waves to be nice and consistent to indicate a good target even-though the sound and VDI were good. After 2 hours hunting I went home which is a half mile from the site and tested it in my yard. I was able to run RX at 15 and Disc. at 80. I did a few air test and it worked perfect. Does anyone with experience with the V3 have any thoughts. Thank You.
 
That sound very similar to what happened to OKIEROY who just posted with a bad coil. It acted bad shortly after he bought it and then he brought it over to my house to look at it and it worked perfectly for me. He took it home and bad happenings again. :shrug: He called White's and they replaced the coil, he said all is well now. Do you have another coil to try? It could be any DFX/MXT/M6 coil.

You could take it back to your dealer and have him check it out.
 
If you hit the coil at home would it go off? if it does then the coil maybe bad other wise you may need to off set the frequency a Little and see if that settles it down.

I have had a couple areas where I had to turn the Rx way down although the recommended 15 seems to come up more than any other recommended number settings. I also have had to go down to 2 in these couple areas. Then I'll sometimes get into the frequency offset - also I have had to change the wireless headphone channel. Then will do the reconnect sequence. Also, if in coin & jewelery, knock the discrimination setting down but that was my preference and not whatever the interference was. I was able to tame it somewhat otherwise it drove me nuts.
I did later find that in one of the spots there was underground electrical power. There may have been other interference unknown to me. I also found there was lots of iron junk up to some rather large pieces of whatever it was.
I would have liked to try a small coil like the 5.3, but I been trying to hold off to see if Whites comes out with some new coils due to the introduction on the Vision/V-3
There were probably some other settings I tweaked on but don't recall at this moment. Did pick out a few coins but no silver last outing.
 
Added - I recall I had to set the ground balance locked - no auto track due to all the iron.
And I know there is something else but I'm still having that forgetful moment.
 
I'm curious...why hasn't anybody tried the stock coil off from the DFX and put in on the V3.... The D2 is for high mineral.....I'm surprised Whites didn't just put a standard concentric coil....and at least you'll have a choice to buy the D2 for high mineral ground if you have it or the Super12" coil for low mineral...
 
Can Anyone from Whites comment please. Thank you
 
something you may wanna try for extreme interference....

I would click on sensitivity and hit zoom jack up the preamp gain to 15.....pull trigger twice to log out ...your machine should be going banana's now arrow over to transmit....pick single freq. usually the 2.5 will be quiet and smooth....Look for deep silver and Tad Nabit had a good tip about locking the GB.....

Make sure your cell is left in the car....or at least 3 feet from control box.....

Happy Trails

Generally, V does pretty good with EMI, but there have been reports of areas where it just doesn't work well. Did you try adjusting frequency offset? That's the very first thing, then sensitivities, then single frequency modes.
