Medium-diving crankbait
The middle-of-the-water-column shape: a hollow plastic body with the lip stacked lower and further back under the nose than a square-bill's.
What is a medium diver?
A medium-diving crankbait is a lipped bait built to swim below the surface on a retrieve. This version pairs a plastic body and belly ballast with a lip below the line tie; the Tank tests whether the lip load and righting force balance.
What the model actually measures
The grid uses 1 cm cells. The Tank computes displaced water, centre of mass, lip force, tracking stability and wobble at its default retrieve speed. It does not predict a running depth or a catch rate. See the equations and limits.
ABS shell, a two-cell lip stacked under the tie, four lead slugs along the belly, a rattle chamber amidships.
Tank verdict: Swims
Swims. A moderate wobble at fast tempo — busy and aggressive, the classic searching action.

Compare with the square-bill
Both designs run through the same Tank model at its default retrieve speed. These figures describe the block builds shown here, not commercial lures.
