25 years ago in 1998 the Team at Zenaq introduced the Monster Buster, specifically designed to catch monster tuna. Since then, the passion has driven the team at Zenaq to continually develop rods for big game fishing. Advancements in tackle, including lines and hooks, have made tunas over 200kg a feasible target. Yet, The Zenaq team aspired to create a rod capable of going head-to-head with these giants in the casting game. This ambition led to the inception of Project Monster Buster.

Creating the Ultimate Monster Rod Blank
The key feature we focused on during the development of this rod was its ability to lift a 200kg fish, even when bent at a deep angle.
If the rod blank is too rigid, it becomes difficult for anglers to endure the intense struggle of fighting a monster fish. Additionally, a stiff rod blank wouldn’t allow for casting a 100g lure effectively.
On the other hand, a rod blank that’s too flexible wouldn’t be able to lift a 200kg monster and would likely snap under such heavy pressure.
So, how do we resolve these conflicting requirements? How can we design a rod that casts a 100g lure with distance while still enabling an average-sized angler to battle a 200kg monster tuna?
This was the greatest challenge of Project Monster Buster.
Our journey to create the perfect rod blank involved countless cycles of design, bench testing, and field trials, culminating in a breakthrough after four years of testing, starting in 2019.
The result? The innovative rod blank that forms the backbone of the Tobizo TC77 TUNA – Monster Buster.


What is DBL Structure (Deep Bias Layered Construction) – PAT.P
The process of creating rod blanks involves many factors, such as the elasticity of the carbon material, thickness, resin content, fiber angle, and the taper design of the mandrel (mold). With so many variables at play, the possibilities for designing rod blanks are virtually limitless.
Within this vast range of combinations, we search for the optimal material, layering it deeply and carefully arranging the fiber orientations to achieve the perfect configuration.
Our approach to designing the rod blank is fundamentally different from the lightweight, finesse-oriented rods typically seen. It’s more akin to crafting the physique of a well-trained heavyweight athlete. This manufacturing method enabled us to precisely design the torque and power necessary to meet the requirements for recoil, durability, and flexibility, which are essential for our monster rod blank.
In developing the Monster Rod, it wasn’t just advanced rod-making technology that was crucial—it was also the patience and dedication to finding the perfect combination of complex carbon materials from an infinite array of options.

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.
