Suspending Jerkbait (SP)

Q: Why does my jerkbait sink (or float up) on the pause when the package says "suspending"?

Because it is tuned neutral at one water temperature — for most makers about 13 °C (55 °F), between 10 and 16 °C (50-60 °F) depending on the brand. The plastic body shrinks and swells with temperature more than water changes density, so colder water makes the same bait sink slowly and warmer water makes it rise. Add SuspenDots (lead tape) on the belly in warm water, remove them or fit lighter trebles in cold water; one 0.2 g dot moves the neutral point by roughly 5 °C (9 °F). Check it in a bucket at lake temperature.

Q: How long should I pause?

Water temperature sets it: 10-30 s below 10 °C (50 °F), 5-15 s at 10-13 °C (50-55 °F), 2-5 s at 13-18 °C (55-65 °F), 0-2 s above that. Post-front high pressure adds time; a chop and clouds take time away. When you cannot stand it any longer, wait five more seconds — the cold-water bite comes on the bait that sat still.

Q: Extra-fast or moderate action — which rod is right?

It depends on four things, not on taste. Extra-fast when you twitch-pause or rip on fluorocarbon with a 100-115 mm bait: the snap is crisp, slack recovers instantly and you feel the slow "weight" bite. Moderate-fast when you slow-twitch, fish braid main line, throw micro baits with 10- 12 trebles, or target smallmouth that jump — a tip with give keeps small trebles pinned. Most pros throw extra-fast because most pros throw standard baits on fluoro; that is not a rule for a 50 mm bait on braid.

Q: How long a rod?

6'6"-6'10" (1.98-2.08 m) for most jerkbait work: you twitch with the tip pointed down at the water and a longer rod hits the surface or the deck. Go 7'-7'3" (2.13-2.21 m) only for magnum baits, long casts on flats, wind, or if you are tall and fish from a high deck.

Q: Fluorocarbon or PE braid — and is nylon ever right?

Fluorocarbon 8-12 lb is the default: it sinks, so it helps the bait hold depth and suspend, and it has little stretch at fishing loads. PE 0.6-0.8 with a 1.5-2 m fluoro leader for micro baits on spinning gear and for casting into wind — with a moderate-fast tip, or the trebles tear out. Nylon is a rubber band: its 20-30 % stretch swallows the slow "weight" bite on the pause, and it floats the bait up. Not for jerkbaits; if you want a shallow runner to stay up, go to a lighter soft fluoro or the floating model of the bait.

Q: Rattling or silent?

Silent models exist for clear, open water and pressured fish — when the fish can see the bait, sound only warns them. Rattles earn their place in stained water, chop, low light, over grass and on fresh, unpressured fish. If you carry one of each, start silent in clear calm water and rattling everywhere else.

Q: One-piece or jointed?

One-piece for twitch-pause and rip, cold water, clear water, pressured fish and micro sizes — it darts clean and suspends truest. Jointed (two or more segments) for slow twitch, straight retrieves, warm active fish, stained water and the 130 mm+ big-fish sizes — the joints turn tiny pulls into body roll and add a segment click. A jointed body folds and fouls its hooks on a hard rip.

Q: What is "slow twitch" and when do I use it?

Continuous, tiny rod-tip pulls with no real pause — the bait never stops, it rocks and shakes its head side to side a few centimetres at a time. Use it on calm clear water, after a cold front, on pressured fish, over grass (where a rip buries the hooks) and with micro baits. It needs a moderate-fast tip that flexes on a 2-3 cm pull, a slow reel (6.2-6.8:1 or a 2500 spinning) and a loop knot — a Palomar tied tight kills the head shake.

Q: Can I fish a jerkbait in grass at all?

Over grass, yes; in it, no. Pick a model that runs just above the tops (a shallow runner or floater), slow-twitch or soft twitch-pause — never rip — and when it loads, ease it free and let it float up. Standard-wire trebles, never light wire: a fish that turns into the weeds opens a fine hook, and jerkbaits are not sold with heavy-wire trebles, so standard is the ceiling.

