Here's a small copper coin at 6" with a small nail at 3" above it just off center.
I'm in full tones for the first part, then i change to pitch. Towards the end you'll see me hitting the coin hard in pitch, then change back to full tones and sweep at the same angle, and you can see the difference.
In full tones the small nail drags down the tone of the coin so low i struggle to tell the difference between it and iron, also i think the pitch hits the coin from different angles better than full tones, you would have to come at the coin from the perfect angle to hit it in full tones.
I find the difference like night and day when hunting, and here in the UK many of the coins are tiny thin low conductors, so any advantage i can gain i take
I love the Deus in full tones, but i'd be walking past good targets using it on some of my sites, i also use 2 and 3 tones when i hit a bit of trash or coke infestation.
