Savage Gear Gravity Twitch SR has a magnetic long cast system with a sliding iron core. This system makes long and precise throws into a children's game and and the chamber sends out a very characteristic sound.

In the case of a regular inspiration, wobbles and kicks bait provocatively and is extremely stable even in strong flowing water.
The bait is suspending at long spin stops and it is often then that the fish fits.

A good bait for perch, trout, salmon and aspen.
