Red Monster

The oversized No.10 hook held firm, and hooked up reliably.
This is truly reassuring strength, even against a monster.

Why a High-Speed Fall?

10m, 20m, 30m deep... A rip current rages, strong wind kicks up the waves.
Under harsh conditions, you drift with the tide, the lure's orientation destabilizes, and you miss the chance.

That is why it has a 39g high-speed fall.
Reach the bottom in an instant, and tempt the monster with the ideal orientation.
That is the Daybreak 4.0.

Three Specs That Take Down the Red Monster

A 39g High-Speed Fall

Reach the bottom in an instant. The orientation stays perfectly stable even in a rip current or strong wind. Search the spot efficiently. Even at 30m deep, it reaches the bottom in just a few dozen seconds.

Tough, Heavy-Gauge Stainless KS No.10 Hook

Even a red monster over 4kg won't bend the hook. It hooks up for sure and lands the catch for sure. That is the strength of the KS No.10 hook.

Ultra-Light 2.5mm Carbon Shaft x Ideal Buoyancy Balance

Strong yet lightweight. The underwater orientation stays perfectly stable even during a high-speed fall. A meticulously calculated body design. The specific gravity and fluid characteristics are optimized through hard-foam urethane resin molding technology.

Further Weight Adjustment Is Possible

The Daybreak size 4.0 is designed so that head sinkers (TR sinkers) from various makers can be attached.

When 39g is not heavy enough, or when you attack even deeper water, you can add weight by attaching a head sinker.
A head shape that makes it easy to secure the band prevents slippage on bottom contact and during jerking.

Development Story

High Sensitivity and Power, Together!

The size 4.0 DAYBREAK® is an egi that, for the first time in a long while, gave us a real sense of response and breakthrough.

Developing the size 4.0 DAYBREAK® reminded us once again of a core truth in egi development: "the most critical factor is mastering the body's performance (specific gravity and fluid characteristics)." In early April 2024, the fifth Daybreak body prototype was completed. The functions required in development were: "(1) mount an oversized No.10 hook," "(2) achieve an ultra-high free fall speed," "(3) a superb tension-fall balance," "(4) a visually beautiful form," and "(5) ease of mass production."

Over the 25 years since our founding, we have developed countless size 4.0-size egi fitted with an oversized No.10 hook, but with this size 4.0 Daybreak, we felt a certain chemistry the moment we first checked it after the body was completed, the first such egi in a long time. After a long development period, we were ultimately able to satisfy every function this project demanded.
