The mixed 7mm and 10mm hexagon hole pattern retains small targets like thin gold chains, worn silver coins, and small earring backs that would fall through a uniform 10mm scoop, while the larger 10mm holes in the upper basket clear heavy sand and shell debris faster than a uniform 7mm pattern. This dual sizing is critical when you're working tourist beach zones where the target mix includes both modern fine jewelry and old coins. The 7mm holes in the lower basket catch small finds, and the 10mm holes higher up speed drainage so you're not waiting for every scoop to clear before the next dig.
