[QUOTE="XLOOX, post: 595387, member: 16174"] Thing with spherical weights is that it is astounding how quickly the weight increases with the "size" even though we all know it is simply going up proportional to cube of diameter. These are a bunch of fishing sinkers so all 6.5 mm & above will have a 2mm hole thru them. All below have a split. [img]https://www.prospectingaustralia.com/forum/img/member-images/16174/1612778724_lead_ball_sinker_dia_vs_weight.jpg[/img] Also the detectability is based on the surface area and conductivity of the target not the density or weight so whilst a sphere of say 30mm dia might weigh 8x the weight of a 30mm coin it would only be detected maybe 50% deeper [/QUOTE]
