do you guys have a problem detecting over vintage Red brick

[Tajue17]

I am a formal tesoro user but because of the snowy weather and cold I figured I'd bring the wifes machine but I'm a memeber of "find my stuff" and tried finding a gold earing for a student of Harvard University in Cambridge, Ma. this morning, the side walks here are all red brick and really sunken down from years of traffic, they have about 3/8 gaps in between them where we think the earing fell the snow covering was about 1/2 to 3/4 and the temp was 26 degrees. since I turned it on I couldn't get my wifes machine to shut up even with the sens turned all the way down it was imposssible to find this earing..... I post this here because I am more familiar with my vaquero and want to try that but I'm not familiar detecting over red brick thats as old as who knows actually this moring was my first time..

I need your advice here, i have a compadre thats adjusted inside to run a tad hot and my vaq that I know enough about but only have the stock coil.

thanks everyone,, T in Mass

Hey T in Mass I found the following info on the web, "The properties and quality of bricks depend on the type of clay used. The most common form of clay used for everyday bricks, is that with a sandy consistency, silicate or alumina, which usually contains small quantities of lime or iron oxide." If that was the issue you had looking for the earring...........? That being said I have had issues with bits of red brick in old "dump sites" with a detector other than my Tesoro, which I have not had a chance to detect that area with as of yet. Once the weather breaks around here in Northern Illinois I will hit that area again with my Compadre and see what happens.

Jazz thanks buddy, I posted this on other forums as well and they all pretty much said the same thing as you. I leanred enough today to avoid red brick,,,,, I was thinking about it too all the goodies that are in between bricks under the sidewalks next to Harvard Univeristy.

I wonder if a smaller coil would work around it? Probably have to turn down the sensitivity, etc. Might be worth a try.......Maybe a person could just use their pinpointer in the areas between the bricks? Just a thought.

What is a 'formal' Tesoro user? Do you were a suit and tie when you swing your Tesoro's? Yes, I had the same problems with bricks; some red, some gray. Power balancing made it worse for my Vaquero.

 

[Tajue17]

formal I meant its my primary machine, I did post this question in a couple other brand specific forums so if someone noticed I was jumping around my purpose was to see if my Tesoro had an advantage here with the other machine failed.

Another possibility nobody may have mentioned: Maybe it's not so much the brick itself, but what's *under* the brick. In old areas, sidewalks and such were often built over not virgin black dirt, but a thick layer of nasty fill, most especially cinders from furnaces (they're often called "clinkers") which tend to make detectors (especially those without manual ground balance) spaz out.

A smaller double d or widescan coil should handle these conditions a lot better than a concentric coil! Red brick has a lot of mineralization in them and if there all of the brick are the same type ground balance over the brick not the dirt.

I would bet ScottBuckner is right about cinders under the bricks. I'd ground balance the Vaquero normally as described in the manual. That will put it just slightly positive in disc mode. Hunt low and slow. You'll get a lot of false signals from the clinkers, but look for a good, repeatable signal while X-ing over it from a few different directions. Cinders/clinker/bricks are very difficult to detect over, but not impossible. If you do have a smaller coil for the Vaquero, it would help. Good luck.

Maybe you should try a 5'75 DD coil if there is not much iron and SEF 10x12'' if there too.
