Kaster is low-profile model of the Colmic range, and it is a very simple reel in structure and mechanical concepts. The weight is very light, just 220 grams, and it features a very smooth retrieve ensured by 6 stainless steel ball bearings plus an extra one for the one-way clutch system. The body is made of ultra-light resin and it is painted with a special rubberised paint, that protects from scratches and seals the reel from water leakage. The spool is made of aluminium and lightened by holes. The clutch features Dartanium washers and allows to perform well during heavy and long lasting fights. The adjustment of the magnetic brake is easy and quick, by the sliding side plate that opens by just pressing the button.

The gear ratio is 6.2:1.
