Ice Eater is shipped complete with suspension lines and shackles. Therefore, it can be taken out of the box, hung from a boat, dock, or pier and plugged in. Unlike other de-icing units, Ice Eater requires no additional hardware to obtain the desired de-icing pattern. Just move a shackle from one hole to another hole on the top rim, and you can quickly change the angle the Ice Eater is suspended at. The average operating depth of the Ice Eater is between two and three feet, but for best performance, ensure there is at least one foot between the Ice Eater and the seabed. .
