5x10 and 5.75 coil

[Rick N. MI]

Has anybody compared these coils with the Vaquero or Tejon. I'm giving a thought to get the 5x10 for my Tejon.

5x10 here, very good coil for the tejon!

I have a 5.75 concentric coil for my Vaq.
Great in trash, like the concentric over the DD type because I hunt some trashy parks with sometimes lots of old pop tops and the concentric is a bit faster and more efficient dealing with these things.

Also pretty lucky for me.
I don't use the Vaq all the time but I swung it a little more for about a week checking out this coil after I got it and on like my second or third hunt I found a tiny gold ring in a very large area.

Nice. I am debating to get the 5x10 dd or the 5.75 concentric.

nice coils on the Tesoro's hey

like I say to my mate expect it when you least expect it

good find and thanks for the vid.

Great vid.planning to order a 5.75 for my vaq in a week or two hh

I use the 5.75 concentric on my Tejon with good results, I prefer it over the widescan for hunting in the woods. I also have a 12x10 widescan coil, it's OK and covers large areas faster, but it doesn't have the "feel" that I like with a concentric coil. Buy lower rods for your extra search coils, it makes swapping them out a breeze.

Matter of fact, I have tried all of the Tesoro coils on the Tejón as well as two aftermarket NEL coils, both elliptical DD designs, and I have used all of Tesoro's 5-pin coils on the lower-frequency models.

It is difficult to provide a complete answer to your question without knowing the type of hunting you plan to do and the site conditions where you will be searching, so I'll just share my personal opinions from experience. Other than my two OLD Compass detectors, I have ten detectors from three manufacturers. On my three Tesoro's [size=small](a Bandido II, Bandido II microMAX and Silver Sabre microMAX)[/size] I keep a 6" Concentric coil mounted on each one of them, full-time. This is the so-named 5.75, but it actually measures 6" in diameter. On my other two brands of detectors I use mainly Double-D search coils except for two of them I have a Concentric coil.

For example, I mainly search old locations where there once were, but are no longer standing, structures such as houses, depots, stage stops, sheds, barns, stores, etc. Although they are gone, due to fire or demolition or tear-down to move them, left behind are many iron nails and other metal structure hardware [size=small](bolts, nits, screws, hinges, tin, etc., etc.)[/size] that needs to be handled and dealt with to gain best performance. I have found smaller coils excel over medium to larger coils on detector models that, by design, can handle these types of tough iron contaminated sites well.

A real-life challenge for any detector to try and handle is my Nail Board Performance Test. I have been using it since Memorial Day of '94, and in 22 years [size=small](as only ONE of several test scenarios I use that are based on actual in-the-field encounters)[/size] it has helped me, and others, learn about some of the strengths and weaknesses of different detectors or coils. In this case, how well they can handle, or perhaps not handle, dense iron nail environments.

In this case, here on the Tesoro Forum, let's look at an example of a Tejón with a multiple search coil experiences. I already know what different makes and models and coil sizes and types have worked best for me through the years in the environments where I go Relic Hunting, and I have been a devoted fan of several Tesoro models since 1983, owning my top-three favorite Tesoro's today .... and keeping the most functional and capable coil mounted for the urban and non-urban challenges I typically go up against, the 6" Concentric.

Last year we had a Welcome-to-Hunt Outing to three ghost towns in Nevada in September. These are open to anyone and they can use any detector they want, to which I add ... 'Good Luck!' One participant was aware of the abilities of some Tesoro models, and had seen some demonstrations I did on our 1st WTHO in May. He decided on a Tesoro Tejón and found a nice deal on a gently used Tejón 'package' that included the stock 8X9 Concentric spoked coil, and a few Double-D coils. Those included: Tesoro's NEW 8X11 DD, the Tesoro's 10" Elliptical DD as used on the Lobo SuperTRAQ, and a NEL Sharpshooter DD coil.

