Sweep speed tolerance (1236 or Cibola ?)

[margiop]

Hi folks,
Italian detectorist needs your help.
I am looking for a medium priced MD that is able to hunt between a lot of little and big iron (First World War battlefield).
One important skill is the sweep speed tolerance, I need a MD which is not affected by sweep speed.
The choice is between Fisher 1236-X2 and Tesoro Cibola, that's why I post to both forums.
I know that they are both great in iron, they have a good choice of coils and they don't cost an "eye oh the head".
I read a lot of posts, it seems to me that Fisher (12-) is a little better than Tesoro regard the sweep speed tolerance. But Cibola seems to have more depth.
My soil is without or with low mineralization.
Many thanks to you, this is the best forum, period.

Hi, I have had and used both the 1236-X2 and the Cibola. I prefer the Cibola, but if you are hunting for iron I would get the 1236. The Cibola has some iron discriminated out even at lowest disc. settings. In other words the Cibola doesn't have a true all metal feature. Sweep speed doesn't seem to bother the Cibola, you can swing it fast or slow, and same goes for the 1236. Both are very good machines, with the 1236 being a better iron finder. Steve.

Thanks Steve for your kind answer.
In your opinion, which of the two has the best target separation skill ? And which is the deepest coil for coil ?

In my opinion I find the two are pretty equal in seperation and depth (both being very good). Being I am a coin & jewelry hunter I prefer the Cibola, it discriminates the iron out really well. As with most Fisher's the 1236 will still sound off on large iron even if disc. out. I know some folks here on the Fisher forum will say that the Tesoro's are cheap plastic made machines, but they are not, they are well built very light and have a lifetime warranty. And Tesoro stands behind what they sell. I am not saying that Tesoro is better than Fisher, but I do know they are great machines. Steve.

The 1236 dosent seem to be bothered too much by sweep speed the cibola on the other hand in my area takes a slower sweep speed to obtain depth.also the 1236 will pull lower conductors like brass shell casing and such out of the iron as good or better than anything ive seen in 20 years of hunting relics.

ive been using the 1236 for about 5 years now for my heavy iron hunting.

You cant go wrong with it.

Thanks Keith. What do you mean by "heavy iron hunting" ?
That you look for big iron relics or that you hunt between a lot of iron ?
I just search brass cases and similar items between thousand "grenade chips" and iron rubbish, I don't know how to tell in English.
So the most important skill for a MD is to erase iron still listening the good items.
Maybe a little coil could do the job, how do you compare 5.75 cibola's coil to 5 fisher's one ?

While the Cibola is a tad more sweep tolerant than the Vaquero the 1236X2 is the best choice for sweep speed tolerance. In fact a fast sweep over a deep target improves the signal response and at the same time will cause some of the troublesome iron to be eliminated.

Once you hunt around large iron with the 1236 and see what it can pick out in those conditions you will be spoiled for life.. Like Keith said, for heavy iron hunting the 1236 is hard to beat.

One more thing about the Cibola, when "super tuned" by cranking up the threshold knob for better signal response on deep targets it becomes an iron loving animal. At normal levels however it is a typical Tesoro around iron.

For brass and lead in non trashy areas the Cibola might be a bit deeper but for hunting in heavy iron infested areas the 1236 has the edge in my opinion.

I've owned and used both,the Fisher 1236x will lock on a target a lot better than the Cibola.In my ground conditions no comparison the 1236X has better depth.I use a Five inch coil(separates very well) and have recovered silver dimes over a depth of five inches.The Fisher is balanced very well and light and can be hip mounted and placed in a rainproof pouch in bad weather.These units used are much cheaper,hint check out the classified section.

 

[Keith Southern]

Ok heres what im trying to say the 1236 will pull low conductor brass and such non-ferrous items around large iron and small iron with relative ease.the large iron usually will repeat one way but not the other and it will have splattery sound the small iron isnt even an issue ive pulled military buttons out of holes with nails in the same hole in places ive previously hunted hard for years.just remember when hunting in thick iron turn the silencer off it will not allow the low conductor to break through the iron if its on.plus ot seems to reject the large iron better being off giving a broken signal.

