Two Ultimate Rods Built to Conquer the Impossible.
Project Monster Buster
Project MB
At ZENAQ, 25 years ago in 1998, we introduced the Monster Buster, specifically designed to catch monster tunas.
Since then, our passion has driven us to continually develop rods for big game fishing.
Advancements in tackle, including lines and hooks, have made tunas over 200kg a feasible target.
Yet, we aspired to create a rod capable of going head-to-head with these giants in casting game.
This ambition led to the inception of Project Monster Buster.

Creating the Ultimate Monster Blank
The core challenge behind Project: Monster Buster was clear:
To create a blank that can cast 100g-class lures with distance—yet still bend and lift a 200kg monster by the hands of an average-sized angler.
Too stiff, and the rod becomes a brute tool—impossible to control, exhausting to fight with, and incapable of casting lightweight lures with any precision.
Too soft, and it won’t survive the battle. It won’t lift the fish. It will simply break.
How do you overcome this contradiction?
The answer: relentless refinement.
Over the course of four years—through countless cycles of blank design, bench testing, and brutal field testing—we pushed every limit to create something that had never existed before.
And in the end, we did.
The result is the revolutionary Monster Blank—the backbone of the Tobizo - MONSTER BUSTER series.

What is DBL Power Booster
The process of making rod blanks involves various factors such as the carbon material's elasticity, thickness, amount of resin, fiber angle, and taper design of the mandrel (mold). The possibilities for making rod blanks are endless.
Among this infinite array of combinations, we search for the optimal material and layer it deeply, finding the perfect orientation of fibers, and stacking them.
Our chosen method of designing the rod blank is a world apart from rods designed for finesse and lightness. It's akin to crafting the physique of a well-trained heavyweight athlete.
This manufacturing process allowed us to precisely design the necessary torque and power, fulfilling the requirements for recoil, durability, and flexibility needed for our monster blank.
In developing the Monster Rod, not only was high-level rod making technology crucial, but also the patience to find the optimal combination among an infinite array of complex carbon materials.

A whole new kind of monster rod built to land 200kg giants with lightweight lures.
Tobizo TC80 TUNA - MONSTER BUSTER - DBL
Length: 8’0” / Lure Max 60~160g / Lure Best 70~140g / PE 8~12
As its name suggests, the Monster Buster was made to dominate 200kg-class tuna—with incredible lift power.
But its true strength lies in its ability to cast and control lightweight lures with remarkable ease.
Traditional tuna rods could hardly handle 70g-class lures with accuracy and distance—but this one can.
A power rod that breaks the trade-off—delivering both massive strength and uncompromised performance with lightweight lures.
By expanding the lower end of its lure range, the rod allows for more flexible approaches—dramatically increasing hit probability.
It also supports large plastic lure styles commonly used in European bluefin tuna games.
And when the fight begins, the Monster Blank, driven by the DBL Power Booster, delivers explosive recoil as it bends—producing astonishing lift power.
A fusion of “lightweight lure operability” and “uncompromising power”—only possible through DBL technology.
This is a new weapon to overcome once-impossible conditions—and finally land your dream.

A flagship monster rod born to conquer 200kg-class tuna.
Tobizo TC77 TUNA - MONSTER BUSTER - DBL
Length: 7’7” / Lure Max 80~230g / Lure Best 100~180g / PE No Limit
This rod was built for one purpose—turning your dream of landing 200kg giants into reality.
ZENAQ’s ultimate tuna rod, designed to support the angler through every second of the fight.
With its high-repulsive Monster Blank, it enables anglers of all body types to fully bend the rod and apply relentless lift—even against monstrous 200kg tuna.
Its taper design blends raw power with refined flexibility, allowing explosive force without sacrificing control.
What’s more, it withstands full-drag pressure from large reels at 65°rod angles—delivering unrivaled durability in extreme battle conditions.
But this rod isn’t just about brute force.
Its action is tuned for smooth use of heavyweight lures over 150g—allowing you to cast long in bait ball situations and animate large lures with lifelike motion.
Engineered with the groundbreaking DBL Power Booster structure, this is a monster rod that breaks every convention.
And it’s matched with only the toughest components worthy of facing off against true giants.

MONSTER BLANKThanks to the DBL Power Booster, this rod blank boasts impressive heavy load durability, able to withstand the maximum drag from a large reel even at a steep angle of 65 degrees. Its core flexibility allows the rod to be bent effectively with realistic human strength, generating repulsive power as it bends. Even in a fight with monster tunas, the rod blank remains robust, assisting anglers by lifting while enduring the strain.
Its length of 7’7’’ optimizes casting performance, lure control, and performance when facing the heaviest fight.
This flexible rod blank can elegantly handle lightweight lures, accurately casting them to the desired spot.
It offers a significant advantage in tuna casting game.
To take on monster tunas that exceed human limits, the rod blank must be absolutely trustworthy. -
Guide SettingWe've configured our guides for use with ultra-large tackle such as reels over size 20000 and PE lines with a PE rating of 12.
Moreover, the Assist Guide significantly reduces line tangling at the tip, eliminating line troubles and enabling smooth line release and stable long-distance casting.
This ensures you don't miss the big chance. -
Hexagon Rubber Grip (PAT.P)For big game reliability, we've developed an entirely new heavy-fighting grip incorporating rubber material in our trusted Hexagon Grip. (PAT.P)
It performs the greatest slip resistance ever.
The molded surface pattern of Japanese-style tortoiseshell enhances grip strength and minimizes fatigue in a big fight.
This ultimate grip from ZENAQ is indispensable for prolonged power fights against monster tunas. -
Metal Reel SeatThe amount of stress put on the reel seat when going head-to-head with a monster catch exceeding 200kg is enormous.
This robust metal reel seat is designed with the utmost priority on absolute capture, allowing you to concentrate all your nerves on the fight.
Moreover, the rubber cushion sheet improves the fixation of the reel.
It reduces angler's stress in fighting and repeated casting.
*It may peel off after repeated use, but even if it peels off, there is no problem in use. -
Metal Gimbal + Rubber EndFor the rod grip end, we've adopted a combination of a metal gimbal and a rubber end.
If facing a monster without a gimbal is your style, use the rubber end.
Remove the rubber end to use for the gimbal fight.
Our design provides two grip ends for the best fighting style.
If moisture permeates between the metal gimbal and rubber end in the rain, the rubber cend may easily come off, so please be especially careful when casting.
Use our Reel Stop Rubber or tape to prevent water from seeping in between the rubber end and the metal gimbal to prevent it from coming off.
