Matrix 3d feeder arm adjust

[Marker50]

hi.when i try to adust the arm using the large wheel it goes in big jumps ie rod under water to rod tip high..
I use the arm on my chair so it goes near top of leg as i would have to remove leg to fit lower everytime .
Is that the problem

I fit mine to the leg before fitting the leg ie under the seat - if that makes sense. I can then adjust the arm by sliding it up & down the chair leg. I use the same arm for float & feeder fishing so adjust it when I change method. Mines a Korum chair & a Preston arm.
