Monster Buster for 200kg Tuna


Project Monster Buster

Project MB

For catching the 200kg+ monster.

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.

MONSTER BLANK Development Story
After years of trial and error, Monster Blank was finally completed.
This short movie takes you behind the scenes of its development.

Creating a True Monster Blank

The key feature we prioritized in developing this rod was its ability to lift a 200kg fish while being bent at a deep angle.
If the rod blank is overly rigid, it becomes too challenging for anglers to endure the fierce struggle of a monster.
Additionally, such a stiff rod blank wouldn't allow casting a 100g lure.
On the other hand, a rod blank that's too flexible wouldn't just fail to lift a 200kg monster but would also easily break under the heavy load.

How do we resolve these conflicting requirements?
How could we design a rod capable of casting a 100g lure far and still enable an average-sized angler to battle a 200kg monster tuna?
This was the greatest challenge of Project Monster Buster.
Our journey towards creating the perfect rod blank involved relentless cycles of design, bench testing, and field testing, and was finally completed after four seasons starting in 2019.
The result is the innovative rod blank that is the backbone of the Tobizo TC77 TUNA - Monster Buster.

What is DBL Structure (Deep Bias Layered Construction) - PAT.P

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.
  • An Incredible 40-Minute Battle
    In just 40 minutes, a lone angler managed to reel in a 213kg monster tuna.
    This remarkable achievement highlighted the exceptional performance of our monster blank, crafted for the challenging task of bending under huge pressure and lifting such massive monster tuna.



    Thanks to the DBL Structure, 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 Setting
    We'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 Seat
    The 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 End
    For 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.
