Anybody Interested In That Little 4.5 x 7" Excelerator Coil?

It will work with the Quattro too...check my post over at the Explorer forum in the link below. Could be the ticket for those trashy areas where you want a little more than the "hockey puck".

Mike,

I hope to play with mine out in my test bed tomorrow so I will let folks know how it stacks up in GOOD ground using the Quattro.
 
Guys,

Just gave it a brief run through in my relic patch in my woods here in Southern Maryland. This is an established 5-6 year old test bed of relics and nails burried together and separately at certain depths. Now something you should know before we start. God has not created sweeter less mineralized ground than in the back of my woods. There is virtually no mineralization which allows me to run my detectors at full bore, something seldom seen in real life. I first had my Quattro set on All Metal with the sensitivity on AUTO. The first test was a good one for this little coil: a two-inch cut nail and an eagle button four inches apart down seven inches in the ground. The Quattro heard the iron but not the eagle button, then again most machines don't except for my MXT. Next target was a NY cuff button at six inbches. Once again, the Quattro read this target in both tone and VDI as weak iron. Next target was a bullet at eight inches......No problem here, a nice sharp repeatable signal with a VDI of 32. I knew the next target would be tough with a bullet at 10 inches. Once again, a weak tonal iron signal with corresponding iron VDI. Then for the suprise. I tweaked the sensitivity to 20.....Still didn't hear anyhting but iron with the first target. The cuff button at six inches now gave me a few high chirps but I could not lock the VDI on a positive number still......I would have dug it based on the "ify" signal. With the SENS set at 20, I hurt my ears on the bullet at eight inches. Even got a few high pitch chirps every fourth or fifth swing on the bullet at ten inches. Just not enough to lock the VDI in the positive but enough for me to dig. I still have many more targets to analyze but light was fading fast. Overall, I was impressed with the little bugger.
 
Interesting. I'll be hitting my test bed soon to see how it stacks up to the other coils and machines. Unfortunately I don't get home from work until after it's gotten dark (I have almost an hour drive with traffic) so it will have to wait until Friday.
 
Boy, that's pretty impressive. If your finding stuff even at 6 to 8 inches, I'd say it's a keeper, especially since it's smaller than the 10inch. Did you do any trash vs target separation trials? I'll bet it does great on trash separation too. Thanks for the great "real life" info. That's the kind of stuff I like, not just an air test.:|:twodetecting::cheers:
 
Right on Mike!!! I'd love to hear how it does in your test garden. Can't wait to hear the results.:twodetecting::| (Darn it, I don't have any place yet to build my own test garden. I need to work on some kind of scenereo out in the woods or something. I live in an apartment, and I'm afraid people would see me digging and dig up my burried targets. Well that's life in the big city sometimes.:|
 
Only on the two targets I have burried four inches apart. Have the two inch cut nail and the eagle button down seven inches. Quattro reads it as iron and misses the button. I have some other tests I will try this weekend.
 
Tomorrow I will be having a chance to try it. I'm really anxious to see how it does. I EXPECT that it won't hit all the targets...I have stuff that's 10-12" deep and the BEST of machines with a 10"+ coil can barely hit them, like my 10" silver dime...I don't expect it to hit THAT. But them that isn't the idea with a coil like that...the idea is that you can get into trashy or "tight" spots and "Git 'R' dun!" So we'll see...
 
Wow, that's a bummer. I would have thought that the Quatro would read the button too, but I guess not. I wonder if you put it into the high trash mode if it would read the button.? Are you scanning it from different angles as well? That could make a difference.
 
Mike did you read stumpr's post where he couldn't read a nail 4 inches from a button? That really suprised me, but I'm very anxious to hear your results, because I know my 5" excellerator coil can seperate very well. I've never done it under "test garden" conditions, but it seems to separate extremely well.
 
