Thanks Lanny.
I do like the 705 and I am learning the number system. I just set the iron mask to 0 if I want to dig everything.
Saturday our club had an outing at a mining museum where we were allowed to detect the entire property. I had my iron mask set to 2. When I passed over an object I heard the pause through my headphones but no beep. Before I dug I changed the iron mask to 1 with the same results. Once I set it to 0, I heard the beep.
I dug up the item which was an old mule shoe which I might have missed with the factory iron mask setting.
On an old square head nail, it beeped at iron mask 1 and below. Still learning but it is a great detector.
