Cortez in highly mineralized soil

[Cooch]

I have a Cortez which is great on Sandy beaches or clean soil. The problem is my area is very very rocky and the rocks have s lot of iron. As an example, my driveway is local crushed stone and the Cortez seems to hit on every single stone. It's the same thing in the old fields: all the stones hit no matter what setting. I can put discriminate all the way up and sensitivity to zero and the beeping is unbearable. I'm using an 8 inch round coil. Not sure if a double D would make a difference. Seriously thinking of buying a minelab and selling the Cortez . Any suggestions?

You need a machine you can manually ground balance. Get an Outlaw with the 3-coil package.

When I used to run my Cortes it definitely had manual ground balance
And yes it would hit salty rocks down the beach, but not all rocks. ( In the wet sand area's)
Ground balance is the key to getting it right, but not sure if it should be more positive or neutral.
Just have to keep moving the settings very slightly and see.

It was a really nice machine , after all Tesoro rocks!

The ground balance only affects all metal. In disc, the GB is preset. A huge drawback for a $850 detector in 2017!

Same with the Lobo Super Traq. You lose a lot of depth as soon as you flip out of All Metal. I would suggest a DD coil for it instead of the stock concentric.
