Simple Tuning Guide for Murto wobblers

18.04.2009 Petri Rantanen

Ready for fishing when taken out of the box - but how efficiently?

All of the wobblers are tank tested at the workshop, but for gaining the optimum swimming action it
is often worth tuning the wobbler in the actual fishing conditions. Adjusting the wobbler is not hard,
when you remember to be careful and do the adjustment in small steps at a time.

Primary adjustment - Adjusting the front loop

The front line loop can be turned up or down to affect “kicking” intensity (1.2). When you turn the
front loop down, you will get a larger action. Turning the loop up tightens the swimming action. When
fishing in very fast flowing waters, the front loop can be turned up to gain a stable swimming action.
If the wobbler is swimming one flank upwards, or tilting to one side you can fix this by turning the
front loop sideways towards the tilting direction (1.1).

Secondary adjustment - Adjusting the swimming lip

All Murto wobblers can be adjusted carefully by bending the swimming lip (2). In case the adjustment
is done on a really cold day (for ex. during winter) the lip should not be bent without heating it up a
little bit (for example In a coffee cup).
Adjusting the lip follows the same principles as turning the front loop. When you turn the swimming
lip down, you will get a larger action. Turning the lip up tightens the swimming action.


Special adjustments - Seeking action and “wrist action”

Seeking means sort of a wild swimming, where the wobbler differs from its “swimming path”.
To adjust the wobbler to seek irregularly, you always need flowing water. Basic action can be adjusted
in a tank, but the wobbler will act differently in the real conditions. Most of the time it is most
reasonable to do the basic adjustments in still water and after that do the final adjustment in flowing

Seeking is most often achieved by turning the front line loop downwards so that most of the mass in
the wobbler’s body is above the point where the line is pulling the wobbler. If this doesn’t give you as
much seeking as you would wish, you can bend the horizontal part of the swimming lip upwards.
To affect the irregularity of the seeking action the basic principle is to make the wobbler unbalanced.
This can be done for example by turning the rear hook loop to the side (3). This will deviate the mass
centerpoint slightly and the swimming must now be corrected by turning the front loop sideways.
Some of the Murto wobbler models have their front lip glued a little bit tilted to achieve irregularity
to the swimming action.

The wrist action means that the wobbler is swinging sideways so that is is showing its flanks.
The wrist action can be affected by turning the belly hook loop sideways (4).
Turning both of the hook loops will often give delicious combinations.

Two wobblers with similar adjustments - why do they swim differently?

There are many factors that will affect the final lure. For example some of the models have a wooden
body that is formed or modified individually using hand tools. The weight of the wooden bodies might
differ and also the mass in the wooden body is often not evenly distributed. The position of the metal
wire inside the body used for making the loops might differ. The swimming lip position might also
differ. All handmade wobblers are individuals in some way - this means that each wobbler should be
adjusted individually.