Let me add, if you don't mind, that many people in the hobby today have used or have considered using, a DD coil, quite often because they have hear good things about it from forum posters or a manufacturers ad, so they often have a perception, or perhaps we could say a misperception, of how a DD coil performs. Too often we hear terms like "knife blade" precision or "sees targets better in trash" or other encouragements of what they might be able to do, or how they might perform. or the EMF of the DD coil. One thing often not spoken of is just how well a coil might behave based upon how the detector circuitry is designed to work with different search coil sizes and types.

Anyway, I don't know what his personal experiences or feelings were at the time, but I suspect it favored a DD coil design. The night before our first ghost town hunt day at another site he had found a silver Barber dime. That's slightly smaller than an Indian Head penny, which was what I first located laying among the four iron nails back in '94. but it is also much more conductive than an IH penny.

He hadn't had the opportunity to really evaluate the Tejón and coils as he had just received it before the Outing, so we put the NBPT on the ground in the ghost town, and he mounted one of the Tesoro DD coils to check out the performance. He adjusted the Threshold and Ground Balance, then the Discrimination setting to just barely reject the four iron nails. Then he placed his silver Barber dime in the #1 circle in the center and checked out the Tejón/coil combination making the left-to-right and right-to-left sweeps across the entire Nail Board, using all four directions.

To ME, it requires 6 responses out of the possible 8 sweep directions to 'pass' this test, and I seldom use any detector and coil that can't provide at least 7 or 8 out of 8. First up was a failure. Honestly, you could say a total failure because when you only get 3 or 2, maybe 1 or 0 responses on 8 sweep directions, that's a failure. So, he switched coils and mounted the narrow Tesoro 10" Elliptical DD, checked the settings, and gave it a try on the NBPT. Once again, he was rather shocked at the lack of performance. Ahh ... the after-market coil must be the answer, so he mounted the NEL Sharpshooter DD and worked it on the test, and THIS TIME ... he was, again, discouraged by the almost total lack of performance.

Here we were, at the start of a 5-day Outing with three or four ghost towns to hunt, and he didn't have a smaller 6" Concentric coil yet. I told him that a 6" Concentric would be the best coil choice for that model, or most any good Tesoro. Then I encouraged him to try the stock 8X9 Concentric coil. Note that 8X9 size is very close to or larger-than some of the other coils he had already used, but they were DD types. I knew then that he would be surprised because that coil gave him 8 out of 8 hits! A smaller 6" Concentric would do better in actual tough site challenges.

Back to you posted question:

It really depends on the site you are hunting, the density of trash, and where it is a lot of ferrous or non-ferrous you will deal with. The place you'll hunt might be wide-open and all targets, good and bad, are well spaced. This is what readers don't know, but ... If you are going to hunt modern trash at playgrounds or around picnicing areas, etc., I would suggest the 6" Concentric coil. If you are going to hunt any places with a lot of iron targets that might be closely positioned, I would suggest the 6" Concentric coil.

I am a convert to the concentric's and I wish they just called them monos its much easier to type so Tesoro's and monos work, I'm not 100% mono but if not then small DD's are good also only coil I use over 7" is the CSC on any Tesoro. but I hunt jewellery and of cause what ever else pops out so nothing is to deep in this style hunting. so I don't need big coils and the small ones are more sensitive.

don't know about all the testing stuff its fun and something to do, and I put a vid up here and there on a test or 2, but for me I just go dig, if what I am doing isn't working I try something else, or better still somewhere else.

guess with time we get to see what works where and what conditions etc.. and do it again somewhere else, but every site is different and its good to have more than one tool in the tool box.

just watched the gold rush show looks like some nice little nuggets in Oregon Monte.

Tesoro's find stuff , why? probably because there is nothing to think about, and well I say if you cant get down for this target mate its time to go home, that's what I say to myself, and days on end with no gold can get to a person, but when that nice one pops out takes away all the pain, its not about money its about hunting and exercise and getting outside.

Thanks Monte.

It will the 6" concentric. To much iron all around.

I watch Gold Rush and saw the nuggets too.

Getting ready to get a new detector. Don't know what but I will always have a Tesoro.