I never turn the silencer on period!!

The 5 inch coil is phenomenal and about as deep as the 8 but lighter and twice the seperation in the dense dense iron.

truly one of the finest fishers ever made as close to perfect as a detector can get good depth and fantastic target seperation and iron handling.

you can get targets with the cibola but its not in the same league in the iron handling

one of my favorites along with the I.D. edge which if you want target I.D. its about the same as the 1236 but with a accurate meter and tone I.D and its amazing with the 5 inch on it.

Sorry I had to bring up the edge but its really opened my eyes here lately.

Feel free to respond with more questions.

For gosh sakes be careful as old mines will end the hooby for you.
1235X which was improved by the 1236 was and still is the best unit for planted hunts so that ought to tell you something relative swing speed tolerance...
Probably a toss up relative the iron thing but the audio of a Tesoro lets you know its iron...
I know these are old units but the original King Cobra or GMT by gold mountain certainly excelled in the conditions you describe...

 

[margiop]

Many thanks to all !
I will buy a 1236 with a 10,5 coil. I will add the 5 inches one to cope the worst conditions.
If I will find a good bargain on a Cibola I will also try it.
I know someone here in Italy that uses the Edge, I will ask his opinion.
Many thanks again.

After reading your post margiop, I think I see what your looking for. I run both the 1236X2 and the Cibola. It's not so much the iron scrap but the brass cases and possibly other non-ferrus metals that you appear to be looking for. The 1236X2 has another position on the disc. knob that allows for ignoring most small iron or at least causes it to sound off as snap and crackles while allowing brass, aluminum, etc to come in pretty clear. It still has a taste for some larger iron and will still sound off more solid on it. Under those conditions, I'd choose the 1236 over the Cibola. Remember that munitions (even old ordinance) were designed to kill and maim so dig safe, happy hunting, and good luck.

Thank you, Stoney, you are right, it is just my kind of search.
The most important thing is to avoid little grenade chips, without having a lot of sensitivity on small objects, the smallest are coins or medals, all the other items are certainly bigger.
I have to cover a lot of ground with a big coil and a fast speeed, but there are a lot of places where i need a slow motion speed, maybe also with a little coil.
Again, as you correctly stated, I don't need to reject copper, aluminium, foil or other modern trash, I dig everything excecpt little and middle iron, but I will dig big iron.
Sooner I will post photos with what I search and what I reject.
When you told me about the disc position in 1236 you were talking about the iron discrimination ?

 

[stoney56]

Correct. By rotating the disc. knob all the way to the left you'll be basically in all metal mode. Turning it further, you'll hear and feel a click as it goes into what I call iron null. It will eliminate a lot of iron and small nails (for the most part). I find though that larger nails still tend to show up, so I don't know what's on your sites that might make it through the masking.
I use it more in competition hunts and it does has a fast sweep speed. Adjusting the sens. down a bit will also help with shallow or surface iron that may get through as well.
A larger coil may also help get to the deeper targets while eliminating shallower targets. However, if the sites you're hunting haven't been disturbed by earth moving equipment, etc., a lot of what you seek should still be in the upper layer of surface to about 4-5" with a few exceptions.

 

[margiop]

Thank you Stoney for your answer.
I have another question about the 1236.
The 10,5 coil seems to be a concentric one, even if it has a strange shape on the receiving loop, similar to a DD loop.
How does it affect its performance ?
Do you thing it could be a great idea even in ploughed fields ?

 

[stoney56]

To be honest, I've never used the 10 1/2" spider coil. It's my understanding that it would probably increase the depth by an inch or two. It's more designed to cover more area per sweep. It may also allow for some larger and deeper targets to sound off. I usually stick with the 8" spider coil for most purposes. I'd also say that the 10 1/2" would probably do well on plowed fields but for small shallower items, you'd probably want to raise and operate that coil a bit higher off the deck. JMO

 

[Ron from Michigan]

The 10 1/2 isn't a DD coil.The coil bracing is different.The larger coil has a wider scan and will improve depth.The larger coil does add weight and isn't as sensitive or as fast of a response on smaller coins.I have never used a 10 1/2 inch on my 1236x,but have used these coils on CZs.
