The EFF2S-100 Electronic Freefall is mechanical clutch free which increases the speed of the motor on the way down, comparably as fast as you can freely drop your anchor. By only increasing the drop speed you eliminate the risks compared to increasing the motors speed both up and down, which could lead to overloads, battery drainage, and winch failures. Compatiable with Savwinch Drum winches up to 2000 series.
