12X10 coil??? Depth advantage???

[richs]

Hi everyone! I am just wondering if anyone would like to give us an insight as to the depth gain, and expected advantage of the larger coil?
I have the Lobo, and a Vaquero units. Is there a distinct advantage over the stock coils on these units?
I have read that there is a slight depth advantage,sensitivity seems good for the size, and the advantage is using a Tejon! (which I don't have!) Has anyone bench tested so as to do a comparison in the stock 9X8 vs 12X10?
Also, the coverage may be considered. I trust someone who has had experience in the field with one could enlighten us!
I'm sure others are wondering as well...thanks...

The only 12 x 10 coil availible for the T/V/C/LST is a double D coil (Tesoro doesnt have a 12 x 10 concentric for these machines). I Have not tried the 12 x 10 on the C or the V, but I have on the Tejon and all three machines are based on the same platform so it should perform similarly on all three. On the Tejon, unfortunately, I didnt see any increase in depth over the stock coil. But, if you have mineralized soil, you may see a depth advantage (double D coils see through mineralization better than concentric coils). What you do get, however, is greater coverage. I have not tried the 12 x 10 on the Lobo, so I am not sure how it performs on that machine.

Thanks for your help... Yes, I have heard that the coverage is better, which is understandable... but the depth? That is really a shocker!!! I thought a couple of inches more depth would be a given! Did you notice the sensitivity on the larger coil to be less that with the stock 9x8 ?
I have noted that the 12X10 is a DD... I am not worried about the DD coil vs the concentric coil.. We have little mineralization here.
I had a Tejon for only a short time... and altho on the same platform,it seemed to have more depth than the Vaq. or the Lobo for sure! I found it too sensitive in highly mineralized ground, when gold hunting (probably me!)... I had other units that worked very well.. so sold it. My hunting now has changed to relic type searches, and thus the questions.
Since you have the Tejon, have you also tried the 3X18 Cleansweep? I know it would not get the depth, ...I am just curious about other coils for the Tesoro units. I have the standard coils plus a 5.75 DD coil for my units.... Maybe it is time to add another one. I really appreciate your findings!...Thanks..

I tried a big coil when I first got my EL Dorado and did not like it at all, big and cumbersome for my hunting terrain. Maybe OK for beach area's. I got a shadow "hot shot" coil but went back to the standard. The standard coils on all my machines seem to be the right choice. I too was wanting more depth and is why I got the Vaquero.

 

[Rich in Rocky]

Thanks... That's the kind of feedback I need! I ,too, am happy with the stock coils, but always trying to get MORE! aren't we all!...

The sensitivity of the bigger Tesoro coils, in my opinion, is just as good as the standard coils. Yes, the Tejon has more depth than the V and Lobo, and it also hits harder on gold targets and coins/buttons on edge. If you are now primarliy a relic hunter, the Tejon would be the best Tesoro machine you could use, with the stock coil.

The 3 x 18 cleansweep coil is again, not any deeper than the stock coil but you do get great coverage.

In my opinion, the newer H.O.T. machines and coils are the best that Tesoro has to offer.

Depends on what you're looking for. The 8" coil is the COMPROMISE between a coin and all purpose coil. The 5.75" coil is a COIN coil supreme, with a compromise of depth between the 8" coil and the 4" coil. The 12" coil is a small cache coil that compromises as a coin coil under ideal conditions. As Barber Bill said, the 5.75" coil was an eye-opener for me.

 

[Diggler]

The 5.75 will be my next coil. But as Scully stated "The sensitivity of the bigger Tesoro coils, in my opinion, is just as good as the standard coils.", I find true as well. I bought the 12x10 as a cache coil and have learned it is extremely sensitive to small items. If not DISC'ed out, old, rusted thumbtacks sing out clear like a coin. But my experience is only with uMax. And I do get at least a couple inches more depth with the 12x10 than the 9x8. HH!

Hey... Great stuff guys! I have the 5.75 widescan now.. and wouldn't trade for anything!
Your input has answered a lot of doubts. I was hoping that the 12X10 would get me the extra depth needed on the Tesoros...
My question then to myself will be : is the extra depth of 2" worth the cost? and then the extra weight thing as well???.. I love the 9X8 coil, and with the 5.75 DD, maybe that is all I need on this unit. More depth, possibly use a different unit...
Does anyone have the 18" cleansweep? Gee I ask a lot from the members!

 

[Diggler]

I use the CleanSweep A LOT. But uMax. 6" on a dime is average. I love it!

Should be fine on the V. The preset gb models may or not have a problem depending on how they were set and the ground being detected. And then, it may or not be enough to be a major concern but is somewhat likely to miss being optimum.

Thanks BB.. I think that widens my sights again on the 12X10!..
Also, I thought I had posted a reply to Diggler...re: the cleansweep..
I think that the 6" depth is good... but was wondering about the Discrimination in trashier areas? I would think that the advantage of the wide sweep for location of targets would outweigh the problem. What about pinpointing?... Any 'quirks' with the coil? Glad to get so many responses to my questions!
thanks again and a Great 2010 to all!

 

[Diggler]

Well the CleanSweep is a DD so depth is consistent from toe to heel. Pinpointing is a breeze using the toe or the heel. Discrimination in trashy areas usually is not a problem. You really don't have to switch to AM/PP to find your target, and if things get extremely trashy, you can flip the coil up 90 degrees and use only the heel. Only quirk I have with the coil is really a quirk in the Cortes, as depth readings are about half of what they ID.

 

[Rich in Rocky]

Thanks on the info. That is similar to the Bigfoot that I used for a while. Only this sounds simpler, and also should work well in open field hunting! I have some shallower Relic fields to cover. Things are not usually deep, and Cleansweep should work well with the Vaq. Time to save up!
Hope others add to the thread.

 

[BarberBill]

The clean sweep is very easy to pp with, as mentioned right at the toe or heel. The pattern is narrow and comparatively long which helps to miss many of the trash targets. Mounted with the longer part to the rear makes it swing a bit lighter. Great coil for its intended use.

Thank you! another Super tip! I would never have thought of that!
I am really delighted with the response and all the help! Thanks again for all the help!...best...Rich

Some very interesting replies here, I'm glad I read this thread.

Rich, I think the Vaquero would hit most targets here in Alberta using the stock coil since we don't have the history to provide really deep targets here. Except of course if you are hunting filled sites, cultivated fields or beaches where targets can definitely be much deeper. The clean sweep coil would really work well for what you want I think, unless the area is real trashy in which case you might consider a 4" coil to get the separation and find the good targets between the trash signals. I've heard of guys using the clean sweep on end to pinpoint, which would be very accurate I imagine.

Anyhow, stay warm out there in Rocky Mountain House! This cold has to end eventually....

 

[Rich in Rocky]

Hey Scott... Good to hear you give some info as well! I didn't know you had/used the Vaq. or Tesro line!
As I mentioned, I already have the 5.75 DD which is GREAT! I just need the coverage, thought maybe I could kill 2 birds with the 12X10 coil, but the added weight and such???... still considering! The Cleansweep is probably what I need. With winter here , I want to do some research, and the guys have certainly been helpful! Keep warm yourself,Scott,and the rest of you... keep digging treasures while we pactice our snow removal skills!
