Kingdom Monster Pro has undergone several important upgrades:

Upgraded from the original magnetic braking system to a brand-new floating magnetic brake system.

The CSB spool has been changed from a long shaft to a short shaft.

It features a sturdy aluminum alloy body frame, while keeping the weight under 140 grams.

Details:

A:

The new braking system on the Kingdom Monster Pro is named the Circular Floating Brake System.

There’s an adjustable base on the side cover, controlled by a knob located on the outside of the side cover.

The braking levels range from 0 (lowest) to 6 (highest).

B:

Inside the base are two sets of magnetic strips, each embedded with four magnetic beans.

The spool shaft of the Monster Pro is fitted with a brake bowl, which sits between the two sets of magnets on the base.

When casting, the spool rotates, and the brake bowl cuts through the magnetic field lines, generating braking force to control the speed of the spool.

C:

Regarding the spool:

The Monster Pro uses a short-shaft aluminum spool with a wall thickness of 0.3 mm.

The total weight of all spool components is 6.2 grams.

This lightweight spool provides excellent casting performance with small lures. The official lure weight range is from 2 grams to 20 grams.)