Q: Do I need a loop knot?

A loop knot (non-slip loop or Rapala) or a small snap gives the bait a free hinge so it hunts side to side on the twitch. A Palomar tied straight to the eye stiffens the action a little — fine for a hard rip, wrong for slow twitch. Snaps also let you change colours in seconds; use the smallest that fits.

Neutrally buoyant minnow bait (70–130 mm) that hangs weightlessly at eye level on the pause—the #1 cold-to-mild water and clear-lake hard bait in Canada.

Suspend, twitch, jump the slack, pause: the #1 cold-water and clear-water hard bait system across Canada, divided into Suspending (SP), Floating (F/SF), Sinking (SS/S), Deep-Diving (+1/+2/DD), Flat-Side, and Soft Jerkbaits.

Tune SP buoyancy for water temperature: add 0.2–0.5 g SuspenDots or heavier hooks above 18 °C; swap to fine-wire trebles or remove the nose ring below 8 °C.
Keep the nose split ring with a tight knot, or tie a Non-Slip Loop Knot if the ring is removed.
Throw 15–25 cm of slack back after each snap ("Jump the Slack") so the bait whips 180° to face trailing fish.

A Suspending Jerkbait (SP) is weighted with internal tungsten or brass bearings so its specific gravity matches freshwater at 10–15 °C (50–59 °F). When you crank it down to 1.2–2.0 m (4–6.5 ft) and snap the slack line downward, the bait darts erratically and then freezes dead-still in mid-water when you pause—denying trailing smallmouth, largemouth, and walleye the chance to let the meal swim away, while refusing to rise or sink out of their strike window.

1. Water-Temperature Buoyancy Tuning (Summer Weighting vs. Winter Lightening) — Because water density and the lure's internal air chamber expand and contract with temperature, a factory SP jerkbait only suspends neutrally within its 10–15 °C (50–59…

FAQ

Why does my jerkbait sink (or float up) on the pause when the package says "suspending"?

Because it is tuned neutral at one water temperature — for most makers about 13 °C (55 °F), between 10 and 16 °C (50-60 °F) depending on the brand. The plastic body shrinks and swells with temperature more than water changes density, so colder water makes the same bait sink slowly and warmer water makes it rise. Add SuspenDots (lead tape) on the belly in warm water, remove them or fit lighter trebles in cold water; one 0.2 g dot moves the neutral point by roughly 5 °C (9 °F). Check it in a bucket at lake temperature.

How long should I pause?

Water temperature sets it: 10-30 s below 10 °C (50 °F), 5-15 s at 10-13 °C (50-55 °F), 2-5 s at 13-18 °C (55-65 °F), 0-2 s above that. Post-front high pressure adds time; a chop and clouds take time away. When you cannot stand it any longer, wait five more seconds — the cold-water bite comes on the bait that sat still.

Extra-fast or moderate action — which rod is right?

It depends on four things, not on taste. Extra-fast when you twitch-pause or rip on fluorocarbon with a 100-115 mm bait: the snap is crisp, slack recovers instantly and you feel the slow "weight" bite. Moderate-fast when you slow-twitch, fish braid main line, throw micro baits with #10-#12 trebles, or target smallmouth that jump — a tip with give keeps small trebles pinned. Most pros throw extra-fast because most pros throw standard baits on fluoro; that is not a rule for a 50 mm bait on braid.

How long a rod?

6'6"-6'10" (1.98-2.08 m) for most jerkbait work: you twitch with the tip pointed down at the water and a longer rod hits the surface or the deck. Go 7'-7'3" (2.13-2.21 m) only for magnum baits, long casts on flats, wind, or if you are tall and fish from a high deck.

Fluorocarbon or PE braid — and is nylon ever right?

Fluorocarbon 8-12 lb is the default: it sinks, so it helps the bait hold depth and suspend, and it has little stretch at fishing loads. PE 0.6-0.8 with a 1.5-2 m fluoro leader for micro baits on spinning gear and for casting into wind — with a moderate-fast tip, or the trebles tear out. Nylon is a rubber band: its 20-30 % stretch swallows the slow "weight" bite on the pause, and it floats the bait up. Not for jerkbaits; if you want a shallow runner to stay up, go to a lighter soft fluoro or the floating model of the bait.

