Want to fish longer?

Svivlo Genesis ONE is the world’s first fishing reel with built-in CastGuard™ technology enabling you to Fish Longer™


The distance you need with smooth, controlled action resulting in zero risk for backlash and overrun. Just like fishing is supposed to be.


Adjustment Free


Free Spool




New experience

CastGuard™ is the only solution able to reduce spool speed by braking when the lure stops pulling the line.

This is not some new marketing bullsh*t

You’ve probably been promised a reel that is backlash free using technologies with very exciting names. But here’s the thing, as long as the only technology used is 100% dependent on speed activated brakes, they will brake more the longer you want to cast. To be fair, a few works pretty good and are well engineered, but most are not.

CastGuard™ is a deceleration activated brake able to reduce spool speed based on size of deceleration in combination with size of speed. It is by far the smartest mechanical spool control solution ever invented.

Why backlash?

Backlash is caused by several factors but simply because the spool continues to feed out line even after the lure has stopped pulling the line. This is mainly due to spool mass and rotational speed in combination with lure weight and shape. Higher rotational speed and lower lure weight with an irregular shape results in more backlash. This means that the more distance you need the more backlash you get.

What is done to solve the problem?

There are currently no properly working solution on the market. To reduce the problem there are many efforts to use centrifugal and magnetic brakes, reducing spool mass and reduce level wind friction. The problem is that these solutions combined are counterproductive. The brakes reduce cast distance while reduced friction increases spool rotational speed which in turn produce more backlash. As a result you are also forced to use your thumb which in itself has a steep learning curve with time taken away from actual fishing. 

Is the problem solvable?

To really fix this problem you need a completely new technology based on new principles. This technology should only reduce the spool rotational speed when the lure stops pulling the line independent of spool speed. but this already exists you might think. No, it is a Swedish watchmaker with incredible good sense of mechanics who managed to invent a genius technology that solved the “unsolvable” problem and takes baitcasting to the future.

Why Svivlo?

Svivlo might sound like a made up word but is in fact a old Norse for “spinning around” and also a dialect of “Svirvel” which was a fishing lure made out of tin.

What better reason than this to name our brand Svivlo.

Frequently Asked Questions

Do I still need the centrifugal brake?

No! The centrifugal brake drastically shortens cast distance as it brakes all the time and more the more distance you need

Do I still need the magnetic brake?

No! The magnetic brake drastically shortens cast distance as it brakes all the time and more the more distance you need

Do I need the spool tension brake?

No! The spool brake is normally not used but adds the ability to adjust the aggressiveness of the CastGuard under extreme conditions.

Do I need to use my thumb?

No, not to stop backlash! Under normal circumstances CastGuard will eliminate backlash. You only need to use your thumb to stop the lure at a specific spot.

How does CastGuard™ work?

The CastGuard™ technology is a 100% mechanical alpha brake system, activated by spool deceleration. Brake force is applied to pick up line slack. Initial brake force uses Euler force, and once the brake is activated it uses centrifugal force. When the line slack is picked up, CastGuard™ instantly deactivates and enables free spool. CastGuard™ is deactivated during acceleration and adjusts brake force automatically throughout the cast.

About Svivlo

Svivlo was founded by the watchmaker Sten-Thore Zander and his son Patrik Zander. As a watchmaker who has spent his whole life managing small complex objects in motion and as an angler getting backlash he decided to do something about the problem. After many years, thousands and thousands of hours engineering, building and testing he finally solved the baitcasters Gordian knot and invented the world´s only properly working cast brake.
