Deep-diving crankbait
A long lip doing most of the work. The point of the shape is depth; the cost is a lot of lip area for the body to hold upright.
What is a deep diver?
A deep-diving crankbait uses a larger lip to pull the nose downward on the retrieve. The Tank can estimate lip force and tracking stability here, but it cannot predict an actual running depth because line angle and length are outside the model.
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.
Balsa body, a five-cell lip running down and ahead of the nose, five lead slugs along the belly, one rattle.
Tank verdict: Swims
Swims. A wide, rolling wobble at slow tempo — the slow, thumping roll that big fish track from a distance.

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