Michigan Badger, thank you for providing links to your test videos. I found them quite interesting. Were the quarters in the bag clad or silver? That might make a difference. Also, the soil conditions will affect the effective depth of any detector - IOW, air tests are only so good, for practical purposes. Still, I like that you took the time to create these videos and show just how important fine tuning can be. Thank you!

Glad you liked the video but I didn't do it. I found these on YouTube and thought they might be of interest here.

The young man doing these videos is doing a great job and I wrote and told him so.

Air tests are very important in one sense; they show the detectors extreme depth potential. That is, no detector can go deeper into the soil than it's air test. This is a scientific fact even if some manufactures claim otherwise.

Here's a quote from:
http://www.garysdetecting.co.uk/hoard_test.htm

"This myth is Busted
I asked Georgi Can machines that that don't air test well go deeper in the soil.
He said No absolute Crap!! this is scientifically impossible if a machine air tests badly it will detect badly in the soil despite what you read on metal detecting forums and some manufacturers literature.
However some machines that air test better can loose a higher percentage of depth in the soil around 30% depending on what type of search coil is used.
If you suspect these results are wrong, please go out there and do the buried coins test for yourself, I think you will be amazed!!!!.

As for the sixpence at 10" test we will be posting the results soon, but be warned there not good."

Air tests are of value and give a general idea of depth. Under the best circumstances one can expect at least a 30% loss of air distance as compared to ground depth.

Re: VIDEO: How Deep Is The Tesoro Cibola?

Thanks for the vids badger but I do have a concern...

Isn't it completely irrelevant to air test a coin in an attempt to determine how "deep" a detector will detect? After all even a Mickey Mouse detector will air test pretty decently but it's how a detector punches through the grounds mineralization etc that determines what it can really do. I find air tests to be a waste of time to be honest since there is no ground matrix to test the real capabilities of the machine. Just my 2 cents.

You're right. A detector that scores high in an air test may be very bad in the ground. In my quote above (by the inventor of the Nexus detector) he also states that good air distance doesn't always mean good depth.

The thing an air test does do is let us know the greatest potential of a detector. If a machine gets a max of 10 inches air test you know it can't get more than 10 inches in the ground.

Some people think they're getting more in ground depth than they're getting air distance and this isn't possible.

But again, only an in-the-ground test tells the whole story.

Yes, the young man who did this air test also did the Minelab Excalibur. I have a link to it also under this heading.

What about the fact that some coins when in the ground for long periods of time will create a soil area that is very disernable to the detector...I know they cant ground test farther in soil than in air, but this does tend to make them appear as a bigger target...I have dug a couple coins deeper, than they would air test..Not often, but it has happened over the years...Thanks, Tom

Re: VIDEO: How Deep Is The Tesoro Cibola?

Tom I do think sometimes we get nearly air test depth due to ground and target conditions. My Minelab Excalibur 1000 could barely detect a silver quarter at 7 inches in the air but once I did dig one at 7 inches depth. In most areas I got a weak signal on a quarter at 4 inches (land hunting).

Ground and target conditions do mean something.

Re: VIDEO: How Deep Is The Tesoro Cibola?

My two cents---I noticed in the air test video that he did not have the sensitivity turned all the way up therefor he was not in supertune mode. He appeared to turn it up but I have a cibola and could see that he was turning it up to just past ten and not maxing it out.
Weather he did this to discredit the Cibola I don't know. My Cibola will airtest a quarter at 13 inches with sesitivity and threshold maxed out which is how I hunt. Now the bad news--It will only find a buried quarter at 6 inches in mild Northern Illinois soil. 5 inches is the best it will do on a dime. I have buried coins at measured depths in various locations to verify these findings. I sent it back to Cibola and they returned it saying nothing was wrong with it. My conclusion----The Cibola is a lightweight machine that is easy to use and I can swing all day with no fatigue. I like the simplicity of operation and the learning curve is not that long. But [and a big but] it is not a deeeeep machine. It is 1/2 inch deeper than my BH Discovery 3300 on a freshly buried coin. All the best, Merf

Nice honest comment Merf. I think far too many just guess at the depth they're really getting.

The fact is, I've owned few detectors that could consistantly find dime sized coins deeper than 5 inches. Most detectors today are good for about 4-5 inches on a dime (a signal you would notice) in mild soil. Usually higher price means better target identification.

If I use a wooden dowel to drive a dime down 8 inches I'll still get a good solid beep from my Tejon. I believe the Tejon will detect a dme consistantly at 8-9 inches deep. The thing that brings about this extra depth is manual ground balance. Too bad the Cibola ground ajust is factory set.

Hi Badger,

I do a lot of fresh water wading and have found many coins/items deeper than they will air test using numerous machines. Wet low mineral quartz sand gives very good depth with a VLF detector, up to 50% greater than air tests.

Re: VIDEO: How Deep Is The Tesoro Cibola?

Adjustable ground balance would be a plus but my Cibola seems to be right for this mild Illinois soil. When I push the pinpoint button and bob it up and down ,as shown in the Vaquero instruction video, the tone does not change. It seems to be perfectly balanced.
Yesterday I checked out an old Raiolroad road bed and the GB was way off. When I bobbed it the tone was all over the place. I have to believe that the Vaquero with adjustable GB would not do any better as far as depth goes in this soil.
The Tejon must have more advanced circuitry and therefor is a deeper machine.
If it was the same "hot" circuit as the V and C I think it would use the same 9 volt battery.
There has to be a reason for that added battery power.
I think a Tejon will be my next detector. Best luck.

Thats just it, the Cibola does not have AUTO ground balance, it has FIXED ground balance. That is, the factory tuned it for ideal depth in conditions you are most likely to encounter and locked the balance at that spot, it won't adjust to soil conditions. The Vaquero, having manual ground balance, allows you to compensate for that and tune it to the soil.

Well I've noticed that when I encounter coins floating in air I can detect them much farther away with my Mk II Eyeballs than any of the detectors I have used. I'm pretty sure I could spot a quarter at 50 ft if the lighting was good.

I don't put much faith in air tests. At least set the object on the ground so you can see how he unit reacts with a "test" ground matrix in the coil's field. If it can't figure out a surface coin it probably won't do much better as it gets deeper. Whether there is a phenomon called "halo" that helps is beyond me. I'm neutral on that theory until demonstrated scientifically in repeatable tests.

Re: VIDEO: How Deep Is The Tesoro Cibola?

I got the Cibola back from Tesoro today and it will now find a buried dime at 7 inches and a buried quarter at 8 inches. The tune up gave me 2 more inches of depth.
The GB is still a little positive but not as bad as it was.
I sent it in 2 weeks ago to the day. Can't beat the quick service and the lifetime warranty. I hope to try it on a hunt next week.
Best luck , Merf

I went over my yard after I received my Vaquero a couple of weeks ago and found 6 wheat pennies and a buffalo nickle that my Cibola had left behind. I had both machines set just below nickles and I also dug two deep shotgun shells. I am sold on the manual ground balance. Both are fantastic machines. I thought the Cibola had got about every thing but like they say no place is ever completely hunted out. HH
