PROFIND 35 Discriminating Iron

[vladorado]

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.

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.