I did read his post. And while the button test may seem a little disappointing, I don't think it means much of anything. And the reason I say that is that I took my machine with the little coil to a place we call The Barber House today...it's been hunted by me and several other folks now for about 6 years...it's actually an empty lot about 2/3's the size of a football field that used to have 3 houses on it. They've been gone for years. What remains is a lot of rusty nails and some very tough hunting ground...roof tacks, nails, various other scrap and trash. But before the house were torn down we hunting the yards and got a BUNCH of silver...Barber dimes, quarters, Franklin half, Indians, Large Cents, buttons back to Colonial times, and much more. After the house were torn down it had to be hunted 100 times. By me and a half dozen others. Garrett, Whites, Minelab, Fisher, Nautilus, etc. Most folks have LONG since given up on it. Whenever I get a new machine or coil, I go there to test it. The SE found me an Indian and a Merc there in about 4 or 5 hours of hunting it, so that was SOMETHING. We'd all missed 'em before. TODAY, with the little coil, in 3 hours, I found more than I have found out there in the last 3 or 4 outings. There was iron in EVERY swing. But the little coil danced all around and in between it. Got killer depth too. First target out of the ground was a button from the 1830's that was about 8" deep under a root and surrounded by iron. Second was an old skeleton key. Next a wheatie...1912. Then a 1954 wheatie. Then a 1918 Buffalo nickel, a 1943 war nickel (silver) and a 1951 silver Rosie dime. Not bad for a place that's HUNTED OUT. Apparently not.

As for Ron's test, I also have a test bed in my backyard. With my Quattro in Auto it wouldn't hit most of the dozen targets I have there. With it at 20 it hit SOME. With it at 15 it hit them ALL. The Explorer is the same way...run it above 24 and most of the tragets go away. (It max's out at 32) The stock coil at sens 18 or 20 will hit all of them. Today I had the little 4.5 x 7 cranked to 30 in the backyard and it hit all but the silver dime at 10"...wouldn't get that. But it got a killer solid signal on the nickels I have at 7" and 10". That blew me away because the other machines don't. So there are many factors but I don't see Ron's button test as any cause for alarm. In the real world, it performed it's @$$ off.
 
Mike, that's a MIND BLOWER!!!, I'm thrilled that that little coil would seperate the trash at your house site so well and still get really decent depth. That's really exciting, because I know your Explorer SE, has to be the Rolls Royce of detectors, but the biggest difference seems to have been that the smaller coils "danced around the trash", as you said. The one that really blows my mind is your test garden thing. I'm so puzzeled that at the auto setting it didn't do so hot, at the sens 20 setting, (some of them) but when you turned it down to 15, ( I'm assuming your in manual now) it picked them all up. It sounds like what your saying here is: "Just because the sens is higher it not always goes deeper", or are you saying that because your had the sens so high, it was too noisy to pick them all up. Do you get what I'm driving at here? I guess what I'm trying to say here is: I've always thought the higher the sens, the deeper it will detect a target, but not so if your picking them all up at 15 sens. If I understand you right, that's a landmark set of information, and again, correct me immideatly if I'm wrong in what I'm assuming here. That's some very important info. I love your posts, and I'm thrilled that your coming over here to the Quatro forum now and then to share with us.
 
That's very interesting stupmpr. I wonder if you came at the target from different angles if it would make a difference on whether you could pick up the button, or do you think the iron nails is just masking out the button? Disappointing but interesting. Let us know how the other test stuff comes out. I'd be very curious. Marc.
 
You are EXACTLY right. Depending on the ground you are in, the EMF in the area, and the amount of iron and trash, running the sensitivity too high WILL lose you depth...sometimes even rendering good targets invisible. The proof is startling in my test range. If you ever get out with yours and find a deep target...something that you know is good and has some depth...try doing some experimenting. Before you dig it, change the sensitivity around and see how it does. Lower it down a notch at a time until the target signal degrades. You'll be surprised how low you get. Raise it up as high as you can and have it be stable, a little at a time, and see how it affects the signal. In clean ground, yes...more is usually better. In tough ground or in areas with a lot of perline interference or iron, it can render it useless. I'm getting ready to post on the Explorer forum again...more silver today with the "Mini-Me" coil. You need one!
 
"Wow Mike", I'll sure try that. I even read in one of Charles Garret's books, where sensitivity was one of the most important aspects of metal detecting, so that sounds "very important", to deal with that. It makes so much sense when you talk about a "known" target, so you know if it's reading it or not. Your not just guessing. Thanks again, Mike for the important insight and info. Oh, by the way, "I want one of those coils now". Sounds like a great coil with teriffic separation.