Rattling or silent?

Silent models exist for clear, open water and pressured fish — when the fish can see the bait, sound only warns them. Rattles earn their place in stained water, chop, low light, over grass and on fresh, unpressured fish. If you carry one of each, start silent in clear calm water and rattling everywhere else.

One-piece or jointed?

One-piece for twitch-pause and rip, cold water, clear water, pressured fish and micro sizes — it darts clean and suspends truest. Jointed (two or more segments) for slow twitch, straight retrieves, warm active fish, stained water and the 130 mm+ big-fish sizes — the joints turn tiny pulls into body roll and add a segment click. A jointed body folds and fouls its hooks on a hard rip.

What is "slow twitch" and when do I use it?

Continuous, tiny rod-tip pulls with no real pause — the bait never stops, it rocks and shakes its head side to side a few centimetres at a time. Use it on calm clear water, after a cold front, on pressured fish, over grass (where a rip buries the hooks) and with micro baits. It needs a moderate-fast tip that flexes on a 2-3 cm pull, a slow reel (6.2-6.8:1 or a 2500 spinning) and a loop knot — a Palomar tied tight kills the head shake.

Can I fish a jerkbait in grass at all?

Over grass, yes; in it, no. Pick a model that runs just above the tops (a shallow runner or floater), slow-twitch or soft twitch-pause — never rip — and when it loads, ease it free and let it float up. Standard-wire trebles, never light wire: a fish that turns into the weeds opens a fine hook, and jerkbaits are not sold with heavy-wire trebles, so standard is the ceiling.

Do I need a loop knot?

A loop knot (non-slip loop or Rapala) or a small snap gives the bait a free hinge so it hunts side to side on the twitch. A Palomar tied straight to the eye stiffens the action a little — fine for a hard rip, wrong for slow twitch. Snaps also let you change colours in seconds; use the smallest that fits.

What size for smallmouth versus largemouth?

Smallmouth: 75-90 mm (3-3.5 in) as the standard, and 50-65 mm (2-2.5 in) micros on rivers where they eat small minnows — on light spinning gear. Largemouth: 100-130 mm (4-5 in), longer pauses. Both eat a 110 mm; neither eats a 130 mm every day.

When is the water too warm for a jerkbait?

Roughly above 20-24 °C (68-75 °F) the suspending game fades: fish want a bait that keeps moving, and the bait itself rises on the pause. Switch to a floating shallow runner worked fast, a topwater, or a soft jerkbait. Below 4 °C (40 °F) it still works — with 20-30 s pauses.

Which reel speed?

7.1:1 baseline. 7.5-8.1:1 when you rip or burn — each rip throws slack and the fast reel picks it up before the next one. 6.2-6.8:1, or a 2500 spinning reel, for slow twitch and micro baits, where a fast reel makes the pulls too long.

How do I get it deeper?

Model first (a deep diver reaches 2.5-3.5 m / 8-12 ft), then thinner line (8-10 lb runs deeper than 12), a longer cast, the rod tip in the water on the pull-down, and a slow-sinking tune (one or two dots) counted down before you start twitching.

I get bit but keep losing them — why?

Trebles need a sweep, not a bass hookset: reel until the rod loads and lean into it. Keep the rod low and keep reeling on the jump. Check the trebles — a bent light-wire point or a dull one from rock loses fish all day. And on braid, a locked-up extra-fast tip tears holes; go to a moderate-fast tip or a fluoro leader.

Colour — natural or bright?

Let the cadence and the water decide. Slow twitch and long pauses give the fish a long look: translucent, natural, matte. Rip and burn are flash triggers: chrome, holographic, pearl. Stained water wants a chartreuse back or gold side; overcast wants solid high-contrast (black back, purple); bright sun and clear water want ghost and natural shiner.
