A shoal of mackerel is working forty metres out. You cast into the middle, let it sink for ten seconds the way you were taught, and reel in. Nothing. You go again, still nothing. Meanwhile the angler next to you is hooking fish after fish by cranking flat out the moment the jig hits the water.

The explanation is simple: when a shoal of pelagics is feeding, it is **above** your line of retrieve, not below it. Letting the jig sink takes you through the active zone in three seconds on the way down to a depth where there is nobody. On these fish, the decisive variable is neither colour nor profile: **it is speed.**

The Jack Eye is built around that idea. It is a retrieve jig, shaped to stay stable and straight at speeds where most jigs start spinning on themselves and twisting your line.

## A jig that does not spin when you speed up

This is the central problem with metal jigs retrieved fast. A body that is too flat or badly balanced starts rolling on its axis past a certain speed. The lure rises, drifts towards the surface, and your braid ends up in corkscrews.

Three design choices avoid that:

- **A fairly centred mass distribution**, which stabilises the lure along the line of pull instead of letting it tip over.
- **An elongated profile** that offers little lateral resistance to the water, so little rotational torque.
- **A slightly asymmetric section** that keeps an irregular flash without compromising the track.

The practical result: you can wind as fast as your hand allows without the jig leaving the water or going into a spin. And as soon as you stop, it tips onto its flank and flutters back down, which triggers most sea bass takes.

## What the stock assist hook brings

Hayabusa is a hook manufacturer first, and it shows in the rig it supplies. Two points matter.

**The length of the cord.** An assist hook that is too long tangles around the body on every cast; too short and it does not cover the strike zone. The usable marker: the point should reach roughly a third of the way down the jig body from the head.

**The hook wire diameter.** On mackerel, fine wire pricks on its own. On a good sea bass hooked in the swell against rocks, you need heavy wire, even at the cost of some sharpness of penetration.

Plenty of anglers keep the rear treble as well. That is a choice: more fish hooked, but also more snags, more breakages and a fish that is much harder to release cleanly. On a shoal of mackerel, take it off — you will gain more time unhooking than you lose in bites.

> On the water: if you are catching fish hooked outside the mouth, you are retrieving too fast for them. If you are catching nothing at all while the shoal is visible, you are retrieving too slowly. The proportion of fish hooked cleanly is your best speed indicator, well ahead of the number of bites.

## Choosing the weight

Unlike deep searching jigs, the criterion here is not reaching the bottom but **being able to hold the speed you want at the depth you want**.

| Situation | Weight | Speed |
|---|---|---|
| Shoal at the surface, no wind, short range | 20 to 30 g | very fast, non-stop |
| Shoal at 30-50 m, light chop | 30 to 40 g | fast, two stops per retrieve |
| Sea bass in mid-water, 5 to 15 m | 40 g | medium, with 3-second drops |
| Headwind or current, searching the bottom | 50 to 60 g | slow, saw-tooth retrieve |

A heavy jig retrieved fast still rises: weight does not force you to fish deep. What it gives you is casting distance and the ability to hold in wind.

## The retrieve: three speeds to sweep through

Until you have found the rhythm of the day, keep the same lure and vary the speed. That is more effective than changing colour.

1. **Cast and start winding immediately**, before the jig has even sunk. Fast, constant retrieve, no twitches. That is the mackerel setting.
2. **If nothing comes**, let it drop for three seconds after the cast, then retrieve fast with **two clean one-second stops** midway through. The bites come as you start again.
3. **Still nothing**: let it sink to mid-depth, then work a **saw-tooth retrieve** — two upward flicks of the rod tip, two turns of the handle, a free fall of two to three seconds. That is the sea bass setting.
4. **Watch the line during every drop.** A line that stops sinking or moves off sideways is a bite. Strike by winding fast.
5. **Note the sequence that paid off** and repeat it exactly: on a shoal, the winning rhythm often holds good for an hour.

## Where it excels, and where it has no business

The Jack Eye is made for **fast, active fish**: mackerel on a shoal, sea bass feeding under birds, fish passing a point or the end of a breakwater on the tide. It is also good from a boat, cast and retrieved over a located shoal.

It is poor in two cases. **On settled, inactive sea bass glued to the bottom in winter**: a heavily weighted soft plastic, worked slowly, will be far more productive. And **in very deep water beyond thirty metres**, where a slow vertical retrieve calls for a jig designed for it.

## Jack Eye or Jigpara

Both belong to the same family but they are not fished the same way. The [Major Craft Jigpara](https://carnafish.com/en/leurres/majorcraft-jigpara/) is a flat jig whose work is mostly done **during the fall**: it flutters, it drifts, and the bite comes on the drop, often on a slack line. It is a patient searching jig.

The Jack Eye takes the lead as soon as you want to **hold a high speed without losing the track**. Where the Jigpara starts to wander off, it stays straight. Fishing a shoal at the surface is its home ground.

If you are looking to cut through wind and drop fast to the bottom, the [Illex Dexter Jig](https://carnafish.com/en/leurres/illex-dexter-jig/) plays on density. And if you are fishing small species in a harbour with light gear, switch to the [Major Craft Jigpara Micro](https://carnafish.com/en/leurres/majorcraft-jigpara-micro/), which changes the scale of the game completely.

## Key takeaways

- On an active shoal, retrieve speed matters more than colour or weight.
- The profile is designed to stay straight at high speed, with no spinning and no line twist.
- The assist hook should reach about a third of the way down the body; the rear treble is optional and often a nuisance.
- Weight buys you distance and control in wind, not fishing depth.
- Excellent on active fish, weak on settled sea bass on the bottom or in deep water.

## FAQ

### Should I let the jig sink before retrieving?
Not when a shoal is feeding at the surface: start winding on impact. Letting it sink for ten seconds takes the lure below the active zone. Save long drops for searching out sea bass in mid-water or on the bottom.

### What retrieve speed should I use?
Start very fast and slow down gradually until you find the rhythm. A reliable indicator: if fish are hooked outside the mouth, slow down; if you get no bites at all on a visible shoal, speed up.

### What weight for fishing from the shore?
20 to 30 g with no wind at short range, 30 to 40 g to reach forty or fifty metres, and 50 to 60 g into a headwind or a strong current. Weight mainly buys distance, not depth.

### Should I keep the rear treble?
On mackerel, take it off: you will save a lot of time unhooking and avoid plenty of snags. On good sea bass near rocks, keeping it raises the proportion of fish hooked.

### Does the Jack Eye catch sea bass sitting on the bottom?
Rarely. It is a lure for active fish. On inactive bass glued to the bottom in winter, a heavily weighted soft plastic worked slowly will be clearly more productive.

### Why does my jig twist my braid?
Because the lure is rotating on its axis, generally due to a retrieve too fast for its profile or a rig without a swivel. A solid ring plus a small swivel at the head of the leader removes the problem.
