Has anyone used the concentric coil for the Explorer?

I have one I bought last fall that is the 8 Excellerator inch Concentric coil. I was only able to try it once last fall and just starting to use it now again. This coil runs so smooth and I can up my sensitivity to max at time and as low as 26. Not sure how deep it will go, but it looks very good. Separation is real good too with this coil and found some wheat pennies I missed with the stock coil plus a silver Rosie last Friday. I see where I can swing this coil faster too as it runs much smoother than the stock coil, but I know I have to overlap my swings more to cover the deeper targets.
What I need to do is some actual target comparison with one of my hunting buddies with the stock coil.

Looking foreward to your report.

It will have some depth advantage over 8" DD of course and probably better separation at depth some places. Maybe also better and clearer hit on coins.

Very interesting.

Yes there is some of these coils out there, I got mine off E Bay for $95 that was new. I like the way it works and hope it is not missing target being it runs so smooth. I used it today for a while at a old farm yard that I have been over before and the one area is very trashy. I did dig a few of the zinc fruit jar lids that were a good 10 inches deep and gave a good signal. I got a old brass Standard 6 Lever paddle lock, a key chain that looks like a arrow head that has Anaconda on it in big letters and still had the chain on it and a 1928 Wheatie. Every signal was very good and it seems like the iron signals were quick low tone and back to a good threshold fast on my SE, much faster then the stock DD coil is.
Also Steve if you are reading this I did the test you wanted and found with the nails on top of the quarter I can hear a high pitch tone of the quarter in with the low tone of iron. On the dime it would just give the iron tone and the nickle was different and bouncing around. I run ferrous tone and the sensitivity was at 28 and seem to work good.
I was hoping more that have the 8 inch concentric coil would have posted their finding with this coil, must like it as you don't see any for sale.

Thanks, Rick. The dime is really hard to get under nails with the tests I have performed on detectors.

Back to the same place today to see what else I could do with the Concentric coil. This was the area in back of the farm house where I had been before with the Sovereign and the Explorer with the stock coil and the joey coil and couldnt find anything more. This area has a lot of iron and some pieces of alum siding from when it was sided year ago. I ran the concentric coil and run my iron mask at 31 on the SE so I could hear most everything. Lot of low tones in the ferrous tones i was running and listen to all of them and try to pick out some that had a high tone in with them and worked it from several directions. I got 4 wheat pennies and a 1918 Merc by doing this. There was iron in the hole with each of these, but I could hear the squeak of a good target even though the visual ID was not right. The one wheat penny read in the middle of the screen, but had the high tone of a good target. After each good target was out of the hole I would either get a null or a low tone of iron. The coins had to be on top or beside the iron. The only ones I didn't dig were the one with the high tones and the cursor was on the very bottom of the screen as they were the pieces of tin cans and rusty bottle caps. I had to go slow too being there was so many signals. I am starting to like this 8 inch Concentric coil more and more and one I think I will keep.

Thanks.

Its obvious that you like it, good report.

Allways wondered how a CC coil would do on the explorer, may be the same for the sov.

I have tried the detech 8 inch concentric coil on my explorer SE and also on my old explorer 2 . The depth is not too good it looses 2 inches at least on coin depth over the standard minelab coil. It has no apparent advantage over the standard coil.. I have found the detech excellerator coils work great in the wet grass though where as the SE coil falses off all the time in the wet...... Thats the only real advantage i can see with the 8 inch concentric.. Works great in the wet but has poor depth....4 inches is all i can get with the 8 inch concentric.....

I wonder if you had a bad one if you didn't get more than 4 inches on a coin. I been digging wheat pennies this week at a farm site I been over the EX II with the stock coil and the Joey. This area is trashy so I run it ferrous tones and iron mask at 31 so I hear most everything. These pennies and the merc dime I got were all on top of iron and I know they were from 6-10 inches each one of them.I got the low tone of iron or a null and could hear a high tone of something else and working it got a good signal. I only got a null or a low tone once the coin was out of the hole is why I say they were on top of iron. Maybe it is because I run the iron mask at a 31 instead of a disc pattern so it has a chance to see the coins. I got a brass lock also over 12 inches and gave a great signal with the detech 8 inch concentric coil. Like I have said before I can run the sensitivity higher (26-32)too and it runs a lot smoother than most coils I have tried too.
I am going to have James ND try it and see what he thinks too on this coil.
