Sinking rate is how fast your lure falls through the water, usually in feet per second. Once you know it, you can count your lure down to an exact depth instead of guessing, and match your jig to the depth you need to reach.
| Lure weight | Sink rate | Time to target | Typical use |

A lure falling through water reaches a steady speed where the pull of gravity is balanced by drag. Heavy, compact lures fall fast. Light, bulky lures — a weightless plastic, a big paddle tail — sink slowly because they push more water for the same weight.
The practical unit is feet per second. A jig that falls at 1 ft/s covers 12 feet in 12 seconds. That is your countdown: say "one one-thousand, two one-thousand" and you know roughly where the lure is.
Cast, let the lure hit the water, and start counting the moment it does. Let it fall for the number of seconds the calculator gives you, then begin your retrieve. Your lure is now in the strike zone from the very first turn of the handle.
The other use is staying in contact. If you know the lure falls one foot per second and you are working a 15 foot edge, you can let it fall for 12 seconds and start your retrieve without touching bottom.
Thin line cuts through water and lets a lure fall freely. Thick line drags and slows the fall. On a light jig, going from 15 lb mono to 10 lb braid can change your sink rate by a third — which is the same as switching to a heavier jig without changing lures.
This is one of the few times braid is a straightforward upgrade: thinner line for the same strength means a faster, more natural fall and better feel when the lure does touch bottom.
Sink rate only matters if you can feel the lure. These are the ones that hold a fall you can count.
The classic countdown lure. Lead head, hair tail, falls head-first at a predictable rate and works from panfish to striped bass.

A countdown only works if you know the rate behind it. The jig head weight calculator sets the weight for the depth, the trolling depth calculator covers moving presentations, and the lure color chart decides what to fish once it gets there.
Most anglers want roughly one foot per second as an all-round rate. Half a foot per second is a slow, finesse fall. Two feet per second or more is a fast fall for deep water or fish holding tight to the bottom.
Pick a known depth, cast out, let the lure hit the water and count the seconds until it touches bottom. Divide the depth by the seconds and you have feet per second.
Yes. Braid is much thinner than mono or fluorocarbon at the same strength, so it drags less through the water and your lure reaches its natural sink rate instead of being held back by the line.
Usually the line. Thick mono, a windy day bowing the line, or a bulky soft plastic all add drag. The calculator assumes a slack-line, straight-down fall.
Count down gives you a starting point, not a fact. In current the lure drifts as it falls, so it will be further downstream than directly below you. Use a slightly heavier lure to compensate.
