While striking bottom is done by heaving the lead, it usually has only one sinker on the line, a tapered thing like a sash-weight, with a hollow cup indented on the bottom for the wax plug used to collect bottom sample. I have never seen or heard of a two-lead method, and I think this is an invention born of misunderstanding.

Sinkers, or sunkers, are submerged rocks, so named because they have a nasty habit of sunkin' yer boot when you least expect it.
