Technium Invisitec is a clear-coloured, low-stretch sinking monofilament designed for anglers who demand strength, stealth, and precision. Engineered with an advanced triple-layer construction, it delivers extremely low stretch, significantly less than standard mono. Despite its low-stretch profile, Technium Invisitec remains impressively supple, ensuring smooth, tangle-free casting and flawless presentation.
If you’re a dedicated carp, feeder or surfcasting angler, you’ll already know that Technium Invisitec has earned a stellar reputation as one of the most advanced mono lines on the market. It’s especially effective in clear water conditions thanks to its ultra-clear finish that blends seamlessly with any lake or seabed, offering unmatched stealth. What sets Technium Invisitec apart is its clever balance between braid-like sensitivity and the forgiving nature of mono. With up to 50% less stretch than standard monofilament and a high strength-to-diameter ratio, it delivers superb casting performance and enhanced bite detection. Its low-stretch core improves responsiveness for cleaner hook sets and a more connected feel during the fight, without the harshness of zero-stretch braid. Add in its fast-sinking properties and excellent abrasion resistance, and you’ve got a line that performs brilliantly in demanding scenarios.
Whether you’re targeting big carp in crystal-clear lakes, fishing a method feeder or punching baits out at distance in the surf, Technium Invisitec gives you the edge in strength, stealth, and control - cast after cast.

Technium Invisitec is engineered with a unique three-layer construction that delivers a perfect balance of strength, sensitivity, and handling. At its core, a hyper-resistant centre layer provides low-stretch performance - reducing stretch by 50% compared to standard monofilament. This heightened sensitivity dramatically improves bite detection, while still retaining just enough give to play fish with confidence and control.
The middle layer adds a remarkable level of suppleness, instantly noticeable the moment you handle the line. This flexibility enhances casting distance and accuracy, while also contributing to its impressive knot strength and overall manageability.
On the outside, a silky-smooth outer coating protects against harmful UV rays and boosts abrasion resistance, all while reducing friction through rod guides for longer, cleaner casts. The result is a high-performance mono that combines the best qualities of low-stretch lines with user-friendly handling and superior durability.
