Yes, always check unfilled holes then fill them in.
Never experienced finding any gold myself but a mate of mine has on two occasions. One trip I heard him bellowing in the distance and my first reaction was he may have been bitten by a snake. He came running out of the bush very excited and dropped a large lump of ironstone in my hand, it was riddled with gold. He took me back to the spot, a large unfilled hole on the side of a creek, how the previous prospector missed this is beyond belief.
On another occasion, again, another unfilled deep hole which had probably only been dug in past 24 hours, dirt was still damp. Poked his elliptical coil into the hole and got a signal, further digging and out came a 26g pure nugget. :100: :goldnugget:
The lucky b*****d has also won a second division in lotto....... Say know more!
), where I see many people not overlapping their sweep but running each sweep close to the previous one, it seems nuggets could be easily passed over at any depth (assuming the ground hasnt been flogged). Maybe people are trying to cover more ground in the time they have, but its self-defeating due to the un-scanned ground between sweeps, & anyone correct me if Im wrong, but this issue is likely to be more prevalent with big Mono's.
