Magnetic brakes work by the attraction of magnets on the spool rotor, closer proximity of the magnets to the rotor greater magnetic attraction on the rotor = more braking ( dial up ).
Centrifugal brakes work in a different fashion, they work upon the distance of the wight in relation to the spool shaft, further away from the spool shaft more centrifugal force = more breaking ( pushing away the weight from the spool shaft ).
Hybrid systems incorporate both mechanisms, in theory you can make finer adjustments to the spool braking by fine tunning one or the other mechanism.
However there 's a catch, some systems do better on certain applications than others, and you also have certain braking systems in some reel models that you can 't find in others.
Daiwa has 3 magnetic systems: Magforce, Magforce V and Magforce Z, plus 3 types of rotors: ordinary, Type R and Type R+.
Shimano adresses the braking power of their reels in different fashion: by changing the weights for further fine tunning, all compatible with their centrifugal weight system. Upper end Shimano reels come with pre installed weights plus a bag with an extra set of weights ( identical in weight to the ones preinstalled ) and with an extra set of heavier weights for heavier baits.
How to set a centrifugal weight:
By pushing out the weights in a confuguration that maintains the spool balanced, so with six weights you have the following possible configurations:
o = all wights inactive
I = 2 weights activated
Y = 3 weights activated
X = 4 weights activated
O = 6 weights activated
That 's how they work, but that doesn 't mean that the system works the same way in all reels, one way is how it works and another thing is how that system works in a particular or reel model; regardless of the braking system, spool control is where it 's always been ---> in the thumb.
When you 've fished with a certain reel brand you get used that the reels will brake ( like you want ) with a particular brake setting; i can jump from my old Curados to my Metaniums of Chronarchs and I know how they brake, that doesn 't apply if I change to another system ( for ex if I jump from Shimano to Daiwa ) or to another brand ( Shimano or Daiwa to let 's say AbuGarcia ), if I change then I have to make some casts to adjust the braking system in such a fashion I can control the spool rotation without backlashing ( it 's all in the thumb ), I have to get the hang of it.
