Something tells me this will be of little use to the average coin/jewelry/relic hunter, as far as deciding what signals to dig vs not dig. Call me a kill-joy, but it looks like the pixel sizes are too small to be of any use. I think some people have the impression that they are going to get a "magical" picture in 3D of various objects. Like a round tab verses a nickel vs a gold ring. Or a coin vs. a foil blob, etc.... But I highly doubt the pixel sizes and resolution are small enough to determine anything like that. All "coin sized" objects (tabs, foil blobs, coins, keys, rings, etc...) will all just be a messy blotch of pixels, not some magical shape that perfectly mimics a beaver tail off a tab, or a crucifix vs a bullet shell, etc.....
Same for the "imaging" detectors: the pixels are something like 1" across. Therefore everything in coin size is all just 1 pixel across! Doh. Even something as tell-tale as a horseshoe (that you might *think* would look, in the image, like a horse-shoe shape), is still just a confusing blotch of pixels.
And can you imagine the cocophany of blotches and screen pictures from junky sites with blurs of signals/targets?
Sorry to be a kill-joy, but I don't think the day is here where we can look into the ground and discern square tabs vs round ones vs ring, etc...
