Metal detector reviews Tesoro Cibola field test

Tesoro Cibola

I met with Steve at a local field which has produced some nice Roman finds Many machines can be unstable here Steve uses a Tejon, this showdown would be an ideal test to see if the Cibola's performance is really matched to the Animal.
The set up was simple, switch on, turn the sensitivity up to 10, press the pin point button and set the threshold so I could hear a slight hum, set the discrimination to the Iron position...and search.
The Cibola ran very smooth I was impressed on how well it behaved, high sensitivity caused no problems at all, even when turned well into the red section. On this site we run the Tejons at 6 to keep them tame, the Cibola's Iron rejection was fantastic, I felt the pre set "Iron" mark was a little high so I lowered it slightly, now it was set to how I wanted, I could hear the iron as a broken sound, a good target was always smooth and repeatable.

Having experimented with the discrimination I was starting to realise how different the Cibola actually was. With a disc setting of zero it would only reject the smallest of nails as you raise the setting it started to reject bigger Iron without loosing small targets, I can only describe it as "progressive" iron rejection. I found an Ideal setting was between the minimum and the word "iron", when checking a signal you can confirm the target by simply thumbing the disc to the Iron and listen for the change. What Tesoro have actually done is given the user a bigger scale or "finer tuning" of the Iron rejection,which will be a real bonus when searching ancient sites.
Throughout our 3 hour search there was not one occasion where the Tejon out did the Cibola, every target was checked, depth was the same we both got caught out on the same pieces of misshaped large iron, We felt the Tejon gave a harder hit on very small and deeper targets, the Cibola gave a soft quiet tone.
This is where our next discovery was made.

The threshold tone was originally set to a slight hum(with the pin point pressed in), which gave a nice audio indication of depth, However if it was turned up the Cibola was transformed, small and deep targets were sharp and loud, the field was almost alive with clicks and spits, this well behaved machine had just turned on the attitude, in fact if the threshold was turned fully up the circuitry became unstable, its almost like a second sensitivity. One disadvantage of running a high threshold tone is that the pin- point VCO is not so precise.With a little practice you can find the "sweet spot" where there is a fine balance between a loud and usable threshold.
My Cibola finds consisted of 1 Roman,1 Charles 1st hammered, 2 Strap ends, at least 15 pieces of assorted lead and dross, not bad for a quick test.

I gave the machine to Steve, he first commented on how light it was, he was very impressed with the performance and Iron rejection he gave it the thumbs up, another point he commented on was the Cibolas ability to find good targets in and around Iron, the "see through" capabilities were excellent, this machine requires a slow sweep speed for best results a little like the Lobo.
Although I was impressed with this machine I needed another opinion, because its so easy to get excited about something new and loose the reality of things. I e-mailed a friend Tony who lives up north but travels this way regularly with work,Tony is very critical about machines and puts them through some almost impossible tests, things that most of us would not even think about, he is looking for tiny Saxon coins in bad soil littered with nails obtaining 2 inches depth is considered acceptable.
I asked him to drop in next time he was down as I had something to show him and to bring a bucket of that nasty soil he keeps telling me about.Tony turned up 2 days later with his test pieces, machines and soil. We compared the Cibola against all our machines combined, several different tests,coins next to iron, gold next to nails, tiny Saxon coins buried in bad Iron contaminated soil which stained your hand black when you touched it. The Cibola was easily on par with the best available I got the seal of approval from Tony that was good enough for me.
Summing up

Yes this is a new "hot" Tesoro, no bells or whistles just raw power combined with good Iron rejection...what more can a relic hunter ask for.

Its been really hard keeping a lid on this one during testing.

My best find so far,a Silver Roman.

Marks
10/10
This is one of the tests we tried with the Cibola
Recovery speed and discrimination
Cibola test reject the nail
Reject a large nail
The Cibola found the coin next to Iron
Place a coin as close to the Iron as possible, the tesoro cibola easily located the hammered coin with a clean signal less than 1cm away from the Iron.
Impressive....I think so, even better when you think the Tesoro Cibola only costs £399.00
will your metal detector pass this test.
The badly mineralised soil test

This badly mineralised soil is laced with tiny Iron particles,
most "top of the range" metal detectors will not even find a small coin less than 2 inches deep.The Cibla was in the top 3 we tested.
