PROFIND 35 Discriminating Iron

Post by vladorado » Sun Jan 14, 2018 6:17 pm

This is a short movie showing a dubious deep signal that sound like a false non-ferrous signal with the CTX3030 on all metal and combined tones. The pro-find 35 initially could not discriminate the object but when it came within 1 cm, it gave the intermittent ferrous tone.
The object was an old square nail at depth of 8 inches. These very often give false non-ferrous signals which are detected typically away from the pinpointed object.
I also demonstrated the constant non-ferrous tone the pro-find 35 gives using my brass towel clip.



Minelab CTX 3030 with 6", 11" and 17" coils.
Minelab Equinox 800 with 6", 11" coils.
Minelab Pro-find 35, Garrett Pro Pointer AT, Nokta Waterproof Pointer.
ALL THE GEAR, NO IDEA!

The question is are we going to trust it enough to always leave the target if it has got the ferrous tone? i think not myself.

It seems quite reliable in distinguishing between the two, but the pointer needs to be almost touching the target before it'll register as non-ferrous, so you might as well have a look anyway. I wrongly assumed before purchasing, that it would register as ferrous/non-ferrous from further away.
