Does my replacement 9X8 coincentric coil have to be tuned to my Vaquero?

[Jay of MS]

I am having to get a replacement coil for my Vaquero. Do I need to send in my detector with this coil so they can be tuned together? The Vaquero has ground balance and I was told that because of this there is no need to send it in to be retuned but I just wanted to ask the experts. Thanks again.

No you don't need to send any Tesoro detector in to have it calibrated to a new coil that you bought as an accessory to any Tesoro detector.

Every time you set out to hunt you should ground balance again before starting detecting and then check GB every once in awhile to make sure it hasn't changed a lot for best results.

No detector with a ground balance needs to have the coil calibrated as the G.B. is doing it for you, as you have been told. With a Tesoro or any other detector without G.B. then the internal trimmer may well need adjustment but the problem with this is the stock coil and the new coil may need different settings and trimmers are not designed to be reset often. In Europe you would have a small modification done with an external switch to select each different coils optimum setting.

Far easier/cheaper to buy a model with adjustable G.B. in the first place.

These guys are correct. You're good.

This is true. On the Vaquero and Tejon you do not need to have it tuned. Only units that have a factory preset ground rejection need it. However, if you bought a used coil, it is always good to send it in to see if the coil needs to be re-tuned. Age can cause the wires inside to shift.

Wow thank you all. DOesn't the Cortez also have manuel ground balance so it too would never need to be tuned to it's coil correct?

Correct...

No, This is not true. The Cortes manual ground balance is only in the all-metal mode. The discriminate side is a factory preset ground rejection!

I see, thanks robert.

You are welcome!

so the vaq has ground balance in all metal and discrimination mode? I guess when you set GB in all metal and then click to discrimination the GB follows over?

once i ask tesoro if i have to send in the vaq. to use the 12x10 coil. they said i don't have to if i use it in all metal. i had use it in disc. with no problem. so i guess the tesoro tech know what they talking about. guess the smaller coils ok to use without calibrating the detector.
