Shimano's “JET BOOST” features a revolutionary center of gravity shifting mechanism that ensures stable long casts and quick starts for the lure. This innovative technology empowers anglers to achieve impressive casting distances and catch fish effectively, regardless of their skill level.
The delay in the weight's return slows down the lure's swimming initiation.
Many plugs are designed with a center of gravity shifting mechanism to enhance casting distance. During casting, the weight shifts to the rear of the lure, enabling longer casts. As you retrieve, the weight moves back to the front, allowing the lure to swim naturally.
However, when the lure hits the water with the weight positioned at the rear, it can’t start moving immediately, even if you begin retrieving right away. Minnows and other lures with lips (protrusions that cut through the water) naturally lower their heads and shift their weights forward upon retrieval to initiate swimming; however, this action is slightly delayed.
Sinking pencils, squid jigs, and other lures without lips, as well as those with heavy moving weights, can exhibit unnatural swimming action when their posture shifts since the weights do not return to the front. This can limit the effectiveness of long casting distances and may alert fish, reducing your chances of a successful catch.

Achieving Stable Casting Distance: The Importance of Weight Shifting During Flight
Shimano engineered JET BOOST by meticulously analyzing three critical elements: initial casting speed, stable flight posture and direction, and seamless swimming initiation upon entering the water.
The internal weight that adjusts the center of gravity is securely anchored by a through shaft and spring mechanism. During casting, the weight shifts backward to enhance initial speed, and as the lure travels through the air, the internal spring automatically returns the weight to the front, ensuring optimal performance.
This movement, paired with a design that reduces air resistance, enables the lure to achieve greater distances while maintaining a stable posture.
Instantly Comes to Life Upon Water Impact
JET BOOST harnesses the spring's power to swiftly reposition the weight, allowing the lure to attract fish with a lifelike movement the moment it hits the water.
Lures such as minnow plugs and sinking pencils glide effortlessly right from the moment they enter the water, while squid jigs descend in their natural posture. With each initial wind and jerk, these lures perform their intended actions flawlessly, even after long casts, significantly increasing the chances of a good catch.
During retrieval, the spring securely holds the weight in position, stabilising the lure's motion and minimising any unnecessary noise. This design enables the lure to effectively attract fish while keeping them undisturbed.

Combining long-distance casts and smooth swimming starts enables you catch fish effectively.
JET BOOST is an innovative technology that integrates a center of gravity shifting mechanism, delivering exceptional long-distance casting performance while ensuring a stable flight posture and an immediate start to movement.
This technology enables precise long casts and a lifelike motion that immediately draws in fish as soon as the lure touches the water. It maximizes your casting distance, enhancing your chances of landing more fish.

A shimmering mirror plate that attracts fish with its irresistible shine!
When lure fishing, short pauses between actions, like jerks or twitches, can often attract fish and entice strikes.
Introducing "FLASH BOOST," designed to leverage those critical short pauses to attract more fish. A reflective plate, suspended inside the lure by a spring, continues to reflect light even when the lure is motionless, drawing fish in effortlessly.
Folded design allows targeting of new fish.
Shimano's innovative technology, ARMABOOST, significantly enhances the casting distance and accuracy of larger baits that were once thought to have limited range.
The lure folds mid-air like an armadillo, significantly enhancing casting distance and providing precision control. With ARMABOOST, anglers can cast larger baits farther with accuracy, allowing for the recreation of natural fish movements in the water.
A powerful hologram that commands the feeding instincts of fish.
Discover Shimano’s innovative “SCALE BOOST,” which gives your lure a lifelike shine that attracts even the most cautious fish. By combining hundreds of scales with varying sizes, brightness, angles, and reflections, it creates an irresistible lure that no fish can resist.
Our goal, effortless reeling.
Shimano's reel design concept aims for “eternally smooth reeling.” The result is HAGANE. Shimano honed its proprietary metal processing technologies with precision cold-forging technology and refined them over many years to develop reels that only Shimano could deliver.
