Tesoro 5 3/4 concentric and wide scan

[dirt lizard]

I would like to know the difference between the two. From what I see they both look the same and both are 5 3/4 wide. I'm going to order one but I'm confused on which one to get for my Vaquero. Thanks.

I do believe the one your looking for depends on soil conditions.
Wide Scan for mineralized soil and Concentric for mild soil.
Wide Scan coils have a bigger foot-print when searching... JMHO

The wide scan is a double D coil. They both use the same shell but the coils inside are different.

If was to open up the case on the 2 coils you would see that they are made different on the inside, the WS is the same as other brands DD coils. The windings on the inside would look like 2 D that are back to back making hot bar down the center of the coil. So the signal shape will be the shape of that bar in the center of the coil, which I think will give better target separation. If take a look at one of their bigger spider type coils you can better see how the WS is made and get an idea of what that bar from heal to toe of the coil looks like.

The concentric coil windings will look like to circles of wires one inside the other, one sending the other receiving. The signal off this coil would look like a funnel attached to the bottom of the coil.

I went through this same confusion on which to get for my Vaquero and Tejon, several months back. I couldn't get the experience I needed to decide by just asking questions, so I bought both and used them... I still use both concentric and widescan (DD) on my Tesoros, but greatly prefer the concentric wherever I can get away with it. The Concentric seems more "precise" in use, for lack of a better word. The concentric pinpoints more accurately, always in dead center. The concentric allows your Tesoro's discrimination to work most accurately and is more consistent in doing that. Those are the two best features of the concentric, and in areas with "mild" soil, it's the coil I want.

The widescan (DD) covers a little greater area, requiring less overlap than the concentric, but pinpointing can be a little off of where you think the target should be. Not far off, as it's only a 5.75" coil to start with, but it's obvious when compared to the more precise concentric. The widescan _does not_ discriminate as well as a concentric on a Tesoro. It will often never make a bottle cap go away, even as high as zinc cent area on your disc. The only areas that the widescan works better than the concentric, are in highly mineralized soil and small hot rock areas, and of course, the sweep area (coverage) is is nicer to use.

I have lots of bad soil areas where I search and some of them are just easier to do with the more forgiving widescan, but otherwise, the concentric is my favorite. Allmost all of my search areas are very trashy, which is why I like the 5.75" size.

SO - I would say that for MOST soil areas, you WANT the 5.75" CONCENTRIC.
If you just do bad soil areas, then consider the widescan.

I hope that helps you decide (get the concentric)...

Some of my sites are infested with bottle caps.
There is a way to tell what most of these things are using DD's and the screen units that is fast and efficient.
There are techniques to do this using Tesoros too but not as fast and efficient and a hassle for me because I don't have the patience and just dig them and using DD's they sound pretty good.
Using concentrics they mostly disc out, on DD's the disc is not as sharp so they don't.
I opted for a sniper concentric for my Vaq and I am supremely happy...those caps are usually a non issue for me now.
This one also seems to work better for me in iron infested sites, also.
It might not snake through junk with a long thin scanning field like a DD a bit better but the small size helps and the sharper disc is more helpful to me so it's a wash as far as I am concerned.
As far as depth in good soil my concentric gets very good results, in my horrible soil I hunt in now it goes as deep as anything else I currently use.

I have been wondering why the 9x8 concentric has be doing so well with target separation. So I have been doing some air testing an it seems to me that the 9x8 is only hot in that solid center area where it attaches to the detector shaft, and that D shaped hole area about the center of the coil. The 9x8 looks like a big coil but acts like a little one.

Now if kind of size that up and compare it to the size of a 5.75" coil I would say the 9x8 coil is about the same size, maybe a tad smaller than the 5.75. I have a little NEL snake coil and I am liking the 9x8 over the snake coil so far.

I don't have any of the 5.75" coils so I can't say much about them.

Thanks every one those answers filled more then my need to know. I learned something new on them as well. Concentric is the one.

The 5.75 concentric is the best choice - You will be very happy with it
