Multipliers-Mag brakes and centrifugal brakes.

Hi guys, I am getting a multiplier. Now what is the difference between Mag and Centrifugal brakes?
Which one is better?

Also which kind does the Daiwa 7HT(just the regular 7HT) have?

centrifugals are brakes that reduce or increase the amount of spool motion, making them faster or slower, they usually come in the form of end caps that can be tightened or loosed. the caps apply pressure to the central pin running between the spool itself and the bearings.
mags are magnets that also control the pace of the spool during a cast but by applying magnetic forces to the spools preventing it from running too fast should you not want it that way.
i prefare both, but centrifugals allow for more accuracy and precision.
the 7ht just has centrifugal brakes i think.

I think centrifugal breaks and end-cap pressure are two different things.

Centrifugal breaks are small weights on bars attached at right-angles to the spool spindle. As the spool rotates, the weights slide out and rub against a barrel creating friction and slowing the spool down.

Like "twirling" a weight on a piece of string, the faster you twirl the weight, the more outward force there is.

As far as I know, centrifugal breaks can only be "adjusted" by putting in larger or smaller weights or by removing one of the two weights.

Here's a pic of the centrifugal brakes in my SL20SH. (7HT wasn't to hand but it's a similar design.)

Teacher is correct in what he is saying, end tension is adjusted via the knobs on one or both end plates on a multiplier, in reality they should not be tightened as that will cause damage to the spool bearings or in extreme cases bend the spindle. There should always be a very slight amount of side to side movement on the spool.

Centrifugal brakes are either fibre or plastic blocks of varying sizes which are fitted onto small shafts which spin during the cast forcing them out against a friction ring.

Magnetic brakes come a variety of designs but the basic principle is the same, a magnetic field resists any conducting material that moves through it, in this case a spool. By varying the distance from the magnet to the spool you adjust the amount of braking.

Another form of braking used in conjunction with all the above methods is the oil in the bearings, a thicker oil will cause the spool to run with more braking, a thinner oil will allow it to run with less.

Hope this helps

i stand corrected :oops:

So are they ment to prevent birdsnests?

They will help reduce the chances of you getting a birds nest but a smooth casting style will be of more benefit. Someone with a poor technique will have to run a reel with so much braking that even medium distance fishing becomes a problem.
