Excalibur Changing it's tunes

[skateteacher]

I bought a new Excal II last week and finally got to take it out the other day. I didn't submerge it as I was working the wet sand and wading in and out of the shore break up to 1-2 feet. My threshold tone changed every so often going from the light type sound to one where it sounded like I'd stirred up a hornets nest. This occurred in the dry, wet and submerged sand. It seemed more random than anything else but I thought I would ask and see. It was a very quiet beach, no signals at all in the wet sand and I discovered a recently buried 6 pack of Modelo negro's along with the bottle caps in the dry sand. Of course they were all empty.

Most likely your coil passed over iron and the change in threshold tone indicated just that. The next good signal would switch it back till you hit iron again. I usually just swing towards my scoop and it changes back to the better tone. That's what it seems like to me anyway.

Thats normal... surfman pretty much nailed it...

Makes sense. Thank you very much.

Its called PITCH HOLD. It was used on many of the gold machines initially as a way of identifying weak signals. Changes to the last target tone.

I read a post somewhere that if the threshold went from low to a wierd high tone that you just passed over a deep target.
One day on dry sand in the winter I did find a deep crusted penny when that happened.
