A Little Secret About Frequency Shift on The Tesoro Vaquero/Cibola

Try this:

• Ground balance your machine (Tesoro Vaquero) by being on the middle frequency (14.5 kHz)

• Now, if you switch to the lower frequency and check your ground balance, you may notice it slightly negative

• Switch now to the higher frequency, and you will notice the ground balance slightly positive

What's the utility of this??? well, imagine you are detecting a field and you find a spot with some hot-rocks or bricks..., by switching to the higher frequency you will get a more stable machine without the need of adjusting the ground balance. The difference on ground balance is not a lot, but sometimes it is just the necessary in several cases.

You may also try this with the Cibola in order to minimize some chatter caused by minerals.

Tell me if it worked for you too.

Good luck and happy hunting!

Mod: Increasing Sensitivity/Gain on the Tesoro Compadre

Find the sensitivity pot by taking the image bellow as reference, then make the necessary adjustments with a precision screwdriver. Be gentle!

Counter clockwise: more gain

Clockwise: less gain

By being away of any metallic object or any source of electromagnetic interference, increase the Gain to the point where it starts to chatter and then reduce Gain a little. Bear in mind that an stable machine is more productive and enjoyable to use than a chatter box.

Happy hunting!
